Explain the phenomenon of collision broadening of spectral lines.

 If I have 17.0 liters of gas at a temperature of 67.0 °C and a pressure of 88.89 atm, what will be the pressure of the gas if I raise the temperature to 94.0 °C and decrease the volume to 12.0 L?(round to correct sig figs)

 I have an unknown volume of gas at a pressure of 0.50 atm and a temperature of 325 K. If I raise the pressure to 1.2 atm, decrease the temperature to 320 K, and measure the final volume to be 48 liters, what was the initial volume of the gas? (round to correct sig figs)

If I have 21 liters of gas held at a pressure of 78 atm and a temperature of 900. K, what will be the volume of the gas if I decrease the pressure to 52 atm and decrease the temperature to 750 K? (round to sig figs)

If I have 2.9 L of gas at a pressure of 5.0 atm and a temperature of 50.0 °C, what will be the new temperature if I decrease the volume of the gas to 2.4 L and decrease the pressure to 3.0 atm(round to correct sig figs)

I have an unknown volume of gas held at a temperature of 115 K in a container with a pressure of 60atm. If by increasing the temperature to 225 K and decreasing the pressure to 30. atm causes the volume of the gas to be 29 liters, how many liters of gas did I start with? (round to correct sig figs)
