- At a constant pressure, 3.00 L of a gas is heated from 300
K to 382 K. The final volume of the gas is
A) 1.00 L
B) 3.82 L
C) 7.64 L
D) 9.00 L

The correct answer is B) 3.82 L

Explanation:

We apply Charles's Law, where for a constant pressure, the temperature and volume vary directly proportionally (at higher temperature, higher volume and vice versa):

V1/T1= V2/T2

3,00L /300K= V2/382K

V2= (3,00L x 382K) / 300K = 3, 82 L
