Jeff is out in the woods, trying to heat 0.5 kg of water to make sure it is safe to drink. He knows from his survival handbook that he needs to add
157.125 kJ of heat to the water in order to make it safe. What is the change in temperature that the water will experience after that heat is added?
(Note: Water has a specific heat of 4,190 J/kg°C.)

Answer 1

The temperature change is 75 degrees.

What is specific heat capacity?

The specific heat capacity of a substance is the amount of heat added to a substance in order to make the temperature of 1 Kg of the substance to rise by 1 degree.

We know that;

H = mcdT

Where;

H = heat added

m = mass of water

c = heat capacity of water

dT = temperature change

So;

157.125 × 10^3 = 0.5 × 4,190 × dT

dT = 157.125 × 10^3/0.5 × 4,190

dT = 75 degrees
