Energy is equal to motion over speed
Protons and neutrons are made up of tiny particles called quarks.
A proton is a baryon made up two Up and one Down quark.
A neutron is made of two Down quarks and one Up quark.
The Up quarks possess a 2/3 positive charge while the Down quark possess a 1/3 negative charge.
When we refer that a proton consists of two Up quarks and a Down, this simply means that its net appearance matches this description.
It is thought that quarks themselves are surrounded by gluons.
Gluons are the basic particles underlying the strong interaction between protons and neutrons in the nucleus.

Water steam condenses if its pressure is equal to vapor saturation vapor pressure.
Use the Clausius-Clapeyron relation.
I states the temperature gradient of the saturation pressure is equal to the quotient of molar enthalpy of phase change divided by molar volume change due to phase transition time temperature:
dp/dT = ΔH / (T·ΔV)
Because liquid volume is small compared to vapor volume
ΔV in vaporization is approximately equal to to the vapor volume. Further assume ideal gas phase:
ΔV ≈ V_v = R·T/p
Hence
dp/dT = ΔHv / (R·T²/p)
<=>
dlnp/dT = ΔHv / (R·T²)
If you solve this DE an apply boundary condition p(T₀)= p₀.
you get the common form:
ln(p/p₀) = (ΔHv/R)·(1/T₀ - 1/T)
<=>
p = p₀·exp{(ΔHv/R)·(1/T₀ - 1/T)}
For this problem use normal boiling point of water as reference point:
T₀ =100°C = 373.15K and p₀ = 1atm
Therefore the saturation vapor pressure at
T = 350°C = 623.15K
is
p = 1atm ·exp{(40700J / 8.314472kJ/mol)·(1/373.15K - 1/623.15K)} = 193 atm

The law of conservation of energy states that energy can neither be created nor destroyed.
It can only be converted from one form of energy to another.
I hope this helps! ❤️
