The pressure P (in kilopascals), volume V (in liters), and temperature T (in kelvins) of a mole of an
ideal gas are related by the equation PV = 8.31T. Find the rate at which the volume is changing
when the temperature is 270 K and increasing at a rate of 0.2 K/s and the pressure is 28 and
increasing at a rate of 0.08 kPa/s.

In an ultrahigh vacuum system (with typical pressures lower than 10-7 pascal), the pressure is measured to be 1.00 x 10-10 torr (where 1 torr = 133 Pa). Assuming the temperature is 310 K, find the number of molecules in a volume of 1.00 m3.
A (1.0x10^1) liter bottle is filled with nitrogen (N2) at STP (Standard Temperature and Pressure is 1 atm and 273 K) and closed tight. If the temperature is raised to 100° C, what will be the new pressure in SI units to two significant figures.
