Generally a solid become a liquid by melting or a gas by sublimation; but not all the solids can be melted.
You can observe the formation of a precipitate (solid) from two clear solutions or a color change in the reaction mixture. Another indication is the release or absorption of heat or light during the reaction.
The following are ways to change the size and shape of a solid material without forming a new substance, except one. Which one is it?
Solids change their shapes in many ways. Solids will melt if they are in hot temperatures, and this changes their shape.
If you add heat to matter, it can either get it hotter, or it can change the state of matter (for example, from solid to liquid).
evaporation is a way
The microwave oven can change water's solid form (ice) to liquid. It can also change water's liquid form into that of a gas (steam).
In what ways do humans affect the natural. Students observe the changes people make in the natural physical characteristics of a place over time.

There are numerous ways to observe and photograph tigers while on vacation.
smell , hear , see, taste , eat
there are lots of types of resin, but in composite material basically, they use three types epoxy, vinylester and polyester. other ways to define thermosetting after heating do not change state like from liquid to solid. after that there is no change from solid and thermoplastic after heating change like from solid to liquid, it can change from liquid to gas. Excellent answer if your studying for a PHD, however lets just go with a few resins for the novice: 1. Amber 2. Mastic 3. Rosin 4. Bitumen 5. Magilp 6. Japan 7. Copal.
