Equal masses of liquid water and liquid ethanol at room temperature are placed in separate, identical beakers. If the two beakers are heated at the same rate, based on the information given below, will ethanol or water reach its boiling point first?
Ethanol: c = 2.51 J/gºC, BP = 78ºC Water: c = 4.184 J/gºC
Hey! So remember a rule that states that the higher the specific heat capacity value, the smaller the Delta T, or the change in temperature. So that means that in this case water would require a smaller change in temperature. Therefore, it would take longer for ethanol to boil than it would take for water. This means that ethanol would reach its boiling point first. Hope this helped!
