Answer: this is not my own words :)

Learn how factors, such as exposure to the atmosphere, the composition of rock and climate affect the rate of weathering. Weathering is the mechanical or chemical process by which rocks are broken down. The weathering that happens to rocks can be understood by relating it to the digestion of a chocolate chip cookie

One of the factors that affects the rate of weathering is exposure to the atmosphere. ... Another factor that affects the rate of weathering is the composition of rock. Rocks are composed of minerals, which are solid substances found within rocks that have their own distinct chemical composition.

1 and 2 the forces holding water molecules together are stronger than the forces holding alcohols molecules together these forces are stronger in water due to hydrogen bonding the intermolecular forces forces that hold the water together are stronger than alchol because water has hydrogen bonding hydrogen bonding is hydrogen being attracted to oxygen or flourine or chloroine the electronegativity differences are larger the forces holding the bonds are stronger its like hydrogen is holding on to oxygen strongly different types of forces are lomdon dispersion forces like helium which have low boiling point they have nothing holding them together water has hydrogen bonds alcohol doesnt have the hydrogen bonds water has and geometry vsper model polar and hydrogen bonds as water so theyre weaker.

sattari [20]

Answer:

Step 1;

q = w = -0.52571 kJ, ΔS = 0.876 J/K

Step 2

q = 0, w = ΔU = -7.5 kJ, ΔH = -5.00574 kJ

Explanation:

The given parameters are;

P_i = 100 N·m

T_i = 327 K

P_f = 90 N·m

Step 1

For isothermal expansion, we have;

ΔU = ΔH = 0

w = n·R·T·ln(P_f/P_i) = 1 × 8.314 × 600.15 × ln(90/100) = -525.71

w ≈<em> -0.52571</em> kJ

At state 1, q = w = -0.52571 kJ

ΔS = -n·R·ln(P_f/P_i) = -1 × 8.314 × ln(90/100) ≈ 0.876

ΔS ≈ 0.876 J/K

Step 2

q = 0 for adiabatic process

ΔU = 25×(27 - 327) = -7,500

w = ΔU = <em>-7.5 kJ</em>

ΔH = ΔU + n·R·ΔT

ΔH = -7,500 + 8.3142 × 300 = -5,005.74

ΔH = ΔU = <em>-5.00574 kJ</em>
