What happens to a liquid if you add heat? What is this change in matter called?
The water will heat up to gas and the water will evaporate.
What happens to the gas if you add heat? What is this change in state called?
The gas will turn into a liquid and condensation will happen
What are the 3 ways to measure matter?
mass, weight, volume
How can you prove that air has mass? (Think of the air lab stations we did)
When it snows outside in the wintertime, how come the snow stays a solid and does not melt into a liquid?
The cold temperature is below frozen, keeping the snow in its solid form. (32 degrees to freeze)
What temperature does it need to be for a liquid to turn into a solid?
32 degrees
How do gases help hot air balloons rise?
