If the pressure and temperature of a gas are held constant and some gas is added to the container or some is allowed to escape a change is can be observed?
If the pressure and temperature of a gas are held constant and gas is added or removed from the container, the volume of the gas will change according to Boyle's Law. Adding gas will increase the volume, while escaping gas will decrease it. This relationship is governed by the ideal gas law, where the volume is directly proportional to the number of moles of gas when pressure and temperature remain unchanged. Therefore, any change in the quantity of gas affects the volume of the gas in the container.
What else can I help you with?
If a liquid is sealed in a container and kept at constant temperature how does its vapor pressure change over time?
If a liquid is sealed in a container and kept at a constant temperature, its vapor pressure will initially increase until it reaches a constant value, known as the equilibrium vapor pressure. At this point, the rate of evaporation of the liquid equals the rate of condensation of the vapor, resulting in no further change in vapor pressure over time. This equilibrium is maintained as long as the temperature remains constant and the container remains sealed.
Explain why increasing the temperature of a gas in closed rigid container causes the pressure in the container to increase?
Because the pressure increases The real answer is: Charles's Law. He found that if you increase the temperature of a constant pressure the volume increases also.
If you wanted to predict how temperature will effect the volume of a gas what factors must be held constant?
If temperature increases, then pressure increases. Temperature measures the average speed of particles, so if the temperature is high, then the particles are moving quickly and are colliding with other particles more forcefully. Pressure is defined as the force and number of collisions the particles have with the wall of its container. So if the high temperature causes the particles to move quickly, they are going to collide more often with the container, increasing the pressure. This remains true as long as the number of moles (n) remains constant.
What would the effect on temperature and volume be if you changed the number of moles of gas in a container?
In a container the volume remain constant but the pressure increase.
When a container decreases in size what will happen to an amount of gas in the container?
If the container decreases in size, the pressure inside the container will increase. This is because the gas molecules are more confined and collide more frequently with the walls of the container. The amount of gas remains constant, but the pressure changes due to the reduced volume.
When gas in a container expand to twice its volume at constant temperature the gas pressure does what?
If the volume of a gas doubles at constant temperature, the pressure of the gas decreases by half according to Boyle's Law. This is because pressure is inversely proportional to volume in a closed system at constant temperature.
What is the temperature if the gas pressure is constant?
At isobaric (pressure) expansion (volume increase) the temperature will increase because V is proportional to T for the same amount of gas (closed container) at constant pressure.
If the volume of a container of air is reduced?
If the volume of a container of air is reduced, the pressure of the air inside the container will increase. This is because the volume and pressure of a gas are inversely proportional according to Boyle's Law. The particles inside the container will collide more frequently with the walls, leading to an increase in pressure.
If a liquid is sealed in a container and kept at constant temperature how does its vapor pressure change over time?
If a liquid is sealed in a container and kept at a constant temperature, its vapor pressure will initially increase until it reaches a constant value, known as the equilibrium vapor pressure. At this point, the rate of evaporation of the liquid equals the rate of condensation of the vapor, resulting in no further change in vapor pressure over time. This equilibrium is maintained as long as the temperature remains constant and the container remains sealed.
When does raising the temperature of gas increase its pressure?
Raising the temperature of a gas increases its pressure when the volume of the gas is kept constant. This is described by the ideal gas law, which states that pressure is directly proportional to temperature when volume is constant. When the temperature of a gas is increased, the average kinetic energy of the gas particles increases, leading to more frequent and forceful collisions with the walls of the container, resulting in higher pressure.
What would happen to the pressure of a gas sealed container if the volume increases and the temperature stays the same?
If the temperature increases, then the volume of the gases cannot stay the same. The pressure will keep building until it overcomes the integrity of the container its contained in and causes an explosion.
Explain why increasing the temperature of a gas in closed rigid container causes the pressure in the container to increase?
Because the pressure increases The real answer is: Charles's Law. He found that if you increase the temperature of a constant pressure the volume increases also.
What will cause a decrease in a gas pressure in a closed container?
A decrease in temperature or a decrease in the number of gas molecules in the container will cause a decrease in gas pressure. Alternatively, if some of the gas molecules escape from the container, the pressure will also decrease.

In a container the volume remain constant but the pressure increase.
If the temperature of gas in the container decreases what happens to its pressure?
Assuming the volume is kept constant, the pressure will also decrease in this case.
What happens when solute particles are added to a pure solvent in a closed container at a constant temperature and pressure?
it decreases.
