Question

svens team put its insulated ice cube into a sealed plastic container. which type of thermal energy transfer was the team trying to prevent?

a. translation

b. radiation

c. conduction

d. convection

Explanation:

1. Analyze Option A: Translation is not a type of thermal energy transfer, so A is incorrect.
2. Analyze Option B: Radiation is transfer via electromagnetic waves. The sealed plastic and insulation are more for preventing contact - based transfer, not radiation mainly, so B is not the main one here.
3. Analyze Option C: Conduction is heat transfer through direct contact. The sealed plastic container (a poor conductor) and insulation around the ice cube are used to prevent heat from transferring to the ice through direct contact with the container or other objects, so this is the type they are trying to prevent.
4. Analyze Option D: Convection is heat transfer through fluid (liquid or gas) movement. Since the container is sealed, there is no fluid movement inside to transfer heat, so preventing convection is not the main goal here.

Answer:

C. Conduction
