Chapter 1, Problem 2STP

Interpretation Introduction

Interpretation:

The constant factor during the experiment performed by a student is to be determined.

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 2STP

Correct answer: Option (c) the amount of beverage in each sample is constant.

Explanation of Solution

Option (c) the amount of beverage in each sample. The student took the same carbonated beverage and the same amount but at different temperatures. Thus, it is constant.

Conclusion

Option (a) temperature. In the experiment performed by the student, temperature is continuously increasing with each sample. Thus, it cannot be constant.

Option (b) Mass of $C{O}_2$ dissolved in each sample. It is decreasing with the increasing temperature, thus it is not constant.

Option (d) Independent variable. There is no independent variable given. Thus it cannot be constant.
