Chapter 1, Problem 3STP

Interpretation Introduction

Interpretation:

Reasonable conclusion for the experiment needs to be determined, if entire experimental data is correct.

Concept introduction:

Carbonated beverages include carbon dioxide dissolved in water. It is due to this gas that there are bubbles are fizzing in the liquid.

Answer to Problem 3STP

Correct answer: Option (a)

Explanation of Solution

Option (a) It can be seen in the graph that at $0°C$ the amount of $C{O}_2$ dissolved in the drink is $0.30g$ whereas at $25°C$ , the amount of $C{O}_2$ is $0.15g$. Thus, at lower temperature, $C{O}_2$ dissolves in greater amount. Thus, this is the correct answer.

Conclusion

Option (b) In the experiment performed by the student, temperature is continuously increasing with each sample and so the amount of $C{O}_2$ is decreasing. Thus, this is the incorrect answer.

Option (c) The higher the temperature, the higher is solubility of solids such as sugar dissolves easily in warm water than it dissolves in cold water. But dissolving of $C{O}_2$ is exactly opposite. The higher is the temperature, the lesser is the mass of $C{O}_2$ dissolved in the liquid. Thus, it is an incorrect answer.

Option (d). The higher is the temperature, the lesser is the mass of $C{O}_2$ dissolved in the liquid as it can be seen that at $25°C$, the amount of $C{O}_2$ is $0.15g$ Thus, it is an incorrect answer.
