The temperature of a gas in a sealed container changes from 20.0C to 40.0C if the volume remains constant the pressure will change from 660 torr to?
330
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
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 volume of a gas change when it's temperature is increased at constant pressure?
The volume decreases
How do gases behave in a closed container?
Since you have specified a closed container, the amount of gas doesn't change, and the volume that it occupies doesn't change. The only thing that is likely to change is the temperature, and changes in temperature will cause corresponding changes in pressure. And if the pressure gets too high, your closed container is going to explode. So avoid overheating.

How do conditions change inside a rigid container when you use a pump to add gas to the container?
Rigid container implies the volume stays constant. The pressure will increase, and if the container is well insulated, the temperature may also increase.
Raising temperature of a gas fixed volume container will change?
it would change the pressure exerted by the gas in the container.
What must the temperature be for the gas to remain at a constant pressure?
"Constant pressure" means the pressure must not change.
What will increase the volume of gas?
change the pressure and/or the temperature of the gas
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.
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.
What causes a gas to exert pressure when confined in a container?
Assuming constant amount of gas and temperature, pressure will increase as volume decreases. Conversely, pressure will decrease as volume increases. If you squeeze on a filled balloon, the volume decreases. The pressure of the air on each square inch of the balloon increases, which causes it to eventually pop if the pressure gets too high. Assuming constant amount of gas, a temperature change will already change the volume of the gas. As temperature rises, the gas expands, causing more pressure to be exerted on the balloon. Assuming constant temperature, adding more gas also increases the volume and thus increases the pressure.
When scientists record the volume on a gas why do they also record the temperature and the pressure?
because the volume of the gas is dependent upon the temperature and pressure. This is also important in the identification of the molecular mass of an unknown gaseous element.
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.
Does the frequency of a wave remain constant if the medium temperature and pressure do not change?
no
