# When you hit a gas What happens to the particles?

## When you hit a gas What happens to the particles?

When you heat a gas, both its vapor pressure and the volume it occupies increase. The individual gas particles become more energetic and the temperature of the gas increases. At high temperatures, the gas turns into a plasma.

## Why are both liquids and gases called fluids?

A gas fills its container, taking both the shape and the volume of the container. Liquids and gases are called fluids because they can be made to flow, or move. In any fluid, the molecules themselves are in constant, random motion, colliding with each other and with the walls of any container.

When you see steam fog or clouds you are seeing water in the gas state?

Term What are the three “familiar” states of matter? Definition Solids, Liquids, and gases
Term TRUE/FALSE? When you see steam,fog, or clouds, you are seeing water in the liquid state. Definition True

### Is the force of its outward push over an area of the walls of a container?

Gas pressure is the force of its outward push divided by the area of the walls of its container. As the moving gas molecules collide with the walls of their container, they push on the container walls.

### What is not a fluid?

The word fluid means- a substance that flows, changes shape, non-rigid and has no distinctive shape. As the solid materials do not do any of the mentioned above, they are not called fluids.

What is vaporization the reverse of?

Vaporization is the reverse of condensation. 17. The temperature at which a liquid turns to a gas is called the boiling point.

#### When a gas turns to a liquid the energy of the particles?

When a gas turns to a liquid (condenses) or a liquid turns to a solid (solidifies) the particles lose energy to the surroundings.

#### What happens when particles in a gas lose enough thermal energy to form a liquid?

Condensation occurs when particles in a gas lose enough thermal energy to form a liquid. Clouds typically form when water vapor in the atmosphere condenses into tiny liquid droplets.

What is caused by gas particles colliding with the walls of their container and pushing them outward?

Gas particles colliding with the walls of their container causes gas pressure. The higher the temperature, the faster gas particles move. The faster gas particles move,the more frequently they collide with the walls of their container and the greater the pressure will be.
