2.A fixed quantity of gas at 24 degrees Celsius exhibits a pressure of 740 torr and occupies a volume of 4.42 L.

a)Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.85 atm while the temp is held constant.

b)Use Charles's law to calculate the volume the gas will occupy if the temperature is increased to 160 degrees Celsius while the pressure is held constant.

3.A scuba diver's tank contains 0.29 kg of O2 compressed into a volume of 2.3 L.

a)Calculate the gas pressure inside the tank at 9 degrees Celsius.

b)What volume would this oxygen occupy at 25 degrees Celsius and 0.94 atm?

and

4. Calculate the rms speed of NF3 molecules at 21 degrees Celsius.
