What happens if: (fill in the blanks) The number of moles is halved, the pressure ___ The temperature is tripled, the volume ___ The temperature is quadrupled, the pressure ___ The pressure is doubled, the volume ___ The pressure is cut by 1/3, the volume ____ Solution According to the ideal gas law , pV = nRT , pressure , volume and temperature are related to each other. So here : The number of moles is halved , the pressure halves. The temperature is tripled , the volume triples. The temperature is quadrupled , the pressure quadruples. The pressure is doubled , the volume halves. The pressure is cut by 1/3 , the volume triples. .
