Heat Energy Measurement I

Performance Objectives

Students should be able to;

1. Explain the relationship between the heat supplied to a substance.

2. Explain the terms specific heat capacity and thermal capacity.

3. Explain why there is unequal rise in temperature for different substances of the same mass supplied with the same quantity of heat.

1. Calculate unknown quantity of heat using the relations Q = MCDT when no change of state is involved.

Specific Heat Capacity

Content

Specific heat capacity of a substance is the heat required to raise the temperature of a unit mass(1kg)  of the substance through a degree rise in temperature(1⁰C or…
