500 g of water at 90°C is cooled in a freezer. If all the water is converted to ice, what is the amount of heat released when th

KATRIN_1 [288]

Answer:

356 000 J

Explanation:

Total Energy released

= Energy released when water cools to 0 + Energy released when water is converted to ice at 0

= mcT + ml

= (0.5)(4200)(90-0) + (0.5)(334 000)

= 189 000 J + 167 000 J

= 356 000 J

A canister is filled with 310 g of ice and 100. G of liquid water, both at 0 ∘c . The canister is placed in an oven until all th

Here in the process we require

1. Heat to melt down all ice

2. Heat to raise the temperature of whole water to 100 degree C

3. Heat to boil off the water

now here for the first part

Heat required to melt the ice

$Q_1 = mL$

$Q_1 = 310*80 = 24800 cal$

now heat required to raise the temperature to 100 degree C

$Q_2 = ms\Delta T$

$Q_2 = (310 + 100)*1*(100 - 0)$

$Q_2 = 41000 cal$

Now heat required to boil it off

$Q_3 = mL$

$Q_3 = 410*540 = 221400 cal$

now the total heat required will be

$Q = Q_1 + Q_2 + Q_3$

$Q = 24800 + 41000 + 221400$

$Q = 287200 cal$

so it required 287200 calorie heat to boil it all water
