Question

How many calories of heat are required to change 1 gram of ice at 0°C to liquid water at 0°C?

Answer 1

Given:

The amount of ice is,

`m=1\text{ g}`

To find:

The amount of heat is required to change 1 gram of ice at 0°C to liquid water at 0°C

Step-by-step explanation:

The latent heat for melting of ice is,

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

The amount of heat for the ice to melt is and become water at

`0\text{ }\degree C`

is,

`\begin{gathered} H=mL \\ =1*80 \\ =80\text{ cal} \end{gathered}`

Hence, the amount of heat is 80 cal.
