Question

How much heat must be removed from 750 grams of water at 0°C to form ice at 0°C?

Answer 1

250500 J

Explanation:

Given:

Mass (m) = 750 grams

We can determine the amount of heat removed by taking into account the following image:

This means that to go from water to ice there is an absorbed radiation dose of 334 J/g, therefore, the heat removed is:

`\begin{gathered} Q=m\cdot a \\ \\ \text{ We replacing:} \\ \\ Q=750\cdot334 \\ \\ Q=250500\text{ J} \end{gathered}`

The heat removed is 250500 joules.
