a) A 3 litre vessel contains gas at a pressure of 200KPA. five litres of gas at the same pressure is forced into the vessel. calculate the new pressure of gas?
My answer was 75KPA which is incorrect
b) A vessel contains 2 litres of gas pressure of 300KPA and a temperature of 27oC. 3 litres of gas at the same temperature and pressure are forced into the vessel. the temperature is then raised to 127oC. Calculate the new pressure of gas?
