When substances are heated, they gain heat energy. The atoms and molecules of substances gain kinetic energy and their speed increases. The average kinetic energy of these particles is proportional to ...
Heat is a one form of energy that runs from substance having high temperature to a substance with low temperature with respect to a specific matter. Heat is a one form of energy that runs from ...
An electric heater supplies 13500 joules of heat energy to a metal block of mass \(0.5kg\). The temperature of the block rises from \(20^{\circ}C\) to \(80^{\circ}C\) during the heating process.
