Question

Beaker A with 100 mL of sand or Beaker B with 100 mL of vegetable oil. Both heated by 15°C.

a. Beaker A will heat up faster than Beaker B.
b. Beaker B will heat up faster than Beaker A.
c. Both Beaker A and Beaker B will heat up at the same rate.
d. The question doesn't provide enough information to determine.

Answer 1

Beaker B will heat up faster than Beaker A because the specific heat capacity of vegetable oil is lower than that of sand.

Step-by-step explanation:

The correct answer is b. Beaker B will heat up faster than Beaker A.

The specific heat capacity of vegetable oil is lower than that of sand. Specific heat capacity refers to the amount of heat energy required to raise the temperature of a substance. A lower specific heat capacity means that a substance will heat up faster.

An example that demonstrates this is when you cook with oil and water. The oil heats up faster than water because it has a lower specific heat capacity.
