The temperature
There is a clear relationship between volume and pressure, but it's actually inversely proportional instead of directly proportional. If we apply pressure to a balloon (squeeze it), the volume goes down and the balloon takes up less space. In other words, increasing the pressure decreases the volume. For ideal gasses, it's a completely inverse relationship expressed by Boyle's Law which says that the product of the pressure and volume is always constant. So if one increases, the other has to decrease.
The number of gas molecules in the sample is directly proportional to the pressure exerted by a gas on its container.
atmosheric pressure
temperature
the pressure of the gas is directly proportional to its temperature in Kelvin e2020 lol
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.
directly proportional to the Kelvin temperature
that the temperature of a gas is directly proportional to its volume at constant pressure. In other words, if you increase the temperature of a gas, its volume will also increase.
There are three main gas laws: Boyle's, Charles' and the pressure law. These describe the relationship between pressure, volume and temperature of an ideal gas. Boyle's law: the volume of a gas is inversely proportional to its pressure; i.e. doulbing the pressure applied to a gas will halve the volume it takes up (and vice-versa). Charles' law: the volume of a gas is directly proportional to its temperature; i.e. doulbing the temperature of a gas will double the volume it takes up (and vice-versa). Pressure law: the pressure of a gas is directly proportional to its temperature; i.e. doubling the temperature of a gas will double the pressure placed upon the gas (and vice-versa). These three laws can be combined with another to give the ideal gas law: PV = nRT (where P = pressure, V = volume, n = number of moles, R = universal gas constant and T = temperature in Kelvin). But seriously, next time, just Google it - it'll be faster. Or maybe read a textbook?
Directly proportional, at pressure and temperature constant.
Inversely proportional means that one variable goes up while the other goes down. Directly proportional means that both variables increase or decrease at the same time. ex: The volume of a gas at constant pressure is inversely proportional to gas pressure, thus this means that as pressure increases, the volume of the gas will decrease. ex: The volume of a fixed amount of gas is directly proportional to absolute pressure, thus this means that when you heat a gas the volume also increases.
Lots of things are true... Here are some:* For constant pressure, the volume of an ideal gas is directly proportional to the absolute temperature. * For constant volume, the pressure of an ideal gas is directly proportional to the absolute temperature.
The volume of a gas is not directly proportional to its molecular weight.
volume and amount of a gas.
the pressure of the gas is directly proportional to its temperature in Kelvin e2020 lol
the pressure and temperature are held constant. ideal gas law: Pressure * Volume = moles of gas * temperature * gas constant

Charles' Law. The volume and absolute temperature of a gas are directly proportional when pressure is constant.
At a constant temperature, the amount of a given gas that dissolves in a given type and volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid.
all gases. The volume of a gas is directly proportional to the temperature, and inversely proportional to pressure. Maybe you mean air, but air is a mixture of gases
The temperature, pressure, and volume of gases can be related by the ideal gas equation. PV = nRT where P is pressure, V is volume, n is moles, R is that ideal gas constant, and T is the temperature in Kelvin.
