Student A measured the heat capacity of an insulated calorimeter and reported a value of -247.7 J/°C. Student B did the same experiment and reported a value of 156.7 J/°C. Which statement(s) represent(s) valid conclusions about this experiment? O Student B was correct to conclude that a value of 156.7 J/°C is reasonable. This value supports our hypothesis that a thermal insulator will need to absorb a relatively large amount of energy in order to increase its temperature by 1°C. O Student B was correct to conclude that Student A had an error in their experiment or their calculations because the heat capacity value being reported by Student A would imply that the calorimeter was absorbing energy resulting in a decrease in temperature. O Student A was correct to conclude that a value of -247.7 J/°C is reasonable. This is because it supports our hypothesis that a thermal insulator will need a relatively large change in energy to produce a 1°C change in temperature. O Student A was correct to conclude that the value of 156.7 J/°C reported by Student B is unreasonable. This is because calorimeters always release energy into the system, therefore the heat capacity should have a negative value.

POST-QUESTIONS 1. After a student dissolved 0.5 g of white solid in water, she tested the conductivity and determined that the solution did not conduct electricity. The student then concluded: "when the white solid dissolved it 'just disappeared' so some sort of error must have been made because all solids are ionic compounds and, therefore, are electrolytes." Comment on the student's conclusion. Is her statement a valid conclusion? If so, identify what is correct. If not, write a conclusion that would be correct.
