Convection currents can happen in liquids and gases. For example when air is heated it becomes less dense and rises. This means that cooler more dense air comes down and is also heated rising up above more cooler air etc. This creates a convection current.
Here is a diagram of a hot water tank heater:

A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:
2NaBr + Cl2 = 2NaCl + Br2
Part 1 (non-ideal behavior ):
we will use Van der Waals formula:
P = (nRT/(V-nb)) - (n^2 a/V2)
when n (moles of H2) = 18 g / 2 = 9 moles
R (constant) = 0.0821
T(tempreature in kelvin = 20 +273 = 293 K
V(Volume) = 1 L
a (constant for H2) = 0.2476
b(constant for H2) = 0.02661
So by substitution:
∴P = (9*0.0821*293/(1-(9*0.02661))) - (9^2*0.2476/1)
∴P ≈264.6 atm
Part 2 (ideal behavior):
we will use the ideal gas formula :
PV = nRT
when we have n = 9
R= 0.0821
T=293 K
V= 1 L
∴P = (9*0.0821*293)/1 L
∴P = 216.5 atm

As the ball falls towards the ground, its gravitational potential vitality is changed into active vitality. The dynamic vitality of an item is the vitality it has because of its movement.
<u>Explanation:</u>
As the ball falls towards the ground, its gravitational potential vitality is changed into active vitality. The motor vitality of an item is the vitality it has because of its movement. At the point when the ball has arrived at its absolute bottom, its potential vitality is zero, and its motor vitality is more noteworthy.
Since vitality can't be crushed, the ball's most prominent potential vitality is equivalent to its most prominent motor vitality. K.E. = J, which is, obviously, equivalent to its underlying potential vitality.
