6.P.2 Review

Everything that has mass and takes up space

• mass

• matter

• volume

The amount of space, matter or a three dimensional, object takes up

• element

• mass

• volume

One of the three basic forms of matter that has a definite volume, but it takes the shape of its container.

• solid

• liquid

• gas

What change occurs when a liquid evaporates?

• The particles absorb heat and get closer together.

• The particles absorb heat and spread farther apart.

• The particles release heat and get closer together.

• The particles release heat and spread farther apart.

Sam found two pieces of pure silver on two different continents and melted them. Why did the two pieces of pure silver have the same melting point?

• Silver is a metal with high conductivity.

• The melting point of all metals is the same.

• Silver is composed of the same types of atoms.

• The melting point of all natural minerals is the same.

What is the best way to determine if a sample is pure gold?

• compare the color of the sample with a sample of pure gold

• compare the luster of the sample with a sample of pure gold

• compare the volume of the sample with a sample of pure gold

• compare the melting point of the sample with a sample of pure gold

How does a 5-g sample of pure gold compare to a 50-g sample of pure gold?

• They have the same melting point but different masses.

• They have the same volume but different melting points.

• They have the same volume but different boiling points.

• They have the same mass but different boiling points.

What happens to the movement of water particles when the water is cold compared to when it is hot.

• The particles in the cold water move more slowly.

• The particles in the cold water move more quickly.

• The particles in the cold water move more freely.

• The particles in the cold water do not move at all.

Graphite, diamond, and glassy carbon are all forms of the element carbon. Why are all three considered carbon?

• They were originally fossils.

• They are mined from the same region.

• They are composed of the same kind of atoms.

• They were formed from carbon-containing organisms.

Which best represents atoms moving closer together during a phase change?

• water in a lake gaining heat energy and evaporating

• ice on a mountaintop gaining heat energy and melting

• ice in the atmosphere losing heat energy and precipitating

• water vapor high in the atmosphere losing heat energy and freezing
