(a) An ideal gas in a 1.5L flask is initally at a pressure of 1000kPa and a temperature of 20oC. What would be the new pressure in the flask if the temperature was increased to 50oC?
(b) How many moles of gas are in the flask?
(c) What temperature would be required to increase the pressure in the flask to 200kPa?
