This is Charles's Law which states that volume at condition one divided by the temperature at condition one is equal to the volume at condition two divided by the temperature at condition two.

The formula is:  V1/T1=V2/T2

This is Charles's Law which states that volume at condition one divided by the temperature at condition one is equal to the volume at condition two divided by the temperature at condition two.

The formula is:  V1/T1=V2/T2

Usually your problems are stated in degrees celsius (C) so you have to convert to Kelvin. The reason for this is so you never have to try dividing by zero which could happen if using the celsius scale.

To convert from celsius to Kelvin, you add 273.16 to the given celsius temperature.
