Applying heat to a gas will make it expand. If the volume of the gas is restricted (i.e. it cannot expand) then the pressure will increase.
they turn into gas
It moves Faster.
When a noble gas is heated, its molecules move faster (this is the same as saying that the gas heats up).
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
it expands and/or its pressure rises, depending on conditions.
Decomposed to produce PbO and oxygen gas!
they tend to vibrate
The pressure is higher.
The main type of thermal energy transfer that happens when a gas is heated is convection. In convection, the heated gas molecules become less dense and rise, while cooler gas molecules sink, creating a circular motion that transfers heat throughout the gas.
The water gets heated up and turns into a gas
When the gas in a balloon is heated, its temperature increases, causing the gas molecules to move faster and collide more frequently with the walls of the balloon. This increases the pressure inside the balloon, which causes the balloon to expand as it attempts to accommodate the increased volume of gas.
Its particles acquire greater kinetic energy.
