The thermal capacity of 40g of aluminium (specefic heat=20cal/g/°C)is_
Correct answer: D. 8 cal°C^-1
- A. 40cal/°C
- B. 160 cal/°C
- C. 200 cal/°C
- D. 8 cal°C^-1
Explanation
Option D is correct.We know thatThermal Capacity= mcThermal capacity = 40 g x 0.2cal/g/°C = 8 cal/°C

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
