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.
