Answer:
The total amount of heat is 250.64 kcal.
Explanation:
Given that,
Total amount of heat = 2.000 kg
Temperature of snow = -15.00°C
Temperature of water = 38.00°C
Heat of fusion of water = 1.44 kcal/mol
Specific heat of solid water = 0.488 cal/g°C
Specific heat of liquid = 1.00 cal/g°C
We need to calculate the heat required to bring temperature -15°C to 0°C snow
Using formula of heat
Put the value into the formula
We need to calculate the heat required to convert 0°C snow into 0°C water
Using formula of heat
Put the value into the formula
We need to calculate heat required to increases temperature of water from 0°C to 38°C
Using formula of heat
Put the value into the formula
We need to calculate the total heat
Using all heat amount
Put the value into the formula
Hence, The total amount of heat is 250.64 kcal.
