Heating a gas in a closed container would increase it's pressure. This would happen because when you heat the gas, the particles' kinetic energy increases, making them move faster, and more. They will hit the sides of the container and create pressure.
As you heat any matter you increase the kinetic energy the particles of that matter have. An increase in kinetic energy means that the particles move more and take up more space. This is manifested as an increase in pressure for gases in an enclosed container.
Neither rigid nor initially are synonyms for worse.
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.
The rigid layer that is the upper mantle and crust is called the lithosphere.
Rigid container implies the volume stays constant. The pressure will increase, and if the container is well insulated, the temperature may also increase.
Given that the container is "rigid" the size of the container holding the gas cannot change. Since the volume of the container remains constant, so too does the volume of the gas. The pressure however will increase.
Increasing the number of moles of gas, decreasing the volume of the container, or iIncreasing the temperature could cause a rigid container of gas to explode.
Solids are rigid and incompressible. Liquids have fixed volume but match their container. Gases completely fill their container.
A bucket is a rigid container, often with a handle, used to carry liquid or small items, or the contents of this container.
A blimp is an airship constructed with a non-rigid lifting agent container.
It doesn't change
Yes, it is true.
because solid are rigid while liquid are not
a rigid substance that doesn't take the shape of its container.
No, because the gas is in a rigid steel container, its volume cannot increase as the temperature increases (assuming the steel does not deform). Instead, the pressure of the gas inside the container will increase. Of course, if the pressure is high enough, the container will explode, lowering the pressure and causing the gas to expand.
It is true that, in a rigid container, when the speed of the gas molecules increases, the temperature of the gas rises. This has nothing to do with the speed or lack of speed of the gas as a whole.
