States of Matter Practice Problems
Grades 4-7 · 5 problems
Practice identifying and understanding the different states of matter. This tool will help you master the concepts of solids, liquids, and gases.
Tip: Remember that matter can change from one state to another by adding or removing energy (usually in the form of heat).
1
What state of matter has a definite volume and a definite shape?
2
Water freezing into ice is an example of what change of state?
3
What state of matter takes the shape of its container and has a definite volume?
4
What is the process called when a solid changes directly into a gas, skipping the liquid phase?
5
If a sealed container of gas is heated, what happens to the pressure of the gas inside the container?
Common Mistakes
- Confusing evaporation and boiling
- Thinking that gases have a definite volume
- Forgetting that mass is conserved during phase changes
