Two containers of equal volume each hold samples of the same ideal gas. Container A has 2 times as many molecules as container B. If the gas pressure is the same in the two containers, find the ratio of the the absolute temperatures TA and TB ( i.e  TA / TB  ) . Calculate to 2 decimals.

A gas is in a sealed container. The gas pressure is tripled and the temperature is doubled. By what factor does the number density of the gas increase?

Suppose that the temperature at a point x, y, z in space is given by T(x,y,z)=80/1+x2+2y2+3z2, where T=°c and x,y,z in metres. In which direction does the temperature increases fastest at the point (1,1,-2). What is the maximum rate of increase.
