why heat is measured in degree celcius? does it have angular measurement (degree)?

No it doesn't have angular measurement, it's another meaning of the word "degree"--there are several, all indicating discrete measurements of something. (Bachelor's degree--a certain amount of learning; I agree, to a degree--a certain amount of agreement)

None.\n\nCalories are a measure of the heat content of objects.  If you are referring to the amount of heat radiated by the earth, it would be stated in some unit appropriate to the measure of radiant energy, such as watts or newtons per second.\n\nYou may be able to find an answer by visiting the library or using the internet.

im not sure if that first answer was clear so...........\nAnything in the emperiment that you have control for.  for example say you are testing how fast water boils at a certain temperature.  the temperature is the controlled variable because you can change the temperature yourself by increasing or decreasing the heat... the controlled variable is independent.  If you had to make a chart or graph, it would be on the x axis...  im not sure if thats any clearer

Heat is a form of energy. \nTemperature is a measurement of the state of heat-energy in a certain body.

Degrees \nor Radians (used in higher classes mostly; pi rad = 180 deg)\nor steradians (used to measure solid angle)

Thermometer Measures the Actual temperature, by the implementation of a device or mercury's reaction to the degrees.\n\nWind chill is a FACTOR- as it blows across our skin, the temperature is PERCIEVED to be colder, as our skin is being Cooled faster- the wind blows our body warmth away.\n\nWind chill factor is Calculated, Not Measured.

Amount of heat generated by a given mass of fuel when it is completely burned. It is measured in joules per kilogram. Calorific values are measured experimentally with a bomb calorimeter

Now, this answer depends on what you mean by Heat.  Strictly speaking Heat (symbol 'Q')is the energy transferred from one part of a substance to another, or from one object to another due to a change in temperature.  To give you an example, if you heat a spoon on a flame and then insert it in a glass of water, the latter will warm up since Heat moves from the hot spoon to the cooler water.  Heat is a measure of energy and so its units are Joules (J).  The amount of Heat energy transferred is calculated by the formula Q=mcdT (mass x specific heat capacity x change in temperature)\n\nNow, if you are still studying basic Physics, you might come across definitions of Heat which state that it is the Energy driving the vibrations and movement of molecules.  In further Physics this will be called "Internal Energy", symbol 'U'.  In fact, the internal energy of a body can either be changed by giving or taking Heat (with a temperature difference) and/or by doing Work (that is why if you rub your hands together they warm up, despite being at the same temperature).\n\nTemperature is a measure of the degree of hotness of an object (not a measure of the amount of Heat in it!).  So, if an object has a temperature of 0 degree Celsius, this means that this object is as "hot" as pure melting ice.  In the same manner, a stone at a temperature of 100*C is as "hot" as steam above boiling water, and so on.  So, temperature is really a comparison.  There is an Absolute Temperature Scale devised by Kelvin in 1848, who found out that the lowest possible temperature is -273*C.  At this temperature all molecular movement is thought to stop and therefore there cannot exist a place colder than a place where there is no Internal Energy, and hence no heat!  Therefore this temperature is called Absolute Zero, and a temperature scale starting from this point, 0 K(elvin) (=-273*C), was set up. (e.g. 10*C = 10 + 273 = 283K).

Heat is just a form of energy.\n\nTemperature is the measure of the Average Kinetic energy of a substance.\n\nWhen you add heat energy to something, its moleculues gain kinetic energy is move around faster, thus increasing its temperature.\nWhen a substance changes phases (going from Solid to liquid for example), intermolecular forces must be over come, this requires energy...all the while, the temperature remains constant.

I will take a stab at it.  I am guessing it is because water has more degrees of freedom.  In the liquid there is also rotational degrees of freedom to absorb energy that the solid ice does not have.\n\nTo Neil, the formulas are for heat capacity and have nothing to do with the way something is heated, only the amount of energy that it takes.\n\nNor does it have anything to do with Newton's law of cooling.

The sources of error will always depend on the way you carry out the experiment. To measure the heat directly wouldn't work well. So you need to monitor the temperature at both ends. Monitoring the temperature at both ends, the errors will be the scale error of your measuring device, the quality of the thermal contact between the sensor and the fluid as well as the effect that the sensor has on the flow of the fluid (I'd use fibre optic sensors as they are non-invasive and don't have the problems asociated with using electrical test equipment in water).

There is a formula...but this is much easier\n\nhttp://www.onlineconversion.com/temperature.htm

Celsius. In my country, Celsius is used. I once learned how to convert Celsius into Fahrenheit but it still confuses me. Yesterday I looked up the weather forecast in Yahoo! Weather and I thought: How could it get so hot tomorrow? It´s winter! Then I realized that the temperature was given in Fahrenheit.

1/2*k*T gives the temp of a gas with temp T in kevins.k gives the nos of terms we can write while writing the expression for the energy of a molecule(we can have linear,rotational,vibrational motion depending upon the shape and size of molecules).this is the law of equipartition of energy which relates the temp. and internal energy.so temp indeed tells us of the amount of energy carried by a body

well it depends on the angle between quantities. \nat 0 degree, simply add the given magnitude\nat 90 degree, use the pythagorean theorem\nat 180 degree, simply subtract the magnitude\nat any angle, other than 0, 90 and 180, use the laws of sine and cosine

well u need it in mensuration when u need 2 find the area of a circle and stuff. it's a very imp constant whose value i 22/7 or 3.14\nalso, 180 degrees = pi radian which u need in physics and calculas

In weight, it's the same. No mass has been added or taken away by heating it or cooling it down, weight doesn't care about tempurature except possibly at phase changes.\n\nIt does however become more dense until about 4 degrees centigrade, so water of a certain volume at 4 degrees centigrade ways more then water of the same volume at 10 degrees centrigrade. This is because the 4 degree centigrade water is more dense so to get the same volume you need to add more mass.
