Question

Meat can be classified as fresh (not frozen) even though it is stored at −1 °C. Why wouldn’t meat freeze at this temperature?

a) The temperature is not low enough for freezing
b) Presence of preservatives in the meat
c) The meat contains anti-freezing agents
d) Freezing point depression due to solutes in the meat

Answer 1

The freezing point depression due to solutes in the meat prevents it from freezing at -1 °C.

Step-by-step explanation:

The correct answer is d) Freezing point depression due to solutes in the meat.

Freezing point depression occurs when a solute is added to a solvent, causing the freezing point of the mixture to decrease.

In this case, the solutes in the meat act as antifreezing agents, lowering the freezing point of the meat below -1 °C. As a result, the meat does not freeze at this temperature.
