Which of the following forms a new substance melting freezing evaporating burning?
Burning chemically alters a substance, creating different / new substances as a result. Melting, freezing, and evaporating are all different phases of the same substance.
What do melting and evaporation have in common?
melting and evaporating are both a change in matter. also during evaporation and melting there is no change in temperature. melting and evaporating are both a change in matter. also during evaporation and melting there is no change in temperature.
Is a candle an example of sublimation?
No, a candle is not an example of sublimation. Sublimation is the process by which a substance transitions from a solid directly to a gas without passing through the liquid phase. Candles involve the solid wax melting into a liquid state and then being converted into gas through combustion.
Is melting gold a chemical change?
No, melting always is physical.As to the previous answer: reacting gold with an acid is not melting but oxidation.
Which of them is a reversible change coffee dissolving Water boinling Chocolate melting wood burning?
Coffee dissolving, water boiling and chocolate melting are reversible physical transformations whereas wood burning is a chemical combustive transformation.
Is a wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
Which of the following forms a new substance melting freezing evaporating burning?

What will result in a chemical change melting ice to obtain water evaporating alcohol into vapor drying wood in a shed burning coal in a furnace?
its D. burning coal in a furnace
Why is melting a physical property of the wax but flammability in a chemical property?
Melting doesn't change the composition of a compound (substance).Burning is a chemical reaction, an oxidation - new compounds are formed.
How are meting and evaporating different?
melting(not meting i supose)=solid to liquid evaporating=liquid to gas ;)
Give 5 examples of a reversible change?
Melting wax Melting ice freazing water Evaporating the water Cooling the steam
What is the evaporating point of matter?
The evaporating point of matter refers to the temperature at which a substance transitions from its liquid state to a gas. It is also known as the boiling point for liquids with a defined melting point.
What is the melting point of papyrus?
Not melting of papyrus but a rapid burning.
What is an example of a physical change tarnishing rusting burning or melting?
Melting is an example of a physical change because it does not change the chemical composition of the substance undergoing the change. Tarnishing, rusting, and burning are examples of chemical change because they are caused by chemical reactions, which change the chemical composition of the substances undergoing the change.
What name is given to a process such as a burning a candle?
melting and burning
What is an example of a physical change burning melting rusting tarnishing?
Melting! A physical change would be to change something from Solid <--> Liquid <--> Gas
Can matter change phases?
Yes. Matter can change phases in the process of melting, freezing, evaporating, and simulating.
