the colder the air the more dense it is and therefore the more oxygen it contains, but you will need to increase the amount of fuel otherwise the mixture will be lean and the engine will overheat.

I would recommend you just put a trickle charger on the battery, change all the fluids, put some stabilizer in the gas, and leave it stored until you need it, by what your doing, you are causing more harm then good, if the oil doesn't get up to temp, it slowly collects moisture (not good) and not only that, since the oil doesn't get up to temp, the engine gets more wear.

If there is combustion, there will be SO2.  The temperature will depend on the construction of the system, distance to chimney,etc.  The temperature of the flame will be constant depending on the type of oil.

A liquid is not frozen, it is liquid. Liquid nitrogen is liquid, you can pour it. Freezing Point @ 1 atm: -346.0°F (-210.0°C, 63oK) puts it in a solid state.

probably at around 200f.(i dont exactly know what temperature)  i have drove through areas, where the temperature is at 120f, and nothing happens to the roads.  besides the first thing that will happen is getting a flat tire, since tires are made of rubber.

When Scientists and Engineers complete the building of a particularly new engine, the initial running test of this engine is termed as a "cold start", or basically the test run of the new engine.  Another interpretation is the initial starting of any engine from its cold state.  Therefore, at anytime an engine is initialize to start, the period from when the engine is cold and running is referred to as a "COLD START".  Since all machines normally becomes hot as it gradually reach normal operating temperatures. Some engines are given a cold start to initialize it, as it gradually reach normal operating temperature, only then are they given a load, or engaged to do work. Cold starting prepares the engine and its parts to reach normal operating temperatures so that all of the function and processes can run smoothly within the normal conditions and parameters that it is expected to operate on and further monitored by sensors to maintain its safe operation.\n~meow

A typical liquid engine uses hydrogen as fuel and oxygen as oxidant; a typical solid propellant is nitroglycerine. In the liquid engine, the fuel and oxidant are stored separately at extremely low temperatures; in the solid engine, the fuel and oxidant are intimately mixed and loaded directly into the combustion chamber. A solid engine requires an ignition system, as does a liquid engine if the propellants do not ignite spontaneously on contact.

It's not quite so simple as that. Certain chemical makeups have different values, and viscosity won't necessarily dictate boiling point. \nExample, Antifreeze is pretty close to water, yet it's boiling temperature is much, much higher. It's freezing point is much lower as well, which makes it such a useful fluid in a car. \n\nOn the contrary, Gasoline is going to simply explode/ignite if you put a flame to it, as opposed to water just bubbling. \n\nBasically, it really goes both ways, and you really just have to know which fluids you're dealing with, and their values.

The Society of Automotive Engineers, usually abbreviated as SAE, has established a numerical code system for grading motor oils according to their kinematic viscosity. For single-grade oils, the kinematic viscosity is measured at a reference temperature of 100 °C (212 °F) in units of mm²/s or the equivalent older non-SI units, centistokes (abbreviated cSt). Based on the range of viscosity the oil falls in at that temperature, the oil is graded as an SAE number 0, 5, 10, 20, 30, 40, 50, or 60. The higher the viscosity, the higher the SAE grade number is. These numbers are often referred to as the weight of a motor oil.

The melting point of a crystalline solid is the temperature at which it changes state from solid to liquid. When considered as the temperature of the reverse change from liquid to solid, it is referred to as the freezing point.\n\nFor most substances, melting and freezing points are equal. For example, the melting point and freezing point of the element mercury is 234.32 kelvins (−38.83 °C or −37.89 °F). However, certain substances possess differing solid-liquid transition temperatures. For example, agar melts at 85 °C (185 °F) and solidifies from 32 °C to 40 °C (89.6 °F to 104 °F); this process is known as hysteresis. Certain materials, such as glass, may harden without crystallizing; these are called amorphous solids.\n\nThe melting point of water at 1 atmosphere of pressure is 0 °C (32 °F, 273.15 K), this is also known as the ice point. In the presence of nucleating substances the freezing point of water is the same as the melting point, but in the absence of nucleators water can supercool to −42 °C (−43.6 °F, 231 K) before freezing.\n\nUnlike the boiling point, the melting point is relatively insensitive to pressure. Melting points are often used to characterise organic compounds and to ascertain the purity. The melting point of a pure substance is always higher than the melting point of that substance when a small amount of an impurity is present. The more impurity is present, the lower the melting point. Eventually, a minimum melting point will be reached. The mixing ratio that results in the lowest possible melting point is known as the eutectic point.\n\nThe chemical element with the highest melting point is tungsten, at 3695 K (3422 °C, 6192 °F). The often-cited carbon does not melt at ambient pressure but sublimates at about 4000 K; a liquid phase only exists above pressures of 10 MPa and estimated 4300–4700 K. Tantalum hafnium carbide (Ta4HfC5) is a refractory compound with a very high melting point of 4488 K (4215 °C, 7619 °F).[1] At the other end of the scale, helium does not freeze at all at normal pressure, even at temperatures infinitesimally close to absolute zero; pressures over 20 times normal atmospheric pressure are necessary.\n\n\n--------\n\n\nThe boiling point of a substance is the temperature at which it can change its state from a liquid to a gas throughout the bulk of the liquid at a given pressure. A liquid may change to a gas at temperatures below the boiling point through the process of evaporation. Any change of state from a liquid to a gas at boiling point is considered vaporization. However, evaporation is a surface phenomenon, in which only molecules located near the gas/liquid surface could evaporate. Boiling on the other hand is a bulk process, so at the boiling point molecules anywhere in the liquid may be vaporized, resulting in the formation of vapor bubbles.\n\nA somewhat clearer (and perhaps more useful) definition of boiling point is "the temperature at which the vapor pressure of the liquid equals the pressure of the surroundings."\n\nThe reaction\n\nSomething that should not emembered is that boiling is evidenced by the appearance of bubbles containing vapor from the liquid. [Note: The bubbles that precede real boiling in the pot on the stove are either (formerly) dissolved gas or water vapor forming on the very hot bottom of the pot that will be condensed before it can get to the top of the liquid.] Production of vapor requires energy and thus does not occur without some source of energy. This source can be a hot surface or even the liquid itself. Hot liquid will boil as it rises through the bulk liquid if the pressure of the environment drops to the vapor pressure of the liquid at its temperature. This production of vapor will not quickly stop because the temperature of the liquid will not be reduced by the vaporization thus reducing the vapor pressure.\n\nSaturation temperature and pressure\n\nA saturated liquid or saturated vapor contains as mu

It depends on the temperatures of the clouds.\n\nClouds that are below freezing: you would want ONE of these ice-forming agents:\n    1) silver iodide (most common)\n    2) dry ice\n    3) compressed liquid propane\n    4) carbon dioxide\n\nClouds that are warm: you would want ONE  of these droplet-forming agents:\n    1) salt (most common)\n    2) urea\n    3) ammonium nitrate

When a solid is heated, the molecules become active and the bonds between them come looser, this is how a solid becomes a liquid.\nThe warmer the liquid becomes, the molecular bonds become even less connected and the liquid becomes a gas. (evaporation)\n\nWhen a gas is cooled, the molecular bonds change and they become tighter. or closer together causing the gas to turn back into a liquid (condensation).  And as the molecules become tighter still, then the liquid turns back into a solid.\n\nFreezing and melting points change per molecule.

I believe it's cooled to prevent pre-detonation of the fuel/air charge in the cylinder. So, if you send the hot gasses back into the manifold without cooling, you'll get knocking in the engine.
