Any help on this question please??
At 25.00 degrees C and 100.0kPa, a gas occupies a volume of 20.00dm^3.
Calculate the new temperature of the gas if:
a) The volume is decreased to 10.00dm^3 at constant pressure. (we are told to use the data from the question to calculate moles as that won't change at different temperatures)
b) The pressure is decreased to 50.00kPa at constant volume.
Is it a case of just alter the volume and pressure and keep the remaining ones the same??
