Lesson 3

Having a Meltdown

Density of Liquids and Solids

The formula to determine the density of an object is D= m/v. That's Density equals Mass divided by Volume. It can also be switched around to find mass as long as you know the density and volume and can help find volume as long as you know density and mass.

 

These three things all have a proportional relationship.

The volume of water in 1 liter of rain is more than in 1 liter of snow because snow is less dense therefore can't fit as much actual water in the same amount of volume as rain.

This carries into every phase. Every time something changes phases i.e. liquid to gas or solid or vice versa, there is a change in density.

Practice Problems

3. Snow is not as dense as ice and so ice contains a greater volume of water.

4. Liquid water will take up more volume than ice because it is not as dense as ice.
