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.

CBSE Class 11 Physics Thermal Properties of Matter Formulas: Find here a list of important formulas, definitions, graphs, and diagrams for CBSE Class 11 Physics Chapter 10, Thermal Properties of ...

DSC is a measurement technique commonly used for the determination of specific heat capacity because of its ease of use, short measurement times and because it provides adequate accuracy. The specific ...

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 ...

In DSC, the heat flow determined is directly proportional to the specific heat capacity. Hence C p is calculated directly from the DSC signal (Φ meas). In order to do this, the DSC curve is corrected ...
