Answer:
Explanation:
The equation of state (combined gas law) for an ideal gas states that
where
p is the gas pressure
V is the volume of the gas
n is the number of moles of the gas
R is the gas constant
T is the absolute temperature of the gas
The equation can be rewritten as
For an ideal gas that undergoes a transformation, if the amount of gas remains the same, the term on the right of the equation remains constant. This means that the ratio
for the gas remains constant, and therefore we can rewrite the equation as
where 1 indicates the initial conditions of the gas while 2 indicates the conditions of the gas after the transformation.

Answer:
the change in internal energy of the gases is -3.0924 KJ
Explanation:
The computation of the change in internal energy of the gases is as follows;
Given that
Q = -3.1 KJ
= -3100 J
It is negative as the heat is lost from the mixture
And,
W = + 7.6 J
It is positive as the work is done in the mixture
Now we use the following equation
Delat E = Q + W
= -3100 J + 7.6 J
= -3092.4 J
= -3.0924 KJ
Hence, the change in internal energy of the gases is -3.0924 KJ
Answer:
An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION.
