Thermal Energy

3. the process of testing a design and then making changes to the design based on testing
4. a variable or condition you control and keep the same for the entire investigation
6. what it takes to make an object move
8. the range of conditions over which a model or experimental setup provides useful data or explanations
11. variable or condition that is purposely changed in the investigation
12. occurring without a plan or pattern
14. cooling that is caused by a liquid evaporating to a gas and leaving the system
15. a state of balance between two objects with the same temperature
16. when objects collide, energy can be passed from one object to another
17. the transfer of thermal energy

1. a measure of how hot or cold an object is
2. the measured results of the investigation
5. the total kinetic energy of an object’s molecules
7. the energy carried by moving objects
9. the systematic process of gathering data to measure how well a solution meets the criteria
10. occurring without an obvious outside cause
13. making the best or most effective version
