Question

A bubble of $n$ mole of helium is submerged at a certain depth in water. The temperature of water increases by $\Delta t^{\circ }C$. How much heat is added approximately to helium during expansion?

• A. $n{c}_v\Delta t$
• B. $\frac{n{c}_p}{\Delta t}$
• C. $\frac{n^2{c}_v}{\Delta t}$
• D. $n{c}_p\Delta t$

Answer 1

Answer: (D)

$H=n{c}_p\Delta t$
