The four plastic-foam soup bowls contain the same amount of water at
Rank the bowls according to the maximum temperature of the water after the cylinders are added.
To Rank: The bowls as per maximum temperature of water after the cylinders added.
Explanation of Solution
Introduction:
Thermal equilibrium refers to the attainment of same temperature by the two bodies when the thermal energy transfers from one body to another when placed in contact with each other.
The equilibrium temperature depends on the amount of thermal energy transferred which depends on the mass
Specific heat of plastic foam is
Specific heat of water is
The temperature is high for case B and C but the mass of cylinders in case C is greatest. Thus, the maximum temperature of water would be in case C, then B followed by A and least in case D.
Conclusion:
The rank would be:
