176 grams of \(\mathrm{CO}_2\) can change its temperature from \(0^{\circ} \mathrm{C}\) to \(30^{\circ} \mathrm{C}\) by absorbing 3600 joules of thermal energy. Molar specific heat of \(\mathrm{CO}_2\) in \(\mathrm{J} \mathrm{mol}^{-1} \mathrm{~K}^{-1}\) is
- A 30
- B 40
- C 50
- D 60
Answer & Solution
Correct Answer
(A) 30
Step-by-step Solution
Detailed explanation
\(\begin{array}{ll}& \Delta \mathrm{Q}=\mathrm{nC} \Delta \mathrm{T} \\ \Rightarrow & 3600=\left(\frac{176}{44}\right) \mathrm{C} \times 30 \\ \Rightarrow & 3600=120 \mathrm{C} \\ \Rightarrow & \mathrm{C}=30 \mathrm{~J} / \mathrm{mol} \mathrm{K}\end{array}\)
