Question 13
F

A metal block is heated with an electric immersion heater to determine the specific heat capacity of the metal. The block is wrapped in insulation. Which explains why the insulation improves the result?

[1]
A

less energy is transferred to the block, so the block reaches a higher temperature

B

more energy is transferred to the block, so the temperature rise happens sooner

C

less energy is transferred from the heater, so a smaller temperature rise is needed

D

less energy is transferred to the surroundings, so more energy goes into the block
