if a certain material is able to SCRATCH another material, you can compare the HARDNESS of the material

• True
• False

Physical changes in matter are NOT usually reversible.

• True
• False

Answer explanation

Think to yourself - if a tray of ice melts, can you put the tray back in to let the water freeze again? YES!! it is reversible

Why is a WOODEN spoon better than a METAL spoon for stirring a boiling pot of soup

• Wood does not conduct heat, but metal does. The metal spoon could get very hot and burn you.

• Metal spoons do not conduct heat, and metal would not burn you.

• Wood spoons just feel nicer!

• Metal spoons are what all the top chefs use.

Explain why boiling water is an example of physical change.

• When water boils, it does not change chemically. It can be cooled down or warmed up again.

• The water warms up as it boils, but it can not change after that. It has physically and chemically changed.
