Question

9. A reaction in a beaker absorbs 250 Joules of energy. According to the Law of Conservation of Energy, the energy that the environment releases is 250 J. What will happen to a thermometer placed in the reaction?A. Temperature will decreaseC. Temperature will increaseB. Temperature will stay the same D. Not enough information

Answer 1

C. Temperature will increase

Step-by-step explanation:

The Law of Conservation of energy explains that in a isolated container, energy can neither be created nor destroyed, it can only be transformed into another form of energy and it would have the same amount of energy, unless added from outside.

So, in this case, the temperature in the thermometer will increase, because the beaker absorbs energy.
