Heating Beakers Performance Task

Background:
Beakers A, B, and C contain water at 90 °C. There is half as much water in Beaker B as Beaker A and half as much water in Beaker C as Beaker B.

Directions: Using the simulation, conduct an investigation to predict the temperature of water in Beaker C after transferring 4 units of thermal energy from the beaker to its surroundings. In the simulation, you can transfer 1 unit of thermal energy from Beaker A or Beaker B to its surroundings each time you click the “Transfer thermal energy from beaker to surroundings” button. Observe what happens to the temperature and the particles in Beaker A and Beaker B when you transfer the thermal energy from beaker to surroundings. 

The initial temperature of water in Beaker C is 90 °C. What will its temperature be after transferring 4 units of thermal energy from Beaker C to its surroundings? (Please only write a number!)

How did you get your answer to number 1 above?

What is the relationship between mass and temperature change when the same amount of thermal energy is transferred? Use evidence from your investigation to support your answer. (Hint: "As mass decreases...)
