Item AM050003: If a liquid is stirred so that the speed of its molecules increases, the temperature of the liquid will increase.
A liquid is stirred so that the speed of its molecules increases. What happens to the temperature of the liquid?
- The temperature increases.
- The temperature decreases.
- The temperature stays the same.
- It is not possible to say anything about the temperature without more information.

- Notes
- See evidence statement for NGSS performance expectation MS-PS-1-4. An increase in kinetic energy of the particles can cause: An increase in the temperature of the system as the motion of the particles relative to each other increases.
