Explanation:
It would take 30 minutes
You would do 15.0 divided by 0.5
Answer:

Explanation:
Given:
volume of air in the room, 
temperature of the room, 
<u>Saturation water vapor pressure at any temperature T K is given as:</u>
<u />
<u />
putting T=298 K we have

<u>The no. of moles of water molecules that this volume of air can hold is:</u>
Using Ideal gas law,



is the maximum capacity of the given volume of air to hold the moisture.
Currently we have 80% of n, so the mass of 20% of n:

where;
M= molecular mass of water

is the mass of water that can vaporize further.
Answer:
1600 kJ/h per K, 888.88 kJ/h per °F and 888.88kJ/h per R
Explanation:
We make use of relations between temperature scales with respect to degrees celsius:

This means that a change in one degree celsius is equivalent to a change of one kelvin, while for a degree farenheit and rankine this is equivalent to a change of 1.8 on both scales.
So:
