Boyle's law states that the
a. volume of a gas varies inversely with pressure.
b. volume of a gas varies directly with pressure.
c. temperature of a gas varies inversely with pressure.
d. temperature of a gas varies directly with pressure.

The correct answer is A. The volume of a gas varies inversely with pressure. Boyle's law is one of the gas laws we have. According to this law, at a fixed amount of an ideal gas which is at constant temperature, the pressure and volume are inversely proportional with each other.
