Answer:
Where is question 12, we need it to answer this question
Explanation:
Explanation:
The given data is as follows.
q = -25.0 kJ, Pressure (P) = 1.50 atm
= (12 - 6) L = 6 L
Therefore, product of pressure and change in volume will be as follows.

= 7.5 L atm
= 
= 759.75 J
Now, we will calculate the change in internal energy as follows.

= 
= -25000 kJ + 759.75 J
= 24240.25 J
or, = 24.240 kJ (as 1 kJ = 1000 J)
Thus, we can conclude that the change in internal energy (
) for a system is 24.240 kJ.
Answer:
Earth's atmosphere is a mixture of nitrogen (79%), oxygen (20%), and a small fraction of carbon dioxide, water vapours and other gases. However, the atmospheres on Venus and Mars mainly consist of carbon dioxide.
