List of top Physics Questions on thermal properties of matter asked in WBJEE

Temperature of a body \( \theta \) is slightly more than the temperature of the surroundings \( \theta_0 \). Its rate of cooling \( R \) versus temperature \( \theta \) graph should be 

The apparent coefficient of expansion of a liquid when heated in a copper vessel is \( C \) and in a silver vessel is \( S \). If \( A \) is the linear coefficient of expansion of copper, then the linear coefficient of expansion of silver is
The elastic potential energy of a strained body is:

A metal plate of area 10-2m2 rests on a layer of castor oil, 2 × 10-3m thick, whose viscosity coefficient is 1.55 Ns/m2. The approximate horizontal force required to move the plate with a uniform speed of 3 × 10-2ms-1 is:
