i have this tinsy question about physics. temperature and heat are two diffrent things, right?

Answer 1

Another way to look at the difference is this:

Temperature is an intensive quantity
Heat is an extensive quantity

Intensive means that the quantity doesn't depend on how much of a substance you have. For example, if a block of material is in thermal equilibrium, no matter where you measure it the temperature will be the same.

Extensive means that the quantity DOES depend on how much. Thermal energy (or heat) is extensive, meaning that if you have twice the mass of a substance at temperature T, then you have twice the thermal energy.

Temperature, by itself, is not a measurement of thermal energy. But it is necessary to know temperature to calculate thermal energy.The other two quantities you need to know is the mass and the heat capacity of the material.

Answer 2

Heat is thermal energy, a global property. It's the amount of total energy an object would lose if all molecular motion was brought to a stop. Temperature is a thermodynamic local property of of any object which contains heat. Its formal definition is rather abstract, but it has the property of being uniform in thermodynamic equilibrium, and it generally increases as the heat content of an object increases. The ratio of how much the heat changes for a given change in temperature is call the object's "heat capacity"

Answer 3

Heat is a kind of energy. The larger an object is, and the greater its specific heat, the more heat energy is needed to raise it to a specific temperature. A match, for instance, has a very high temperature, but because it's small, it doesn't contain much heat. An iceberg has a very low temperature, but it's huge, and ice has a VERY high specific heat, so the iceberg actually contains way more heat energy than the match.

Answer 4

Yes, the TEMPERATURE is the AVERAGE kinetic energy of the particles of an object ;where as the HEAT is the TOTAL kinetic energy of the particles of an object.
Also, the temperature does not depend upon the mass (amount of matter) of the object, where as the heat does depend upon the mass of the object.

Answer 5

Temperature is a number that is related to the average kinetic energy of the molecules of a substance. If temperature is measured in Kelvin degrees, then this number is directly proportional to the average kinetic energy of the molecules.

Heat is a measurement of the total energy in a substance. That total energy is made up of not only of the kinetic energies of the molecules of the substance, but total energy is also made up of the potential energies of the molecules.

More About Temperature

So, temperature is not energy. It is, though, a number that relates to one type of energy possessed by the molecules of a substance. Temperature directly relates to the kinetic energy of the molecules. The molecules have another type of energy besides kinetic, however; they have potential energy, also. Temperature readings do not tell you anything directly about this potential energy.

Temperature can be measured in a variety of units. If you measure it in degrees Kelvin, then the temperature value is directly proportional to the average kinetic energy of the molecules in the substance. Notice we did not say that temperature is the kinetic energy. We said it is a number, if in degrees Kelvin, is proportional to the average kinetic energies of the molecules; that is, if you double the Kelvin temperature of a substance, you double the average kinetic energy of its molecules.

More About Heat

Heat is energy.

Heat is the total amount of energy possessed by the molecules in a piece of matter. This energy is both kinetic energy and potential energy.

When heat, (i. e., energy), goes into a substance one of two things can happen:

1. The substance can experience a raise in temperature. That is, the heat can be used to speed up the molecules of the substance. Since Kelvin temperature is directly proportional to the average kinetic energy of molecules in a substance, an factor increase in temperature causes an equal factor increase in the average kinetic energy of the molecules. And if the kinetic energy of the molecules increase, the speed of the molecules will increase, although these increases are not directly proportional. The kinetic energy of a body is proportional to the square of the speed of the body.

2. The substance can change state. For example, if the substance is ice, it can melt into water. Perhaps surprisingly, this change does not cause a raise in temperature. The moment before melting the average kinetic energy of the ice molecules is the same as the average kinetic energy of the water molecules a moment after melting. Although heat is absorbed by this change of state, the absorbed energy is not used to speed up the molecules. The energy is used to change the bonding between the molecules. Changing the manner in which the molecules bond to one another constitutes a change in potential energy. Heat comes in and there is an increase in the potential energy of the molecules. Their kinetic energy remains unchanged.

So, when heat comes into a substance, energy comes into a substance. That energy can be used to increase the kinetic energy of the molecules, which would cause an increase in temperature. Or that heat could be used to increase the potential energy of the molecules causing a change in state that is not accompanied by an increase in temperature.

Answer 6

Yes temperature can be very high like in fully burned coals, but they have very little heat (temp * mass) so you can walk on fire without getting burned.
Heat takes into account the mass of the object (and therefore the energy)
Temperature does not

Answer 7

heat is the total energy inside body due to molecular motion. that is why it has same unit as that if energy.
teprature is what determines the flow of heat between two bodies in contact.
let a very big rooh has 20(heat) kids & a very small room has 16 kids(heat) if there common door is opened kids will go from smaller room to bigger. thus total no. of kids in a room is like total energy i.e.
heat but flow of kids is controlled by something else that depends on total kids & size of room that is what is equivalent to temperature

Answer 8

Heat is the amount of thermal energy transfered from one system to another. Temperature is a measure of the tendency of one system to transfer thermal energy to another system.

Answer 9

yes! temperature is denoted by T and heat usually q though there are different kinds of heat.

Answer 10

degree of hotness or coldness measured on a definite scale =temperature
to become warm or hot=heat
