1. An experiment occurs where 800 J of thermal energy are absorbed by a sample of water in a highly insulated environment. In a second experiment 800 J are absorbed by another sample of water that has three times the mass as the first, in a similar environment. In each case a temperature reading is made before the energy is absorbed and then again after the energy is absorbed and distributed throughout the sample (equilibrium reached). a. Will the change...
