Given:
by putting the value into the above formula so, the value is 2.7 J
Answer:
8740 joules are required to convert 20 grams of ice to liquid water.
Explanation:
The amount of heat required (), measured in joules, to convert ice at -50.0 ºC to liquid water at 0.0 ºC is the sum of sensible heat associated with ice and latent heat of fussion. That is:
(1)
Where:
- Mass, measured in grams.
- Specific heat of ice, measured in joules per gram-degree Celsius.
,
- Temperature, measured in degrees Celsius.
- Latent heat of fussion, measured in joules per gram.
If we know that ,
,
,
and
, then the amount of heat is:
8740 joules are required to convert 20 grams of ice to liquid water.
