Answer:
In refrigeration cycle heat transfer from inside refrigeration
In heat pump cycle heat transfer from environment
Explanation:
heat cycle is mechanical process use for cool the temperature but
In refrigeration heat transfer from inside of refrigeration that decrease temperature of refrigerator and in heat pump it decrease temperature negligible as compare to refrigerator
Its safe because it isn't something with electricity
Answer:
a. W = 51,194.54 kJ
b. W = 102,390 kJ
c. W = 153,585 kJ
Explanation:
a. the ground at 15°C.
=20°C = 273 K + 20 = 293 K
=15°C = 273 K + 15 = 288 K
W = 51,194.54 kJ
b. a pond at 10°C.
=10°C = 273 K + 10 = 283 K
W = 102,390 kJ
c. the outside air at 5°C.
=5°C = 273 K + 5 = 278 K
W = 153,585 kJ
Hope this helps!
