During an experiment I add heat energy to a liquid. Which state of matter does the liquid become?
A gas
What is a mixture?
A combination of 2 or more substances that are not chemically joined together
Name a property of a solid discussed in class.
Cannot flow, cannot be compressed, definite shape and volume
Ice, liquid water, and water vapor are the three WHAT of matter for water?

Name a property of a gas that we discussed in class.
Can flow, can be compressed, no definite shape or volume
Is changing the state of matter a physical or chemical change?

Losing
Name a property of a liquid discussed in class.
Can flow, cannot be compressed, a definite volume that takes the shape of the container
TRUE OR FALSE. My particles are freely moving around with lots of energy
TRUE
Why can we see the liquid and solid forms of water, but not the gas form?
Because the particles are spread far apart and moving freely
Also, light passes right through without bouncing off the solid or liquid shape
