Question

Hello I’m having difficulty answering this question and could use some help!

Answer 1

Given:

The mass of water, m=15 g=0.015 kg

The initial temperature of the water, T₁=50 °C

The final temperature of the ater, T ₂=100 °C

To find:

The heat required.

Step-by-step explanation:

The specific heat of water is, c=4180 J/(kg K)

The heat required to raise the temperature of the water is given by,

`\begin{gathered} Q=mc\Delta T \\ =mc(T_2-T_1) \end{gathered}`

On substituting the known values,

`\begin{gathered} Q=0.015*4180*(100-50) \\ =3135\text{ J} \end{gathered}`

Final answer:

Thus the correct answer is option C.
