intermolecular attractions and evaporate Chemistry.

I’m stuck on a Chemistry question and need an explanation. Two liquid compounds, A and B, have the same molecular weight.  Samples of A & B were placed on temperature probes and allowed to evaporate, as in today’s experimental procedure.  After 105 seconds, Liquid A had a ΔT of 10.2ºC, and liquid B had a ΔT of 3.7ºC.1.  Which of the two liquids required more energy to overcome intermolecular attractions and evaporate?  Explain your reasoning.2.  Which of the two liquids has higher intermolecular attractions?  Explain your reasoning.
