Answer:
Melting- The process by which a substance changes from its solid state to its liquid state.
evaporation- turning liquid into vapor.
Freezing- The process by which a substance changes from its liquid state into its solid state.
condensation- water which collects as droplets on a cold surface when humid air is in contact with it
sublimation- a solid deposit of a substance which has sublimed.

Answer:
1.44 atm
Explanation:
Step 1:
We'll begin by calculating the number of mole in 2,800,000 Liter of air.
I mole of air occupy 22.4L.
Therefore, Xmol of air will occupy 2800000L i.e
Xmol of air = 2800000/22.4
Xmol of air = 125000 moles
Step 2:
Determination of the pressure when the balloon is fully inflated .
This can be obtained as follow:
Number of mole (n) of air = 125000 moles
Volume (V) = 2800000 L
Temperature (T) = 120°C = 120°C + 273 = 393K
Gas constant (R) = 0.082atm.L/Kmol
Pressure (P) =.?
PV = nRT
Divide both side V
P= nRT/V
P= (125000x0.082x393) / 2800000
P = 1.44 atm
Therefore, the pressure of the air when the balloon is fully inflated is 1.44 atm
Everybody has a unique set of DNA that can only be identified to you. So, it can be certain that they have the right person if they study their DNA.
