Question

Suppose a body of mass $m$ and specific heat capacity $s$ is at temperature $T_{2}$. Let $T_{1}$ be the temperature of the surroundings. If the temperature falls by a small amount $d T_{2}$ in time $d t$, then the amount of heat lost is

• A. $d Q=-4 \, m s \, d T_{2}$
• B. $d Q=2 m s \, d T_{2}$
• C. $d Q=m s \, d T_{2}$
• D. $d Q=-2 \, m s \, d T_{2}$

Answer 1

Answer: (C)

Correct answer is (c) $d Q=m s \, d T_{2}$
