Question:

If 50 cal of heat is supplied to the system containing 2 mole of an ideal monoatomic gas, the rise in temperature is :

(R = 2 cal/mol-K)

Options:

50 K

5 K

10 K

20 K

Correct Answer:

5 K

Explanation:

\(\frac{C_v}{C_P}*Q = n C_v dT\)

\(dT = \frac{Q}{n C_P} = \frac{50}{2*\frac{5}{2}*R}\)

\(dT = 5\) K
