PLEASE HELP urgently!!!
1.The initial volume of a gas at a pressure of 5 atm is 3.5 L. What will the volume be if the pressure is increased to 6 atm?

Include units.

2. A gas is contained in a 4 L container at a pressure of 2 atm. The container is at a temperature of 15 degrees Celsius. What will the pressure be if the temperature is increased to 30 degrees Celsius?

Include units.

3. Calculate the decrease in temperature when 6.00 L of gas at 20.0 °C is compressed to 4.00 L.

Include units.

4. A 40.0 L tank of ammonia has a pressure of 5.5 atm. Calculate the volume of the ammonia if its pressure is changed to 8.2 atm while its temperature remains constant.

5. Determine the pressure change when a constant volume of gas at 1.5 atm is heated from 18 °C to 32 °C.
