What state of matter does the material have to be in if it can melted?

solid

What is the melting point of table salt?

What is a physical change?

What is a solution?

A "Well Mixed" mixture usually in liquid. (usually so mixed you cannot see the individual ingredients

EX: Salt water

What is an element?

Pure substances that cannot be broken down into any other substance by physical or chemical means

(if you smash it, burn it, freeze it, or pulverize it..... it is still the same substance)
