j 2006 4- evaporation can happen at any temp. for boiling u need to reach the boiling point e.g water boils at 100c but it can evaporate at any temp, like room temp. how pressure affects, not sure but i will try. evaporation at any temp, means pressure can be differet, boiling for water at 100c, more pressure (in gas laws, when temp increase, pressure increase) one more point, during boiling temp doesn't change, means pressure is constant

may 2010:
4a- Matt black
4b- decrease on left hand, increase on right hand.
4bii- when temp rises, pressure increases. more heat absorbed by matt black, more temp rise, more pressure, air expands, push water down.
just the keywords, u can make a sentence from them ;)
