Pressure is used to increase the volume of gas

Pressure is used to increase the volume of gas in Boyle's law.

Angelo noticed his lab partner had incorrectly recorded the pressure of a gas in mmHg rather than in atmospheres as their teacher requested When he corrected the mistake Angelo recorded 751.5 mmHg

the answer is 0.99 :)

Chen-liu has a sample of chlorine in a 10.00ml container at 25.00 and 0.9840 ATM if the gas is compressed to a volume of 7.600ml the temperature will rise to 26.00c and the resulting preassure will b

The resulting pressure will be 1.298 atm.
