The new temperature of the gas is 669 °C.
Explanation:
Given
The volume
A second volume
Find
The second temperature
Strategy
A problem involving two gas volumes and two temperatures must be a Charles' Law problem.
The formula for Charles' Law is
#color(blue)(bar(ul(|color(white)(a/a)V_1/T_1 = V_2/T_2color(white)(a/a)|)))" "#
Rearrange Charles' Law to get
#T_2 = T_1 × V_2/V_1#
Solution
∴
The new temperature is 669 °C.
