Condensation: change from a gas to a liquid -- water vapor in the air forms tiny drops of liquid water or ice (clouds). This is followed by precipitation: water that has gathered in the clouds and falls to the earth as rain, hail, sleet and snow. Some becomes ground water: water that has soaked into the earth, often between saturated soil and rock.
Evaporation: change in state from a liquid to a gas (liquid water becoming water vapor) Some of the water that forms clouds, then falls to Earth, is eventually evaporated again from the land and ocean.
water undergoes from solid state to liquid state at 0oC and from liquid state to gaseous [e.g. vapor, steam] state at boiling temp. 100oC provided the pressure is atmospheric: 1 ATM
- From liquid to solid
- From liquid to gas
The 6 phase changes are Freezing, Melting, Condensation, Sublimation, Evaporation and deposition.
okay this might help u understand better when water boils it becomes steam and rember this liquid to gas liquid to soild
The phase change is from a liquid to a gas.
Condenstaion, Evaporation
The phase change of water (liquid) to ice (solid) is called solidification.
The water vapour rises and comes out and if it is heated for a longer period the water comes out of the pot.
As the suns rays heat the water the particles in the water start to speed up. As this happens the water converts to water vapour and this process of converting water into vapours is called evaporation.Vaporization of an element or compound is a phase transition from the liquid phase to gas phase. There are two sorts of vaporization: evaporation and boiling.Evaporation is a phase transition from the liquid phase to gas phase that occurs at temperatures below the boiling temperature at a given pressure.Boiling is a phase transition from the liquid phase to gas phase that occurs at or above the temperature the boiling temperature.
A phase change is not a chemical change since the chemical remains the same; water is still water, whether it is in the solid, liquid, or gas phase.
Frost is a phase change of a gas to a solid (deposition). Water vapor turns directly to ice.
When ice melts and becomes water, that is a phase change. Same when water boils and becomes steam (a gas) that is also a phase change.
Vaporization is a change of phase.
Vaporization is a change of phase.
Water boiling is a phase change, which is a kind of physical change.
A phase change.
A phase change occur, energy is absorbed, water volume decrease.
It is best described as a phase change from liquid to vapor.
Boiling is a physical phenomenon, a change of phase.
When water boils, the bubbles are made of water vapor. Water is changing from the liquid phase to the gas phase, but it doesn't change all at once, so you get bubbles of gas inside the liquid. The phase change will happen first at the location where heating is taking place, so if you have a pot on a stove, the bubbles will form at the bottom of the pot, and then rise to the top.
a physical change called melting. It is also called a phase change.
A good example of a simple Physical Change occurs in a tea pot. The hot, liquid water boils and goes off as steam. Steam is still water (no chemical change,) but is now a gas.
A physical change.
