what is diffetence between heat and temperature?
Answers
Heat is the total energy of the motion of the molecules of a substance whereas the temperature refers to the measure of the average energy of the motions of the molecules in the substance. The heat is dependent on factors like the speed of the particles, size of the particles and the number of particles etc.
The temperature, on the other hand, is independent of these factors. For example, let’s compare a tub of water with a cup of water. The water in the tub and the cup can be at the same temperature but by the virtue of the number of particles in the tub, the water in the tub has more thermal energy in it and thereby more heat even though they have the same temperature.
A temperature is a number that relates to the energy possessed by the molecules of a substance, which directly relates to the kinetic energy possessed by the particles of the substance. The SI Unit of temperature is degrees, Kelvin. As we said earlier, the temperature is directly related to the kinetic energy of the molecules, therefore if you double the temperature (in degrees Kelvin) of a substance, you double the average kinetic energy possessed by those molecules.
Answer:
heat is the internal amount of energy contained in a body due to the random molecular motion. it flows from a hot body to a cold body. SI unit of heat is joule. measured using a calorimeter.
Temperature is the measure of hotness or coldness (thermal state) of a body. it rises when the body is heated and falls when cooled. SI unit of temperature is Kelvin. measured using a thermometer.
