At 0°C, the volume of a gas is 22 liters. For each degree the temperature T (in degrees Celsius) increases, the volume V (in liters) of the gas increases by 225 . Write an equation that represents the volume of the gas in terms of the temperature.
I believe there is a typo here. Using ideal gas equation, the increases for every degree would be 22L/273= 0.08L= 2/25 liter. So, it seems the number 225 means 2/25.
Since every degree(T) means an increase of 2/25L in volume, the equation would be V(in liters)= 22 + 2/25 T
