The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3
<h3>Meaning of phase transitions</h3>
Phase transitions can be defined as the changing of matter from one form to another due to the addition or gaining of heat or due to the removal or loss of heat.
Phase transitions in matter are majorly between three phases which are: Solid, Liquid and Gas.
In conclusion, The arrows that represent the phase transitions in which heat energy is gained is : (A). 1, 2 and 3

Answer:
1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.
Explanation:
initially
4.9 atm 0
At equilbrium:
(4.9-2p) p
Pressure of nitrogen dioxide gas at equilibrium = 2.7 atm
So, (4.9-2p) = 2.7 atm
p = 1.1 atm
The value of equilibrium constant :
After addition of 1.2 atm of nitrogen dioxide gas more to the flask,will the reestablish an equilibrium in flask.
(2.7+1.2) atm 1.1 atm
At second equilibrium
(2.7+1.2-2x) atm (1.1+x) atm
The expression of :
Solving for x:
x = 0.3827 atm
The pressure of dinitrogen tetroxide after equilibrium is reached the second time:
(1.1+x) atm = (1.1+0.3827) atm =1.4827 atm ≈ 1.5 atm
1.5 atm is the pressure of dinitrogen tetroxide after equilibrium is reached the second time.

In the classroom eletrical energy used for the bulbs, fans, air conditioners and heaters.
Inert gases are gases that don't react with other elements. What this means is that they won't combine with other elements, and trigger chemical reactions. I've posted a picture of the Periodic Table. Take a look at the VERY LAST row, all the way on the RIGHT side of the table. That row is made of up NOBLE GASES (He, Ne, Ar, Kr, etc.) Those noble gases are INERT. They are non-reactive.
