A student added a sample of nh4no3(s) to water and measured the temperature over time. The data are shown in the graph above.

Sagot :

The values that the student should use to calculate the difference in temperature of the solution are; the final and initial temperature of the solution

Final and Initial Temperature of a Solution

From the attached image, to get the change in temperature that will be used to calculate the amount of heat given off or absorbed which we represent by q, we just read the initial and final temperature of the solution from the graph to get;

Initial Temperature of the solution; T_i = 24.8 °C

Final Temperature of the solution; T_f = 22.2 °C

Thus;

Change in temperature is calculated as;

ΔT = T_f - T_i

ΔT = 22.2 - 24.8 = -2.6°C

Thus, the values the student should use to get the difference in temperature are the final and initial temperatures
