Whay the temperature increases when the pressure is increased?

PV=nRT is the formula you want to use to explain this. P is Pressure, V = Volume, n= Moles of molecule, R is a constant, T = Temerature. Now the reasoning behind this is because molecules that in the in gas phase want to be far apart from each other as possible. If you try to increase the pressure, you are forcing the molecules to come closer together. These molecules then rub up against each other more, creating heat.

When gas is compressed in a thermally insulated vessel the gas is heated.\n\nWhen pressure increases temperature increases.\n\nSimilarly if the gas is expanded in a thermally insulated vessel the gas is cooled.\n\nWhen the pressure decreases the temperature decreases. \n\nNear earth’s surface, the atmospheric pressure is very high.\n\nAt a height of 30km from the surface, the pressure of air is almost zero.\n\nThough the hot air goes up; as it goes up the pressure decreases and volume increases (density decreases) and as per the  gas equation the temperature decreases.

Mass is not affected by temperature, but volume can be slightly changed because if an object heats up, the particles begin to move faster and so it expands, or vice versa if the object gets cooler.

Temperature, property of systems that determines whether they are in thermal equilibrium (see Thermodynamics). The concept of temperature stems from the idea of measuring relative hotness and coldness and from the observation that the addition of heat to a body leads to an increase in temperature as long as no melting or boiling occurs. In the case of two bodies at different temperatures, heat will flow from the hotter to the colder until their temperatures are identical and thermal equilibrium is reached (see Heat Transfer). Thus, the terms temperature and heat, although interrelated, refer to different concepts, temperature being a property of a body and heat being an energy flow to or from a body by virtue of a temperature difference.\n\nTemperature changes have to be measured in terms of other property changes of a substance. Thus, the conventional mercury thermometer measures the expansion of a mercury column in a glass capillary, the change in length of the column being related to the temperature change. If heat is added to an ideal gas contained in a constant-volume vessel, the pressure increases, and the temperature change can be determined from the pressure change by Gay-Lussac's law, provided the temperature is expressed on the absolute scale\n\nHeat, in physics, energy transferred from one part of a substance to another, or from one body to another, by virtue of a difference in temperature. Heat is energy in transit; it flows from a substance at a higher temperature that is placed in contact with a substance at a lower temperature, raising the temperature of the latter and lowering that of the former, provided the volume of the bodies remains constant. Heat does not flow from a lower to a higher temperature unless work is done.

actually you should phrase it "why does pressure decrease when temperature is reduced?" because a rise or fall in temperature affects air pressure (not the other way around).  the higher temperature is, the faster molecules in the air are moving and therefore they increase the space they take up.  if temperature is lower, molecules move around less and require less space.

Tempreture effects the volume and pressure of the gas inside the balloon.\nAccording the this formula (Pressure . Volume)=(nR)(Temp)\nby increaseing temp you are gonna have smaller pressure and volume(thus smaller balloon) and by increasing temp, you are gonna have higher pressure and volume(thus bigger/stiffer) balloon.  \nKeep in mind the effect of temp on the volume and the pressure of the gas or liquid inside the balloon depends on many factors such as the type of gas or liquid, what the balloon is made of and...

Charles' law states that, under constant pressure, the ratio between a gas' volume and absolute temperature remains constant.  So if it heats up it expands and if it cools it contracts.  For example, you fill a balloon with helium at room temperature, and then put it in a refrigerator.  The helium will contract, and the balloon will shrink.

Not 100% sure. But I think its because the air inside isn't moving. The air inside is stationary, while it is continuously circulating outside, which causes changes in the temperature. IMHO

Direct sunlight or elevated temperatures will increase the temperature of the gas inside the container and thereby increase the pressure.  Very high temperatures can increase the pressure until the container bursts.

It mainly depends on the pressure (if we are talking about pure water). The higher the pressure, the higher the boiling point - it can be much lower (ex. high in the mountains) or much higher than 100 degrees C (the boiling point under normal atmospheric pressure). If we don't talk about pure water, then adding other chemicals (for example, table salt - sodium chloride) can raise the boiling point as well.

There are two conditions at which pressure in an air tank increase. If pressure in the tank is increased by adding more gas or liquid into the tank, it will definitely increase. However, if the pressure is increased by merely increasing temperature, it will not increase the weight of the tank.

its a high pressure heat with constant movement that create volume, density conductors

b\nThe concentration of the gas in the liquid is at equilibrium when the vapor pressure of the gas above the liquid equals the vapor pressure of the gas in the liquid.  Increasing the pressure above the liquid changes the equilibrium and  more gas is absorbed by the liquid.

yeaaaaah\n\nit's "expand and rise"\nthe energy (heat) supplied to it causes the individual molecules to have more energy and because of it, they expand further, and rise since density is lowered and volume is increased

Good question.\n\nPressure of the trapped gas is supposed to decrease with lowering the temperature.\n\nBut, water increases in volume as its temperature is increased below 4 degree C. In other words, water has the maximum density at 4 degree C. Increasing or decreasing its temperature from that point will make it expand.

Temperature increases as pressure increases due to increased molecular collisions.  The Earth generates an incredible amount of gravity, meaning that everything is pulled towards the center of the Earth.  So at the center of the Earth is an incredible amount of pressure due to the incredibly high density of molecules moving around there, and thus the temperature is incredibly high!
