Question

What was the heat flow for the water (qH₂O) in Joules in the calorimetry lab?

a) Insufficient data
b) Endothermic
c) Exothermic
d) 0 J (zero)

Answer 1

The heat flow for the water in the calorimetry lab can be either endothermic or exothermic, depending on the specific experiment.

Step-by-step explanation:

The heat flow for the water (qH₂O) in the calorimetry lab can be either endothermic or exothermic, depending on the specific experiment. In an endothermic process, heat is absorbed by the water from the surroundings, resulting in a positive heat flow. An example of an endothermic process is when ice melts. In an exothermic process, the water releases heat to the surroundings, resulting in a negative heat flow. Examples of exothermic processes include the combustion of fuel or the dissolution of an acid in water.
