Two identical beakers contain equal masses of water at the same initial temperature. Each receives the same electrical energy. Beaker P is insulated and beaker Q is not. Each student uses the electrical energy to calculate specific heat capacity. Which comparison is expected?

[1]
A

P has a larger temperature rise and a smaller calculated value.

B

P has a larger temperature rise and a larger calculated value.

C

P has a smaller temperature rise and a larger calculated value.

D

P has a smaller temperature rise and a smaller calculated value.
