Water has a high specific heat capacity which we’ll refer to as simply “heat capacity”, meaning it takes more energy to increase the temperature of water compared to other substances.

Energy is the ability of a system to do work and the change of energy, while heat is the energy being transferred.

Friction Produces Heat But do you know why? Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer. Heat from friction can be useful.

In general, the specific heat also depends on the temperature. (Figure) lists representative values of specific heat for various substances. Except for gases, the temperature and volume dependence of the specific heat of most substances is weak.

1 Answer. The heat capacity is the slope of the plot of internal energy U with temperature T. Then as temperature increases more of the energy levels become excited & the internal energy rises rapidly and so does the slope of U vs T and so heat capacity increases.

Formula of Thermal Energy ΔT = temperature difference.

Some similarities are: 1) The more heat there is, the higher the temperature. 2) The less heat there is, the lower the temperature. 3) Mathematically the heat and the temperature difference between two points are proportional.

The heat is very important in our daily life in warming the house, cooking, heating the water and drying the washed clothes. The heat has many usages in the industry as making and processing the food and manufacture of the glass, the paper, the textile, ………etc.

The Earth’s internal heat source provides the energy for our dynamic planet, supplying it with the driving force for plate-tectonic motion, and for on-going catastrophic events such as earthquakes and volcanic eruptions.
