Question

Why is the temperature of the liquid in the flask on the previous page measured when the liquid in the thermometer has stopped rising? Explain
How can the thermometer in the flask on the previous page be used to demonstrate the relationship between heat transfer and kinetic energy? Explain.

Answer 1

when heated, the molecules of the liquid in the thermometer move faster, causing them to get a little further apart. this results in movement up the thermometer. when cooled, the molecules of the liquid in the thermometer move slower, causing them to get a little closer together.
