Gas Laws question
I keep getting too many unknowns in this question and can't solve it. can someone help?
the pressure in the tube of a bicycle tyre is 500 kPa above atmospheric pressure of 100 kPa. the initial volume of air at atmospheric pressure trapped in the barrel of the pump by the piston is 2.00x10^-4 m^3. the temperature of the air is 17 degrees celsius. when the piston compresses the air the volume is reduced to 4.00x10^-5 m^3 and at that instant the one-way valve connecting the pump to the tube opens, allowing air to enter the tube. calculate the temperature of the air in the pump at this instant in degrees celsius.
