I've got the answer but I'm not sure about the method?
A gas cylinder has a volume of 0.024m3 and is fitted with a valve designed to release the gas if the pressure of the gas reaches 115kPa.
Calculate the pressure on the cylinder of this amount of gas at 8oC.
The molar gas constant has a value of 8.31 J mol-1 K-1. At Standard Temperature and Pressure (STP) 1 mole of any gas has a volume of 0.024m^3
At the start of a journey the pressure of the air in a car tyre is 180 kPa and the temperature is 18oC. After being driven the pressure is 303 kPa. Assuming that the volume of the air remains constant what is its temperature now?
The volume of a fixed mass of gas at 15oC was 0.078 m^3. The gas was then heated to 45oC without change of pressure.
Calculate the new volume of this gas.
i) A mass of gas occupies a volume of 200 cm^3 at a temperature of
27oC and a pressure of 1 atmosphere. Calculate the volume when:
a) The pressure is doubled at constant temperature
b) The absolute temperature is doubled at constant pressure
c) The pressure is 1.5 atmospheres and the Celsius temperature is 127oC
Can someone help and give me steps to these gas law equations?
