Question

How much heat is required to raise 100 grams of water (c= 4.18) by 5 degrees Celsius?

Answer 1

Heat capacity, Q = 2090 Joules.

Step-by-step explanation:

Given the following data;

Mass = 100 grams

Specific heat capacity = 4.18 J/g°C.

Temperature = 5°C

To find the quantity of heat required;

Heat capacity is given by the formula;

`Q = mct`

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

t represents the temperature of an object.

Substituting into the formula, we have;

`Q = 100*4.18*5`

Heat capacity, Q = 2090 Joules.
