When a Gas Expands at a Constant Temperature Its Pressure $40 \mathrm{~kg} / \mathrm{m}^{2}$

Short Answer

When a gas expands at a constant temperature its pressure varies inversely as its volume. If the pressure of a certain gas is $40 \mathrm{~kg} / \mathrm{m}^{2}$ when its volume is $0.8 \mathrm{~m}^{3}$ , determine the pressure when the volume of the gas is $0.1 \mathrm{~m}^{3}$ ?
