Question

A gas with a pressure of 6 atmospheres is cooled from 500 K to 250 K, what is its final pressure?

• A. 3 atmospheres
• B. 9 atmospheres
• C. 250 atmospheres
• D. 0.5 atmospheres
• E. 12 atmospheres

Answer 1

The correct option is A 3 atmospheres

$\frac{P_1}{P_2}=\frac{T_1}{T_2}$
$\frac{6}{V_2}=\frac{500}{250}$
$P_2=\frac{6\times 250}{500}=3$ Atmosphere.
