What are the independent and dependent variables in the following scientific investigation? Controlled variables are also being used in this investigation. Identify the controlled variables as well.

Question

A chemistry student is conducting an experiment to determine if table salt will dissolve faster in hot water or room temperature water. He will use a set measurement of salt placed in 100mL of room temperature water and compare the results to the same amount of salt placed in 100mL of hot water to determine which dissolved at a faster rate.

Answer 1

control: set amount of salt, set amount of water
Independent variable: temp of water
dependent variable: time to disolve

check my thinking.

Answer 2

Thank you so Very Much :))
