a gas occupies a volume of 50.9ml at 27C and 630 mmhg . at what temperature, in C , would the pressure be 101.3 mmhg if the volume remains constant?

If a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?

What are some natural measures of time
