Students have asked these similar questions
1. A thermometer placed in a solution undergoing a chemical reaction indicates an increase in temperature as
the reaction proceeds. Is this reaction endothermic or exothermic? Describe if heat energy is lost or gained
from the reaction (the system) to the surroundings. What is the sign of the enthalpy change (AH) of this
reaction?
2. A student performs a reaction and determines the enthalpy change (AH) to be 31.4 kJ. Will the
temperature of the surrounding solution increase or decrease as a result of this chemical process?
3. If you hold 3 grams of ice in your hand at room temperature, your hand will become cold. a) Is the reaction
H,O(s) –
H,O(1) endothermic or exothermic? b) In which direction does heat flow?
