Pressure - Volume Relationship

Boyle's law states that when the temperature of a gas is kept constant, the volume of a fixed mass of gas is inversely proportional to its pressure. 

What type of graph is obtain when pressure is plotted against volume? 

According to Boyle’s law, the volume of a gas is inversely proportional to its pressure at a constant temperature.

The plot of volume versus pressure at constant temperature is _____. (hyperbola/parabola)

When a large bubble rises from the bottom of a lake to the surface, its radius doubles. If atmospheric pressure is equal to that of a column of water of height $\mathrm{H}$. The depth of the lake is

Graphs between pressure and volume are plotted at different temperatures. Which of the following isotherms represents Boyle's law as PV = constant?

A gas at the temperature $250\mathrm{ K}$ is contained in a closed vessel. If the gas is heated through $1\mathrm{ K},$ then percentage increase in its pressure will be
