Final answer:
The characteristics that determine how easily two substances change temperature are specific heat, volume, and area in contact.
Step-by-step explanation:
The characteristics that determine how easily two substances change temperature include:
- Specific heat: It is the amount of heat energy needed to raise the temperature of a substance by a certain amount. Substances with a higher specific heat require more heat energy to change temperature.
- Volume: The volume of the substances in contact affects how easily they change temperature. A larger volume allows for more heat transfer, leading to a more significant change in temperature.
- Area in contact: The larger the area in contact between two substances, the more heat can be transferred, resulting in a greater change in temperature.
