Gold! it's boiling point is 2807 according to this chart:
http://www.lenntech.com/periodic-chart-elements/boiling-point.htm
The heat required to vaporize 43.9 g of acetone at its boiling point is calculated as below
the heat of vaporization of acetone at its boiling point is 29.1 kj/mole
find the moles of acetone = mass/molar mass
= 43.9g /58 g/mol =0.757 moles
heat (Q) = moles x heat of vaporization
= 29.1 kj/mole x 0.757 moles = 22.03 kj
It would 3 because if you read it tells you the answer
Answer : A and D shows PROCESS of sweating
