# Why does gas expand to fill a container?

## Why do gases expand to fill a container?

Gases move in rapid motion and collide with one another. This means that momentum and energy are transferred and not lost during collisions. Rapid motion refers to gases expanding spontaneously to fill any container. Brownian motion (rapid movement) of smoke particles

### Should a gas have a higher pressure when it is in a small container or a large one?

Boyle’s law An increase in space will allow gas particles to spread further apart. However, this decreases the number available for them to collide with each other, so pressure drops. The pressure rises when the container’s volume is reduced. This forces the particles to collide more frequently.

#### What has more volume gas or liquid?

If you have the same amount of particles, the gas will have a greater volume. Although the particles of matter in liquid are still very close, they are far enough apart that they can move freely. The gaseous state of matter particles are not as close to each other nor in fixed place.

How do you increase the temperature of a gas?

Adding more molecules to a gas causes collisions between them and the walls of the container. This increases pressure. This will raise the temperature of gas.

What happens if we remove heat from water at 0 C does the temperature change?

c. Water’s boiling point temperature will not change. What happens if heat is removed from water at 0degC The water’s temperature will drop.

## Does melting absorb or release energy?

Note that melting and vaporization can be considered endothermic because they require energy to absorb and produce it, while freezing or condensation are exothermic as they are energy-releasing processes.

### When water freezes is heat absorbed or released?

Water freezes and releases some of its energy. The latent heat of frost is this energy. The latent heat of the freezing process was occurring when the water was frozen. In fact, heat energy was being released.

#### How much heat did the water absorb?

Water’s most important property is its ability to absorb a lot heat to make it hot. Precisely, water has to absorb 4,184 Joules of heat (1 calorie) for the temperature of one kilogram of water to increase 1degC. For comparison sake, it only takes 385 Joules of heat to raise 1 kilogram of copper 1degC.
