What happens to the volume of a gas if the pressure doubles?

FIGURE 9.8 Boyle’s Law: At constant temperature, the volume of a gas sample is inversely proportional to the pressure. If the pressure on the piston is doubled, the volume of the gas decreases by one-half.

What happens to the pressure of a gas if you increase the volume?

Decreasing the volume of a contained gas will increase its pressure, and increasing its volume will decrease its pressure. In fact, if the volume increases by a certain factor, the pressure decreases by the same factor, and vice versa.

What happens to the volume of a gas when temperature and pressure is doubled?

The volume is directly proportional to the temperature and inversely proportional to the pressure. And if the temperature is doubled, the volume increases to twice the original volume.

What would cause the pressure of gas to double?

The kinetic energy causes the air molecules to move faster and they impact the container walls more frequently and with more force. The kinetic energy of the gas molecules increases, so collisions with the walls of the container are now more forceful than they were before. As a result, the pressure of the gas doubles.

What happens when the pressure of a gas is lowered?

The combined gas law states that the pressure of a gas is inversely related to the volume and directly related to the temperature. If temperature is held constant, the equation is reduced to Boyle’s law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase.

What happens to the pressure of a gas when the temperature increases?

The temperature of the gas is proportional to the average kinetic energy of its molecules. Faster moving particles will collide with the container walls more frequently and with greater force. This causes the force on the walls of the container to increase and so the pressure increases.

What do you expect to happen to a gas volume if its pressure is doubled and its temperature is reduced to half?

Since pressure x volume remains constant, for example, doubling the pressure on an enclosed gas will reduce its volume to 1/2 its previous size. If you trap gas in a cylinder, and then reduce the internal volume of the cylinder to half its original value, the pressure will double.

When a gas is under pressure its volume?

Robert Boyle, a chemist and physicist from the 17th century, discovered that the volume of gas, meaning how much space it occupies, is related to its pressure—and vice versa. He found that if you pressurize a gas, its volume contracts. If you decrease its pressure, its volume increases.

What happens to volume when pressure decreases?

when the pressure of gas is decreased, the volume increases. this relationship between pressure and volume is called Boyle’s law. So, at constant temperature, the answer to your answer is: the volume decreases in the same ratio as the ratio of pressure increases.
