A refrigerator with an average cop of 2.8 used to cool a well-insulated container whose contents are equivalent to 10 kg of water, from 40'C to 10'C. The refrigerator consumes 400 W of electric power. Considering the specific heat of water as 4.2 kj/kgC, the time required to cool the water is ? my answer is 19 min. is it true ?

Yes, it is true

Explanation:

The computation of the time required to cool the water is shown below:

GIven that

Average cop = 2.8

Therefore the cooling effect is

= 2.8 × 400 W

= 1,120 W

ANd, the specific heat of water is 4.2 kj/kg°C i.e 4,200 j/kg°C

Now we assume the time is t

As we know that

t = 1,125 seconds

So, it would be 19 minutes

Therefore it is true

the clapeyron equation (also called the clausius-clapeyron equation) relates the slope of a reaction line on a phase diagram to fundamental thermodynamic properties.

explanation:

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.
