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.
