Physics Question on thermal properties of matter
Calorimeters are made of which of the following?
A
wood
B
glass
C
metal
D
either (a) or (b).
Answer
metal
Explanation
Solution
From the principle of calorimetry, the heat lost by a hot body is equal to heat gained by the cold body. Therefore during this process, heat exchange must be quick, otherwise some heat is lost due to radiations. As the metals are good conductors, therefore heat exchange will be quicker.
