Is melting of butter physical change or chemical?
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)
What change of state takes place when something sublimesfrom?
It is the phase change from a liquid to a gas.
When sugar is heated for a short time a thick colorless liquid substance is formed What kind of change takes place?
The change that takes place when sugar is heated to form a thick, colorless liquid substance is a physical change. This is because the molecular structure of the sugar remains the same even though its physical state has changed from solid to liquid.
What phase change from liquid to gas will take place if you add energy equal to the heat of vaporization?
The liquid will boil.
What is the term for the lumps when acid is added to milk?
When rennet (a complex of enzyme) is added to whole milk, a separation takes place into solid curds, and liquid whey.
What change is taking place when water evaporates?
This a phase change, from liquid to gas.
Is a liquid at normal temperatures and pressures a physical or chemical change?
A liquid at normal temperatures and pressures is a physical change. When a substance changes from a solid to a liquid or from a gas to a liquid without any chemical reactions taking place, it is considered a physical change.
When liquid water evaporates which has taken place molecular change or chemical change?
Physical change.
Is melting of butter physical change or chemical?
Physical, because the stuff that the butter is made out of doesn't change, just the state, or physical form, that it is in. (solid to liquid.)
When a substance changes from a solid to a liquid occurs?
This change in the state of matter (liquid to solid) is called freezing; it is a physical change, the chemical nature of the molecules is not changed.
What change of state takes place when something sublimesfrom?
It is the phase change from a liquid to a gas.
What changes takes place when ice turns into liquid?
A phase change.

What change of state takes place when something evaporates?
It is changing he element that is a liquid from a liquid to water vapor. A gas.
What changes takes place when ice turns into liquid water?
A phase change.
Why does a liquid cool when evaporated?
Evaporation Takes Place Layer By Layer. Then Heat, In The Stages Of Evaporation Just Effects The First Layer Of The Liquid . Heat Makes An Increase Of Enegry Between The Particles. The Particles, With That Energy, Trys To Move And Seperate ThemSelves From The Whole Liquid. The Higher Engery Partides Rise, Leaving The Less Engery Ones Behind, There For Making The Liquid Cool.
