In the water displacement method for finding volume

•  You subtract the final volume from the initial volume
• You subtract the initial volume from the final volume
• You add the initial and final volumes
• You divide the final volume by 2 

Density is a characteristic property of a substance. This means that the density of water 

• Changes depending on the volume 
• Stays the same regardless of the volume
• Is greater for a greater mass of water
• Is less for a smaller mass of water 

An object should float in a liquid if it is 

• Denser than the liquid 
• Less dense than the liquid
• Lighter than metal
•  Shaped like a ball 

Which of the following is a sign that a chemical reaction has occurred?

• change in shape
• melting
• formation of a gas
• dissolving
