The table lists some physical properties of two objects. Based on their properties, which of the objects is most likely a metal?

• Object 1, because it is a solid that is less dense than water

• Object 2, because all metals float in water

• Object 2, because metals conduct thermal energy and electricity

• Object 1, because it can be used to provide insulation for thermal energy

What is the least dense liquid in this container?

• Honey

• vegetable oil

• lamp oil

• water

What is the formula for calculating density?

• Mass ∗ Volume
• Volume ∗ Mass
• Mass ÷ Volume
• Volume ÷ Mass

The particles in a liquid are...

• loose and have high energy

• tightly packed and have very little energy

• move freely and have lots of energy

• the particles don't move
