Matter that has a definite shape and a definite volume is

• a liquid. 
• an element. 
• a solid.
• a gas.

We know that air is a mixture and not a compound because

•  it can be heated to a higher temperature.
• it can be compressed to a smaller volume.
• it is colorless.
• its composition can vary.

Matter can be defined as anything that

• has weight.
• has mass and volume.
• is uniform throughout.
• exhibits both chemical and physical properties.

Which of the following is best classified as a homogeneous mixture?

• pizza 
•  blood
