Ascience student observes that a dissolvable antacid tablet acts faster in relieving stomach pain when taken with warm water than when taken with water at room temperature. based on the observation, suggest a potential problem that can be studied. also, list the dependent, independent, and controlled variables that can exist in such an investigation. ( answer quickly)

1. Based on the observation, suggest a potential problem that can be studied.

The research is trying to observer the effectifity of the drug to relieve stomach pain. Pain is subjective and it could not be compared equally for different people. The potential problem would be how you will grade the time objectively as the threshold of when the pain considered relieved might not be same for different subject. If not, you have to observe the drug for the same patient.

2. Also, list the dependent, independent, and controlled variables that can exist in such an investigation.

Dependent variable is the time needed for the stomach pain to be relieved. The independent variable is the temperature of the water used. The controlled variable could be the age, gender, cause of the stomach pain, or other medical condition of the subject. The drug type and doses should be controlled too.
