My calculated value for the specific heat falls between the specific heat of the 20% solution and the 40% solution. I decided that the solution in my trial is the higher concentration, the 40% solution because it is more likely that my experimental value for the specific heat is higher than the actual value for my solution. Do you agree with Emma, or disagree. Provide reasoning and evidence from your own observations and measurements from the video.

PLEASE ANSWER THIS QUESTION IN A DETAILED CONVINCING AND SCIENTIFIC MANNER
Transcribed Image Text:3. Emma, a student, makes the following claim:
My calculated value for the specific heat falls between the specific heat of the 20% solution and the 40% solution. I decided that
the solution in my trial is the higher concentration, the 40% solution because it is more likely that my experimental value for the
specific heat is higher than the actual value for my solution.
Do you agree with Emma, or disagree. Provide reasoning and evidence from your own observations and measurements from the
video.
