Problem: A student mixes 100 mL of 0.50 M NaOH with 100 mL 0f 0.50 M HCl in a Styrofoam® cup and observes a temperature increase of ΔT1. When she repeats this experiment using 200 mL of each solution, she observes a temperature change of ΔT2. If no heat is lost to the surroundings or absorbed by the Styrofoam® cup, what is the relationship between ΔT1 and ΔT2? a) ΔT2 = 4 ΔT1 b) ΔT2 =  2 ΔT1 c) ΔT2 = 0.5 ΔT1 d) ΔT2  = ΔT1
