This is how to find the volume of an object that does NOT have a regular shape.
By placing the object in water in a graduated cylinder and measuring the water level difference

What happens to the spaces between the atoms when you add heat into a substance (when heat gets ABSORBED by the substance?)
The spaces between the atoms get larger
500
We know light is an example of (matter, non-matter), BECAUSE ____________.
We know light is an example of non-matter, BECAUSE it does not have mass or volume.
500
What is the reason the number “3” is written at the end of cm3 when finding the volume.
Because cm is multiplied 3 times for length, width, and height?

If I have a piece of gold with a density of 1.5 g/cm3, and I cut the gold in half, will the density change?
NO THE DENSITY WILL NOT CHANGE
500
Why do people run more quickly through air than through a pool?
Because the molecules in the pool are closer together and more difficult to move through
500
Where do the water droplets on the outside of a glass come from?
The water droplets are formed from water in the gas phase hitting the cold glass and condensing into water droplets
