1. Substances don't have to be cold to freeze.
2. Phase is a relationship between particles.
3. Freezing temperature equals to the melting temperature.
Hope this helped.

What are the Changes of state?
There are three main states that a substance can exist as: solid, liquid and gas. The transition between these states occur when a substance is heated or cooled past their freezing/melting or boiling/condensing points. Solid -> Liquid = Melting Liquid -> Gas = Boiling Gas -> Liquid = Condensing Liquid -> Solid = Freezing
What are the three types of a physical change?
transition phases from solid to liquid to gas.
Explain why the boiling point and the melting point can be used to help identify substances-?
It's because substances have different boiling point and freezing point. By finding the exact boiling point and freezing point, you can identify a substance. Keep in mind that a material's melting point is the same as its freezing point. These are just different terms for the same thing, it just depends on whether energy is being removed from a substance (freezing) or if energy is being added to a substance (melting). The same thing also applies to the boiling/condensation point.
What is the melting point of gold silver and copper?
Melting point of Gold = 1064.18 °C Melting point of Silver = 961.78 °C Melting point of Copper = 1084.62 °C Of cause an alloy of all three would probably have a eutectic melting behavour
what are three things affected?
what are three things affected by friction
What does melting point and freezing point mean?
There are three states of matter: gas, liquid and solid. The melting point is where a solid turns to liquid. The freezing point is where a liquid turns to solid.
What are the three changes that causes heat in substances?
1. melting 2.boiling 3.freezing
Identify three physical properties of water and two physical changes it can undergo?
tension versibilty and buyanancy , freezing and melting
What three standard points define the common temperature scales?
Absolute zero, melting/freezing point of pure water, and boiling point of pure water.

What are three kinds of changes in matter?
If we take solid, liquid and gas being the three main states of matter (plasma being an arguable fourth), then from solid to liquid, the process melting occurs, from liquid to gas evaporation or boiling (they are different things) occur. Then from gas to liquid condensation occurs and from liquid to solid freezing occurs.
What is one characteristic property of a substance?
i will give you three....melting point, boiling point, freezing point and one more is density
What three things can happen to a sedimentary rock in the rock cycle?
erosion and weathering heat and pressure melting and solidification

Which of these is a chemical change copper melting or water freezing or iron rusting or gas condensing?
The only example of a chemical change in the list is iron rusting. The other three are all examples of physical changes.
