A sample of ammonia gas with a volume of 7.0 mL at a pressure of 1.68 atm is compressed to a final volume of 2.7 mL at constant temperature. Use the ideal gas law to calculate the final pressure.
a. 100 atm
b. 2.2 atm
c. 1 atm
d. 4.4 atm

Does the pressure of a gas increase or decrease when its temperature is INCREASED but the volume is CONSTANT (like when you apply heat to a can of hair spray) and explain why.
Ideas are expressed.

The problem is this....
