Changes in Matter Practice Test

Sue places a beaker of 20°C water on a burner and heats the

water until it reaches 100°C. She measures the temperature and

the mass of the beaker of water every minute for 12 minutes. The water temperature increases.

What will happen to the mass of the beaker?

• The mass will increase.

• The mass will decrease then increase.

• The mass will decrease.

• The mass will stay the same.

Jess has two bricks of clay that are the same mass. He takes one brick of clay and

slices it into separate pieces. He takes the pieces from the sliced brick and rolls

each piece into a coil. He then uses the coils to make a clay pot.

Jill weighed the nails before her mom left them outside. Then she weighed the

nails after they were left outside for two weeks.

Which sentences describes what Jill noticed about the mass of the nails

before and after they were left outside.

• The mass of the nails decreased because

  rust

  dissolved the nail.

• The mass of the nails increased because

  matter was added to the nails during a chemical change .

• The mass of the nails remained the same because

  rust is heavy.
