What happens to molecules when they are heated?

Back

When molecules are heated, they gain energy and move faster, leading to an increase in temperature.

What is equilibrium in terms of thermal energy?

Back

Equilibrium occurs when two objects at different temperatures come into contact and transfer energy until they reach the same temperature.

What is the significance of the 65-degree and 35-degree samples?

Back

When a 65-degree sample contacts a 35-degree sample, energy will flow from the hotter sample to the cooler one until they reach thermal equilibrium.
