It assumes it is colder outside, since air flows from hot to cold naturally I believe

Im sorry, this is all the information I was given.

That makes sense. So in D, does mixing the two chemicals cause entropy to increase? I think it does but I'm not entirely sure.

So this would be due to D, where electrical energy is converted to entropy during the separation?

So the entropy would be greater in the room with dried air due to the sum of the water and air's entropy being lower than at the start?

They will be different temperatures because the water is extracted and the air reheated.

But will the water and air spontaneously recombine if allowed to? That didn't make sense to me, or maybe I just don't quite understand.

B? Because in order to pump heat from a cold surface to hotter surroundings electrical energy is required, which in turn will raise the temperature of the surrounding air?

Thanks for your help!

Homework Statement Keeping the cabaret door closed is important, so you install a sophisticated door control system that keeps the air exchange between inside and outside to a minimum. Why will such air exchanges always require the climate control system to work harder and consume extra...

Homework Statement When the air outside is very cold and dry, your climate control system must humidify the cabaret air so that the singers don't lose their voices. The climate control let's pure water evaporate into the dry air and raises the moisture content of that air. As this evaporation...

Whoops! Somehow read it backwards. With that change, would that then make C the correct answer since heat doesn't flow naturally from cold to hot.

Homework Statement Instead of pumping heat into the cabaret air from the outside air, you could simply put an electric space heater inside the cabaret. A space heater turns electrical energy directly into thermal energy. Why would operating a space heater consume more electric power than...

Homework Statement During the winter, your climate control system must begin warming the cabaret air so that the cabaret air is hotter than outdoor air. Amazingly enough, it can do this relatively efficiently by transferring heat from the outside air into the cabaret. However, your system must...

Homework Statement During the fall, the outside air's temperature is comfortable but its humidity is too high for direct use inside the cabaret. The air feels clammy and damp. So your climate control system chills the outdoor air to extract some of its moisture and then reheats that air back up...
