What is the temperature in kelvin of a gas if it is allowed to expand from 1.50 L to 4.50 L? The initial temperature is 10.0°C and pressure is constant throughout the change.
Which equation should you use?

StartFraction V subscript 1 over T subscript 1 EndFraction equals StartFraction V subscript 2 over T subscript 2 EndFraction.

T subscript 2 equals StartFraction V subscript 1 over V subscript 2 EndFraction T subscript 1.

T subscript 2 equals StartFraction V subscript 2 over V subscript 1 EndFraction T subscript 1.
