A change of phase, from solid to liquid, or liquid to gas, or gas to liquid, etc., is also sometimes called a change of state.
The freezing of water is an example of phase change.
Changing a substance from solid into a liquid is called a change of state or a change of phase. Melting is the name given to the change of state from a solid to a liquid.
melting point
a liquid solid in a solid is example of an important collodial system called solid emulsion or gel. butter is one where liquid is water and solid is fat, oher eg: flesh
Changing from a solid to a liquid is a physical change as is changing from a liquid to a gas.
Example of solid changing toliquid:when you take an ice and put it to thaw out it changes to water (liquid) and is the same for liquid to solid; you freeze water(liquid) and it turns to ice (solid)
When something is changing from a solid to a liquid, it is melting.
When something is changing from a solid to a liquid, it is melting.
Gas -> liquid = condinsation Liquid -> solid = solidification Solid -> liquid = fusion Liquid -> gas = evaporation Solid directly to gas (with out becoming liquid) = sublimation Example = dry ice at room temperature.
Yes it is a physical change not a chemical change. p.s. an example of a chemical change is an apple roting
We know that there are four states of matter. Solid, liquid, gaseous and ionic (plasma) As one substance changes from one state into the other it is known as change of state Example: Ice (solid) melts into water (liquid) and gets evaporated ( gaseous) as water vapour.
Changing solid to liquid by the application of heat is an endothermic process. Liquidation.
