First, melting is the phase change of solid to liquid and evaporation is the phase change of liquid to gas. Second, Evaporation requires more energy than melting. Evaporation, heat of vapoization constant, is 2260 J/g. Melting, the heat of fusion constant, is 334 J/g.
What else can I help you with?
How are meting and evaporating different?
melting(not meting i supose)=solid to liquid evaporating=liquid to gas ;)
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.
Give 5 examples of a reversible change?
Melting wax Melting ice freazing water Evaporating the water Cooling the steam
Can matter change phases?
Yes. Matter can change phases in the process of melting, freezing, evaporating, and simulating.
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 wick necesarry in a burning candle?
Yes that is what burns the melting wax prolongs the burning time by slowly evaporating
What adjectives describes physical change?
A physical change is when something changes from one state of matter (solid, liquid, or gas) without changing chemical composition. When ice melts or water freezes or evaporates, it remains H2O, so these are physical changes.
What are examples of solid turning into a gas?
Ice melting and evaporating.
What is an example of oxidation water evaporating sugar melting paper burning or all of the above?
An example of oxidation would be paper burning because it involves a chemical reaction where paper combines with oxygen in the air to produce heat and light. Water evaporating and sugar melting are physical changes, not chemical reactions involving oxidation.
Do proteins have definite melting points?
Different proteins have different melting points.
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.
Is melting snow a physical change or chemical change?
Snow disappearing is a physical change. It is a combination of melting and then evaporating and of sublimation.
