What happens to the pressure of a gas when it is heated and why?

When things are heated, the molecules become "excited" This excitement translates into expansion. When cooled the excitement diminishes, causing things to contract.
Basically the same for solids and non-solids. Different things have different degrees of expansion and contraction. Railroad tracks have been known to buckle, and concrete roads have also been known to "explode" when over heated. Bolts work themselves loose on bridges because of changes in heat and cold. ( exacerbated by movement vibration )

∙ 10y agoWhen heated the molecules are moving faster, so they bump more often against the container wall (or against each other) and that's just what pressure is!

What happens to nitrogen liquid when heated?
There will be a high pressure explosion...within the evaporated gas from the liquid and the heat..
How does gas affected when air is heated?
If the question is "How IS gas affected when it is heated":When gas is heated, it's volume increases (it expands).If the gas is contained within a chamber, the pressure will increase instead.
What happens to a gas's mass when it is heated?
The atoms in the mass become more energetic and create more pressure. If the bounds of the container allows it, such as in a balloon, the gas will expand. If the bounds doe not allow it, such as in a fixed container, the pressure will increase.
what happens to a gas as pressure is reduced?
When the pressure of a gas is reduced it gets colder.
What happens to the entropy of gas as it is heated?
In a closed system the entropy is constant.
What happens to the pressure of gas when it is heated and why?
The molecules of a gas move faster when heated so the pressure increases.
What happens to the pressure of gas when it is heated at a constant heat?
The pressure is higher.
What happens when gas is heated?
it expands and/or its pressure rises, depending on conditions.
What happens to the speed of gas when heated?
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.
What happens when a gas is heated beyond 100 degrees?
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.
What happens to a gas when you heated?
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.
What happens to gas in a balloon when that gas is heated?
The gas will expand as it is heated.
What happens to nitrogen liquid when heated?
There will be a high pressure explosion...within the evaporated gas from the liquid and the heat..
What happens to a gas heated in cylinder?
the gas expands and exerts more pressure on the sides of the cylinder. Basically, the pressure goes up due to a temperature increase.
What is a gas that expands when heated?
Any gas will expand when heated, assuming you keep pressure constant.
What happens the air when it is heated by the sun?
Like any other gas, air expands when it is heated. As the heat rises and the air spreads out, pressure decreases. this because pressure is the amount of force exerted on a specific area. Therefore, as gas spreads, it pushes less and over a larger area. so.... when heated by the sun, air pressure would technically decrease
