It is a true statement that frozen water melts. As ice or frozen water rises in temperature, it will slowly change into a liquid state. It would be false to say otherwise.

Is it true or false that when solid melts it turns into gas?
both. It depends what substance it is. For example: solid water (ice) melts into liquid water (water) and then that melts into gas water (water vapour). Another example is that frozen carbon dioxide (c02)which is a solid also known as dry ice, melts into c02 gas hence the name dry ice because when it melts it goes straight into a gas state.
True or false When frozen water melts it is undergoing a physical change?
Actually it is undergoing a crappy change.
True or false dry ice is icefrom which all water has been removed?
False - dry ice does not contain water; it is frozen carbon dioxide

It is false that an ice cube melts when it's mechanical energy increases.
Does a wet rock generally melts at a lower temperature than a dry rock true or false?
True, a wet rock melts at a lower temperature!
Film can easily be frozen in time and space for analysis true or false?
False
A wet rock generally melts at a lower temperature than a dry rock true or false?
True.
Water works to expand joints in rocks because it expands as it evaporates true or false?
No. Water expands when it freezes, causing the rocks to crack and break.
When water freezes it contracts true or false?
It is false. Water expands on freezing.
Water is recycled in nature over and over?
true
Is this true of false that the temperature of a cup of tea is about -3 degrees C?
False: since tea is mostly water, if its temperature was -3 degrees C is would be frozen solid and you could not drink it.
