What is the final temperature of the blocks once they reach thermal equilibrium? O 67.73°C O 43.40°C O 35.96°C O-347.34°C O 38.55°C What assumption do we make when solving calorimetry problems like this? O The substances are in a closed, isolated container that does not allow any energy to enter or leave the system. O Some of the energy transferred from one substance is lost to its surroundings and does not go to the other substance. O The two substances must have different specific heats. O We can only have two substances in thermal contact.
