a. If the temperature change of the dissolution of urea from your experiment were determined much lower than the actual temperature change, What is the effect on the value of entropy calculated from the incorrect data?

Explanation:

Before proceeding, we have to first understand the relationship between temperature and entropy.

From the equation of entropy which is given as;

ΔS = ΔQ / T

We can tell that entropy is inversely proportional to temperature.

This means that at constant heat, as the temperature increases, the entropy decreases and vice versa.

Inn this question, the temperature is much lower - a decrease. The effect that this would have on the value of the entropy is that it would be increased. A higher value of entropy would be recorded than the actual value of the entropy.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.
