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.

Physicists in the UK and Russia have revived concepts first put forth in the 1940s to develop a new theory of the heat capacity of liquids. Created by Dima Bolmatov and Kostya Trachenko of Queen Mary, ...

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 ...

Because the technique provides such significant benefits, and because the transitions (phase changes, chemical reactions, etc.) observed in a sample as it is heated are often very complex, the ...
