According to the trend shown by the graph 750 ml of water should take approximately 20 minutes to boil? a. true b. false

True) 750 ml would take 20 minutes to boil

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.

this could be newton#'s law of cooling. the cooling curve is exponential
