Question

# At what temperature would the volume of a given mass of a gas at constant pressure be twice its volume at $$0^oC$$?

A
546oC
B
100oC
C
273oC
D
373oC

Solution

## The correct option is D $$546^oC$$Given:- P= constant$$T_{1}= 0^{\circ}C$$ (273 K)$$T_{2}=?$$Let $$V_{1}=V$$$$V_{2}=2V$$$$\cfrac{V_{1}}{T_{1}}=\cfrac{V_{2}}{T_{2}}$$$$\cfrac{V}{273K}=\cfrac{2V}{T_{2}}$$$$T_{2}= 546K= 273\ ^0C$$ Hence, the correct option is $$\text{A}$$Chemistry
