Question

Which of the following statements is true for the specific heat of solids at constant volume $(C_v)$ ?

• A. It is independent of temperature
• B. It increases with rise in temperature and its value is different for different solids at high temperatures
• C. It increases with rise in temperature and its value become $3R$ for different solids at large temperatures
• D. Its value becomes zero for different solids at large temperatures

Answer 1

Answer: (C)

Specific heat of solids at constant volume increases with rise in temperature and its value becomes $3R$ for different solids at larger temperature
