## What is it called when a liquid turns into a gas?

Evaporation occurs when particles in a liquid pass directly into the gas state, at a temperature below the boiling point of the liquid. Evaporation is dependent on individual particles gaining enough energy to escape the surface of the liquid and become gas particles.

## When a liquid increases in temperature and becomes a gas it is called?

Vaporization of a sample of liquid is a phase transition from the liquid phase to the gas phase. There are two types of vaporization: evaporation and boiling. Evaporation occurs at temperatures below the boiling point, and occurs on the liquid’s surface.

What temperature does gas become a liquid?

The linear (straight line) part of the graph represents ideal gas behavior—volume and temperature are directly and positively related and the line extrapolates to zero volume at –273.15ºC, or absolute zero. When the gas becomes a liquid, however, the volume actually decreases precipitously at the liquefaction point.

How a liquid becomes a gas?

The process of a liquid becoming a gas is called boiling (or vapourization), while the process of a gas becoming a liquid is called condensation. This means that the temperature at which a liquid becomes a gas, the boiling point, can change with surrounding pressure.

### How the liquid pressure differs from gas pressure?

Pressure within a liquid depends only on the density of the liquid, the acceleration due to gravity, and the depth within the liquid. Pressure within a gas depends on the temperature of the gas, the mass of a single molecule of the gas, the acceleration due to gravity, and the height (or depth) within the gas.

### Is pressure on gas and liquid the same?

The pressure only depends on the number and speed of the impacts – so only on the amount of gas and it’s temperature. In a liquid the molecules near the walls push against the wall and are pushed by the other molecules above/behind them.

How does a gas turn into a liquid?

The process of a gas changing to a liquid is called condensation, and for condensation to take place, the environment has to reach maximum vapor pressure, generally through a lowering of temperature in the case of the water cycle. Because pressure varies inversely with temperature, as temperature decreases,…

What’s the pressure at which natural gas becomes liquid?

Natural gas is usually 80+ percent by volume methane. Considering just methane we have the following phase diagram: At -160 C or so, increasing the pressure to 0.1 atm or above would convert the gas to liquid (Point 1).

#### What happens when the temperature of a liquid increases?

As the temperature of a solid, liquid or gas increases, the particles move more rapidly. As the temperature falls, the particles slow down. If a liquid is cooled sufficiently, it forms a solid. If a liquid is heated sufficiently, it forms a gas.

#### How are temperature and pressure of gas related?

The temperature and pressure at which the gas gets liquified is said as critical temperature and critical pressure respectively. These are related to the boiling point of the gas to be liquified.
