Question

How much heat must be added to 150 grams of ice at 0°C to form water at 0°C?

Answer 1

Given:

The mass of the ice is m = 150 g

Required: The heat required to convert ice to water at zero degrees Celsius.

Step-by-step explanation:

The heat can be calculated by the formula

`Q=mL_f`

Here, the latent heat of fusion is

`L_f=\text{ 80 cal/g}`

On substituting the values, the heat will be

`\begin{gathered} Q=150\text{ g}*(80cal)/(g) \\ =12000\text{ cal} \end{gathered}`

Final Answer: The heat required to convert ice to water at zero degrees Celsius is 12000 calories.
