True.
Every chemical or physical change in matter includes a change in energy.
Actually it is undergoing a crappy change.
When a cake is baked it changes its physical appearance and is thus said to undergo a physical change.However there are many concurrent chemical changes:sugars caramelizeproteins coagulateleavening agents (baking soda etc.) release carbon dioxidestarches, oils and fats oxidize
Since boiling results in change in the physical properties of a substance (no change occurs in the chemical composition), boiling can be termed as a physical phennomenon (property). Whereas boiling point is a part of this property i.e a temperature at which the substance changes into vapors.

Chemistry is considered to be a physical science.

True. A physical change is a change from one state to another without a change in chemical chemistry.
Yes, it is possible.
It is false. When a physical change takes place, the colors, texture, brittleness will change.
No. It is still water. So that makes it a physical change.
False. Changing the size and shape of pieces of wood is a physical change because the wood's composition does not change.
Every chemical or physical change in matter includes a change in energy.
I'd say no. Melting just changes the physical properties. Example: A rubber ball. If you melt a rubber ball it will still be rubber, just in a different form.

false - it's a physical change. The sugar remains sugar only in solution.
