If a liquid is sealed in a container and kept constant temperature how does its vapor pressure change over time?
If a liquid is sealed in a container at a constant temperature, its vapor pressure will initially increase until it reaches a steady state, known as equilibrium. At this point, the rate of evaporation of the liquid equals the rate of condensation of the vapor, resulting in a constant vapor pressure. Once equilibrium is achieved, the vapor pressure remains stable over time, as long as the temperature remains constant and no additional liquid is added or removed.

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.
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
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 change will not affect the pressure in a container?
Changing the color of the container will not affect the pressure inside it. Pressure is determined by factors such as temperature, volume, and the number of gas molecules present, not by the container's color.
What happens when pressure falls and temperature rises?
Temperature is really just the amount of kinetic energy in the molecules of a substance. If you add more energy by heating the substance then the molecules dash about faster and faster. This increases the pressure if the substance is constrained, like gas in a jar or in a bomb.

How does the pressure of a container change as the volume is changed?
According to Boyle's Law, the pressure of a gas in a container is inversely proportional to its volume when temperature is constant. This means that as the volume of the container decreases, the pressure of the gas inside will increase, and vice versa.
Raising temperature of a gas fixed volume container will change?
The pressure of the gas inside the container will increase due to the increased kinetic energy of the gas molecules. This is described by the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
What ideal gas is stored in a container at constant volume. If the temperature (T) were increased to 3T what would be the change in pressure (P)?
The ideal gas law states that pressure (P) is directly proportional to temperature (T) at constant volume. So if the temperature is increased to 3T, the pressure would also increase by a factor of 3.

How do conditions change inside a rigid container when you use a pump to add gas to the container?
When gas is added to a rigid container using a pump, the pressure inside the container will increase due to the increase in the number of gas molecules colliding with the container walls. The temperature inside the container may also increase slightly due to the compression of the gas. The volume of the gas in the container will remain constant since the container is rigid and unable to expand.
What is the formula for calculating the change in pressure when the volume and temperature of a gas are held constant?
The formula for calculating the change in pressure when the volume and temperature of a gas are held constant is: P (nRT/V)T, where P is the change in pressure, n is the number of moles of gas, R is the gas constant, T is the temperature, V is the volume, and T is the change in temperature.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
Yes, the frequency of a wave remains constant as long as the medium temperature and pressure do not change. Temperature and pressure affect the speed of sound in a medium, not the frequency of the wave.
What usually happens in general for a gas at a constant volume?
The gas volume become constant when the pressure is increased to a point that makes the distance between the gas molecules equal to zero at this point no more increase of temperature with pressure is observed. Or if the pressure and temperature are kept constant within a system then the volume can also be constant as long as you are able to maintain the pressure and temperature at constant level.
How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.
What happens to the pressure of a gas inside a rigid container if the temperature of the gas temperature of the gas decreases?
Cooling a pressurized container will cause the internal pressure to decrease.This works in reverse too. Depressurizing a pressurized container will lower the internal temperature (and by conduction, the temperature of the container itself). This is why ice often forms around propane gas cylinders after extended use.
