Answer with explanation:
Each of the three gases were heated such that the initial temp and final temp for each gas were noted as follows:
A. -21 -8
B. -12 12
C. -19 -15
a)
The difference in the overall temperature is:
Gas A: -8-(-21)= 13
Gas B: 12-(-12)= 24
Gas C: -15-(-19)= 4
b)
The change in temperature will be negative:
Because the heating of a gas and cooling of a gas are reverse process and when the gases were heated the change was positive ( As seen in part a) ) and hence when they will be cooled the change in temperature will be negative.
Answer:
Overall change in temperature.
If the gases are cooled the overall change in temperature will be negative.
Step-by-step explanation:
We are given the following information in the question:
Records the temperature of some gases that are being heated.
Gas Initial Temperature Final temperature
A -21 -8
B -12 12
C -19 -15
Overall Change in temperature =
Final temperature - Initial temperature
[tex]A: -8-(-21) = 13\\B: 12-(-12) = 24\\C: -15-(-19) = 4[/tex]
If an experiment is created in which the three gases A, B and c are cooled down, the change in temperature would be negative because after cooling down the gases their final temperature will be less than the initial temperature and as a result the overall change will be negative.
In the above case the overall change is positive as the gases are heated so the final temperature is greater than the initial temperature.
