The specific heat capacity for water is 4.184 J/g°C. This means that 4.184J of heat is required to raise 1g of H₂O by 1⁰C. In this problem, you have 150g of water and want to increase the heat by 20°C. 

The equation you will want to use for this problem is:
 Cs = (q÷(m×Δt))

Cs = specific heat capacity
q = heat
m = mass
Δt = change in temperature


Plug your variables into the equation:

4.184 = (q÷(150×20))

Next, solve for q. This will be your answer.



Hope this helps you. 

Heat required=12,552 J

The specific heat capacity of a substance is the heat capacity of a sample of the substance divided by the mass of the sample.

Specific heat is given by:

Q = m*C*ΔT..........(i)

where,

C = specific heat capacity

Q = heat

m = mass

ΔT = change in temperature

The specific heat capacity for water is 4.184 J/g°C . This means that 4.184J of heat is required to raise 1g of H₂O by 1⁰C.

Given:

150g of water and want to increase the heat by 20°C.

On substituting the values in equation (i)

Q = m*C*ΔT

[tex]4.184 = \frac{Q}{150*20} \\\\ Q= 12,552 \text{J}[/tex]

Thus, heat required to change the temperature is 12,552 Joules.
