AnswersDriveWhen this happens, all of the molecules go flying apart and become a gas (like when you boil water to make steam). The process of gas molecules leaving the liquid to go into the gas is called "evaporation." The opposite process is called "condensation."
What is it called when a substance changes from a liquid to a gas?
For example, a solid may become a liquid. This phase change is called melting. When a solid changes into a gas, it is called sublimation. When a gas changes into to liquid, it is called condensation. That allows the solid substance to have a definite volume and shape.
What is the change of state from a liquid to a gas?
The change of state from a liquid to a solid is called freezing. B. Removing Energy: Removing energy will cause the particles in a liquid to begin locking into place. A. Boiling and Evaporation: Evaporation is the change of a substance from a liquid to a gas.
1
Is Steam a gas?
Steam is water in the gas phase, which is formed when water boils. Steam is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as this water vapour condenses.
2
Why does the temperature of ice not change when it melts?
The example we will use here is ice melting into water. The heat is used to break the bonds between the ice molecules as they turn into a liquid phase. Since the average kinetic energy of the molecules does not change at the moment of melting, the temperature of the molecules does not change.
3
What is the process that occurs when water vapor is cooled and changed from a gas to a liquid?
The process in which water vapour changes into a water droplet or ice crystal is called *condensation. This happens because water vapor in the air gets cold and changes back into liquid, forming clouds. In transpiration, water from these objects evaporates into the atmosphere.
4
What is the magic temperature for every substance?
There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid. For water, the temperature needs to be a little over zero degrees Celsius (0oC) for you to melt.
5
How does a gas become a solid?
Under certain circumstances, gas can transform directly into a solid. This process is called deposition. Water vapor to ice - Water vapor transforms directly into ice without becoming a liquid, a process that often occurs on windows during the winter months.
6
What causes a change of state?
Adding energy to matter causes a physical change — matter moves from one state to another. For example, adding thermal energy — heat — to liquid water causes it to become steam or vapor — a gas. Taking away energy also causes physical change, such as when liquid water becomes ice — a solid — when heat is removed.

What is the meaning of phase change?
1. phase change - a change from one state (solid or liquid or gas) to another without a change in chemical composition. phase transition, physical change, state change. freeze, freezing - the withdrawal of heat to change something from a liquid to a solid. liquefaction - the conversion of a solid or a gas into a liquid.

What happens to the particles in a solid when it melts?
When a solid is heated the particles gain energy and start to vibrate faster and faster. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.

What is the name of the phase change from liquid to gas?
Phase Changes
| Phase Change | Name | Intermolecular Forces Increase or Decrease? |
|---|---|---|
| solid liquid | melting or fusion | increase decrease |
| liquid gas | vaporization or evaporation | increase decrease |
| gas solid | deposition | increase decrease |
| gas liquid | condensation | increase decrease |

What is it called when a gas turns into a solid?
Deposition is a thermodynamic process, a phase transition in which gas transforms into solid without passing through the liquid phase. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation. This causes the water vapor to change directly into a solid.
11
What is it called when a liquid turns into a solid?
These are called the states of matter. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING. If water is heated, it changes to steam (a gas).
12
What is gas to liquids?
Gas-to-liquids (GTL) is a process that converts natural gas to liquid fuels such as gasoline, jet fuel, and diesel. GTL can also make waxes. The most common technique used at GTL facilities is Fischer-Tropsch (F-T) synthesis.
13
What are the different phase changes?
Video: Phase Change: Evaporation, Condensation, Freezing, Melting, Sublimation & Deposition. Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition.
14
How do you turn a solid to a gas?
The opposite happens when you cool down a gas: first it becomes a liquid, then a solid. Some solids can even become a gas without first becoming a liquid; this is called "sublimation". For instance, ice in a freezer slowly disappears, since it's subliming into a gas.
15
Are a lot like gases but the atoms are different because they are made up?
Plasmas are a lot like gases, but the atoms are different, because they are made up of free electrons and ions of an element such as neon (Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth.
16
What provides the energy for the water cycle?
The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form cloudsclouds that move over the globe and drop rain and snow. This process is a large part of the water cycle.
17
What is the relative humidity when the air temperature is at its dew point?
A relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the moisture content remains constant and temperature increases, relative humidity decreases, but the dew point remains constant.
18
What is water in the form of gas?
Clouds, snow, and rain are all made of up of some form of water. A cloud is comprised of tiny water droplets and/or ice crystals, a snowflake is an aggregate of many ice crystals, and rain is just liquid water. Water existing as a gas is called water vapor.
19
What is it called when a gas changes to a liquid?
Let's focus on phase changes that involve materials changing from one state of matter to another. This kind of phase change--liquid to gas--is called evaporation or vaporization. Water vapor can in turn be cooled to form liquid water. This kind of phase change--from gas to liquid--is referred to as condensation.

What are the different states of matter?
In physics, a state of matter is one of the distinct forms in which matter can exist. Four states of matter are observable in everyday life: solid, liquid, gas, and plasma.
