You start with two beakers that both contain 50 grams of solution. Beaker 1 contains water (the specific heat capacity for water is approximately 4.2 J/g °C). Beaker 2
contains alcohol (the specific heat capacity is approximately 2.2 J/gºC). Initially, both
solutions are at 20°C (about room temperature). Both beakers are then heated to 90°
C.
