A. Each beaker of liquid has the same amount of heat energy for same temperature
difference (ie, thermal capacity).
B. Each beaker of liquid receives the same heat energy.
C. Liquid 1 receives more heat energy than liquid 2.
D. The thermal capacity of liquid 1 is less than the thermal capacity of liquid 2.

Answer :
D. The thermal capacity of liquid 1 is less than the thermal capacity of
liquid 2.
Explanation :
- The quantity of heat necessary to change the temperature of an object by a specific degree is known as thermal capacity, also known as heat capacity. A substance's water equivalent is the amount of water required to absorb the same amount of heat as that substance does for one degree of temperature increase.
- Because liquid 2 has a higher specific heat capacity than liquid 1, it is preferred. As a result, given the same quantity of heat energy absorbed, the temperature of liquid 1 rises less than that of liquid 2. As a result, liquid 2 would be a better heat reservoir for preventing the freezing of juice bottles.
