Question

What is the specific heat capacity of a material if 2000 J of heat energy can raise the temperature of 10 g of it by 140°C?

Answer 1

Specific heat capacity, = 1.43 J/g°C

Step-by-step explanation:

Given the following data;

Mass = 10 g

Change in temperature = 140°C

Quantity of heat = 2000 J

To find the specific heat capacity;

Heat capacity is given by the formula;

`Q = mcdt`

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.
• dt represents the change in temperature.

Making c the subject of formula, we have;

`c = \frac {Q}{mdt}`

Substituting into the equation, we have;

`c = \frac {2000}{10*140}`

`c = \frac {2000}{1400}`

Specific heat capacity, = 1.43 J/g°C
