15 L of gas at STP is subjected to four different conditions of temperature and pressure as shown below. In which case the volume will remain unaffected?

A

`273 K,` 2 bar pressure

B

`273^(@)C`, 0.5 atm pressure

C

`546^(@)C`, 1.5 atm pressure

D

`273^(@)C`, 2 atm pressure

Text Solution

Verified by Experts

The correct Answer is:
D
`V_(1)= 15L, P_(1)= 1 atm, T_(1)= 0^(@)C" or "273.15K, P_(2)= 2 atm, T_(2)= 273^(@)C" or "546.15K, V_(2)= ?`
`therefore V_(2)= (P_(1)V_(1))/(T_1)xx (T_2)/(P_2)= (1xx 15)/(273.15)xx(546.15)/(2)= 15L`.
