Since temperature is related to air pressure. As the sun heats the ground or ocean, warning them, the air near the ground or ocean warms and becomes less dense. As this happens the air begins rising, which lowers the air pressure at the Earth's surface. In detecting atmospheric pressure, a barometer measures the weight of the column of air that stretches directly above it from the Earth's surface to the top of the atmosphere. If air pressure goes up, this means that more air molecules are moving into that column of the atmosphere than are leaving it. Essentially, this "piling on" of air molecules increases air density, makes the column of air heavier and causes it to sink resulting in higher atmospheric pressure. Cold air entering a region would cause pressure to rise.

∙ 13y agoWhen gas particles are heated they gain energy so they start moving faster and faster. This causes them to spread out and rise.

When a sample of gas is heated what happens to the motion of the particles?
The motion of particles is accelerated.
What happens to the particles in a liquid when it is heated?
They begin to vibrate more quickly when a liquid is heated, it will evaporate. ie. the liquid will turn to vapour (gas). if the vapour i s collected, it will turn back to the liquid again once it is cooled (condensation) muck love, kate
How do particles move when they are heated?
Particles move faster when they are heated.
What are particles in a gas are best described as?
Because the particles of the gas are in a state (sometimes called an excitable state) which allows random movement, they are vibrating and continually bouncing against each other, and moving faster if the gas is heated. Smoke rises from a fire because it is heated. Since the hotter particles are hitting their neighbours harder and faster the gas needs to take up more space. It expands. It also becomes lighter or less dense. it begins to rise, forming convection currents. Warm air rises; cold air sinks.
Do molecules rise or sink after they are heated?
Rise
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.
How does that speed of the particles of a gas change when the gas is heated?
When gas is heated then its molecule get energy and start to move faster.
What is the process in which water changes from a liquid to a gas called?
evaporation. the water particles get heated up and they rise into the sky and build up. then we have rain storms
When a sample of gas is heated what happens to the motion of the particles?
The motion of particles is accelerated.
When heated bubbles rise to surface?
bubbles rise to the surface of a heated liquid as it changes to gas because they are less dense than the liquid.
What happens to the particles ina gas went they are heated?
The particles start moving faster and the matter expands.
What happens to the particles in a liquid when it is heated?
They begin to vibrate more quickly when a liquid is heated, it will evaporate. ie. the liquid will turn to vapour (gas). if the vapour i s collected, it will turn back to the liquid again once it is cooled (condensation) muck love, kate
Do gas particles vibrate while they move?
Not to my knowledge, they only vibrate if they are heated
Do gas particles speed up or slow down when heated?
They speed up.
What does the particle theory suggest about the motion of the particles of solids-liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
What does the particle theory suggest about the motion of the particles of solids liquids and gases when they are heated?
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
Why does a gass expand when heated and contract when cooled?
When a gas is heated up, the particles within the gas start to move faster, going farther apart (expansion). When a gas is cooled, the particles slow down and it starts to condense (contract), and if cooled enough, into a liquid.
