A principle of physics stating that the product of pressure and volume divided by the temperature is a constant for an ideal gas. It is a good approximation for many real gases, such as helium, over reasonable ranges of temperature and pressure.

The pressure of a ideal gas is inversely proportional to its volume, if the temperature and amount of gas is held constant. Doubling gas pressure halves gas volume, if temperature and amount of gas do [..]

When the temperature is held constant, the pressure and density of an ideal gas are directly proportional.

The volume of a dry gas varies inversely with the pressure exerted upon it, provided the temperature is constant.

The pressure of an ideal gas is inversely proportional to the volume of the gas at constant temperature.

The pressure and volume of a gas at a constant temperature are inversely proportional to each other. (Lesson 6)

PV = k, where P is pressure, V is volume and k is a constant. Means that if pressure decreases (such as during an ascent) then the volume of gas increases (assuming temperature is constant). And vice [..]

the volume of a given mass of gas held at constant temperature is inversely proportional to the pressure under which it is measured. PV = k.

A scientist named Robert Boyle came up with an understanding of the way pressure and volume are related (at constant temperatures). His formula shows that the volume of a gas is inversely proportional [..]

A fundamental law in the behavior of ideal gases: if temperature is kept constant, the density D of a gas varies proportionally to its pressure P. Actual gases usually approximate ideal ones pretty we [..]

At constant temperature, the volume of a fixed amount of gas is inversely proportional to pressure.

States that when the temperature is held constant, the volume of a gas is inversely proportional to its pressure. Therefore, if the pressure increases, the volume decreases and visa versa. For example, if the volume if halved, then the pressure is doubled. If the temperature is held constant, it becomes an isothermal process. Discovered by Robert B [..]
