Question

Shane performed the following trials in an experiment.

Trial 1: Heat 30.0 grams of water at 0 °C to a final temperature of 40.0 °C.
Trial 2: Heat 40.0 grams of water at 10.0 °C to a final temperature of 40.0 °C.

Which statement is true about the experiments?

The same amount of heat is absorbed in both the experiments because the product of mass, specific heat capacity, and change in temperature are equal for both.

The same amount of heat is absorbed in both the experiments because the heat absorbed depends only on the final temperature.

The heat absorbed in Trial 2 is about 3,674 J greater than the heat absorbed in Trial 1.

The heat absorbed in Trial 2 is about 5,021 J greater than the heat absorbed in Trial 1.

Answer 1

The heat transfer (Q) is given by mass, specific heat, and the change in the temperature. The heat absorbed in both trials is the same as Q is the same for both. Thus, option a is accurate.

What is heat transfer?

Heat transfer is the gain and loss of heat by the system. It is given as the product of the mass, specific heat, and the change in the temperature. Heat transfer is shown as,

$\rm Q = \rm m c \Delta T$

Q for trial 1 is calculated as:

Q = 30 * 4.18 * 40

   = 5016 J

Q for trial 2 is calculated as:

Q = 40 * 4.18 * 30

   = 5016 J

Therefore, the heat absorbed is the same for both as the heat transfer (Q) is the same in both trials.
