# When a gas is changed to a liquid phase, the gas?

## What is the phase change called when a gas turns into a liquid?

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.

## When liquid changes to a gas phase What is the liquid releasing energy?

Conversely, any transition from a less ordered to a more ordered state (liquid to solid, gas to liquid, or gas to solid) releases energy; it is exothermic. The energy change associated with each common phase change is shown in Figure 11.4.

## Does a liquid release energy or absorb energy when it changes into a gas?

Energy will be released to change from liquid to solid (fusion), gas to liquid (condensation), or gas to solid. Latent heat of evaporation is the energy used to change liquid to vapor. IMPORTANT: The temperature does not change during this process, so heat added goes directly into changing the state of the substance.

## What needs to happen before a gas can become a liquid?

You need to lose some energy from your very excited gas atoms. The easy answer is to lower the surrounding temperature. When the temperature drops, energy will be transferred out of your gas atoms into the colder environment. When you reach the temperature of the condensation point, you become a liquid.

## What are two ways that a liquid can be turned into a gas quizlet?

What are the pressure and the temperature of the normal boiling point of water? What are two ways that a liquid can be turned into a gas? Increase the temperature or decrease the pressure.

## At what temperature will both liquid and gas be present in benzene?

Benzene melts at 6°C and boils at 80°C; it is a liquid at room temperature. If both the normal melting point and the normal boiling point are above room temperature, the substance is a solid.

Density at 20°C Density at 100°C
gas: oxygen 1.33 g/L 1.05 g/L

## Which of these phase changes does not involve changing a liquid into a gas?

Which of these phase changes does NOT involve changing a liquid into a gas? In sublimation process a solid substance is converted into a gaseous substance. So, sublimation is the required answer as it does not involve changing of a liquid into a gas.

## Why does temperature remain constant when water boils?

When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. These rise to the surface and enter the atmosphere. In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling.

## When water boils does it release or absorb energy?

For example, when a pot of water is kept boiling, the temperature remains at 100 °C (212 °F) until the last drop evaporates, because all the heat being added to the liquid is absorbed as latent heat of vaporization and carried away by the escaping vapour molecules.

## What happens when vapor condenses into a liquid?

Condensation is the process by which water vapor in the air is changed into liquid water. As condensation occurs and liquid water forms from the vapor, the water molecules become more organized and heat is released into the atmosphere as a result.

## When you step out after a hot shower you feel cold but you can feel warm again if you step back into the shower area which process is responsible for this?

When you step out after a hot shower you feel cold, but you can feel warm again if you step back into the shower area. Which process is responsible for this? Condensation. When you step back into the shower area, the steam that is present condenses on your body, causing it to warm up.

## What liquid turns to gas?

Examples of Liquid to Gas (Vaporization)

Water to steam – Water is vaporized when it is boiled on the stove to cook some pasta, and much of it forms into a thick steam.

## What increases when a liquid becomes a gas at its boiling point?

Boiling. As a liquid is heated, its vapor pressure increases until the vapor pressure equals the pressure of the gas above it. Bubbles of vaporized liquid (i.e., gas) form within the bulk liquid and then rise to the surface where they burst and release the gas.

## Can gas turn into solid without being liquid?

Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.
