# Relationship between pressure and volume of air

### Boyle's law - Wikipedia

Short answer: The general relationship between pressure and volume is an inversely proportional one. This means that if everything else remains the same, . All of these questions have to do with the volume of air and the relationship between air pressure, temperature and volume. And yes, they are. It is these collisions between the particles of the gas and the walls of the container it The relationship of a gas with pressure and volume was developed by the.

A more convient unit is the torr. A torr is the same unit as the mmHg millimeter of mercury. It is the pressure that is needed to raise a tube of mercury 1 millimeter. The Pressure-Volume Law Boyle's law or the pressure-volume law states that the volume of a given amount of gas held at constant temperature varies inversely with the applied pressure when the temperature and mass are constant.

Another way to describing it is saying that their products are constant. When volume goes up, pressure goes down.

## What’s the relationship between pressure and volume of gas?

From the equation above, this can be derived: This equation states that the product of the initial volume and pressure is equal to the product of the volume and pressure after a change in one of them under constant temperature. For example, if the initial volume was mL at a pressure of torr, when the volume is compressed to mL, what is the pressure?

Plug in the values: The Temperature-Volume Law This law states that the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature. V Same as before, a constant can be put in: Also same as before, initial and final volumes and temperatures under constant pressure can be calculated.

### What’s the relationship between pressure and volume of gas? - Core Concepts in Chemistry

Air Pressure and Volume: Boyle's Law Boyle's Law defines the relationship between a gas volume and its pressure. If you take a box full of air and then press it down to half its size, the air molecules will have less space to move around and will bump into each other much more.

These collisions of air molecules with each other and with the sides of the container are what create air pressure.

Sciencing Video Vault Boyle's Law doesn't take temperature into consideration, so the temperature must be constant in order to use it. Boyle's Law states that, at a constant temperature, the volume of a certain mass or amount of gas varies inversely with the pressure.

### Relationships among Pressure, Temperature, Volume, and Amount

In equation form, that's: Suppose you're designing a scuba tank where the air pressure is psi pounds per square inch and the volume or the "capacity" of the tank is 70 cubic feet. If you decide you'd rather make a tank with a higher pressure of psi, what would the volume of the tank be, assuming you fill it with the same amount of air and keep the temperature the same? Plug the given values into Boyle's Law: Air Temperature and Volume: Charles' Law What about the relationship between volume and temperature?

Since density is mass over volume, and the mass stays constant, the rise in density means that the volume of the balloon decreases: For two states of pressure P1, P2 and two corresponding volumes V1, V2this is stated mathematically: This in turn increases the rate at which the gas molecules bombard the skin of the balloon. Cooling the balloon down again will make the balloon shrink.

For two states with temperatures T1, T2 and two corresponding volumes V1, V2: It must be noted that in this case and whenever temperature appears in a multiplication or a division the absolute or Kelvin scale must be used for temperature.
