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.

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 ...

The use of nanocomposites, which use small-scale particle fillers to enhance the characteristics of thermoplastics and thermosets, has attracted a lot of attention in recent years. For instance, ...
