Question

Find the amount of heat energy needed to convert 150 grams of ice at -15°C to ice at -63°C.
Group of answer choices

A. (-) 14760 Joules because the ice is being heated.

B. (-) 14760 Joules because the ice is cooling.

C. 14760 Joules because the ice is cooling.

D. 14760 Joules because the ice is being heated.

Answer 1

The heat needed is (-) 14760 Joules because the ice is cooling.

What is heat?

The term heat refers to a form of energy that can be observed as a result of temperature difference between two bodies. We can recall that heat always flows from the hotter to the cooler body.

Given that the heat added to a substance can be calculated by the use of H = mcdT

Where;

H = heat

m = mass

c = specific heat capacity

T = temperature change

Hence;

H = 150 g * 2.03 Jg∘C * (-63 - (-15))

H =  (-) 14760 J

Hence the heat needed is (-) 14760 Joules because the ice is cooling.
