the gas expands and exerts more pressure on the sides of the cylinder. Basically, the pressure goes up due to a temperature increase.
When heat is applied to a gas contained in a cylinder, the gas molecules gain kinetic energy and move faster. This increase in speed causes the gas to expand, increasing its volume and pressure inside the cylinder. If the cylinder is sealed, the pressure will build up until the gas escapes or the cylinder bursts.
Heating will cause the gas to expand; or, if the container does not permit expansion, for the pressure of the gas to increase. Other changes to the gas depend on which gas is being heated.
evaporate
The gas molecules receive kinetic energy and start to vibrate
A heated liquid become a gas at the boiling point.
they turn into gas
If the gas is compressed into the cylinder, yes. However if the gas is already pre-compressed (to the point of liquefaction) and simply decanted into the cylinder, there will be little to no heating of the receptacle cylinder.
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.
they tend to vibrate
The pressure is higher.
Decomposed to produce PbO and oxygen gas!
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.
