Question

A sample of argon gas occupies 50 liters at standard temperature & pressure. Find out the volume occupy by the gas if the temperature is doubled?

• A. 25 liters
• B. 50 liters
• C. 100 liters
• D. 200 liters
• E. 2,500 liters

Answer 1

Answer: (C)

100 liters

STP conditions : $T_i=273K$ $P_i=1$ atm

Given : $V_i=50$ liters

Thus final temperature of the gas $T_f=2T_i=546$ $K$

Using $\frac{V_f}{T_f}=\frac{V_i}{T_i}$ $(\because P=constant)$

$\therefore$ $\frac{V_f}{546}=\frac{50}{273}$ $⟹V_f=100$ liters
