Question
The diagram below shows two substances, A and B, which are at different temperatures.
What will happen when substance A is dropped into substance B?
a
Substance A and B will exchange heat, and they both will reach 50°C.
b
Substance A and B will exchange heat, and they both will reach 25°C.
c
Substance A will get even warmer as heat flows into it from substance B.
d
Substance A and B will eventually reach the same temperature.

The correct answer is:
**d** Substance A and B will eventually reach the same temperature.
When two substances at different temperatures come into contact, they will exchange heat until thermal equilibrium is reached, meaning they will eventually be at the same temperature. The final temperature will depend on the specific heat capacities and masses of the substances, but they will not remain at their initial temperatures.
