Question

The volume of 350. mL of gas at 25°C is decreased to 250. mL at

constant pressure. What is the final temperature of the gas?

Answer 1

V1/T1 = V2/T2

V1 = 350. mL

T1 = 25 + 273 = 298 K

V2 = 250. mL

T2 = ?

Solve the equation for T2: T2 = V2T1/V1 = (250. mL)(298 K)/(350. mL) = 213 K = -60°C
