Question: Self-test 3.12 Calculate the change in G for ice at -10°C, with density 917 kg mº, when the pressure is increased from
1.0 bar to 2.0 bar.
1 answer:
The change in the Gibb's free energy per mole (G) is 1.96 J.
The given parameters:
- Density of the ice, ρ = 917 kg/m³
- Initial pressure, P₁ = 1.0 bar
- Final pressure, P₂ = 2.0 bar
- Temperature, T = - 10 C
- Mass of water = 18 g
The change in the Gibb's free energy per mole (G) is calculated as follows;

where;
V is the volume of the ice

Change in pressure;

The change in the Gibb's free energy per mole (G);

Thus, the change in the Gibb's free energy per mole (G) is 1.96 J.

Answer:
What type of question is this?
Explanation:
Is this a true or false question?
The angle subtended by the arc of movement of both chambers is the same. Thus:
S = r∅, for chamber A:
2.3 x 10² = 3.2 x 10² ∅
∅ = 0.72 rad
∅ is the same for B so:
S = 1.1 x 10³ x 0.72
S = 7.92 x 10² m
When the current flow ceases, the magnetic flow also decreases
I dont know what the statements are but concave lens are thinner in the middle which cause light to diverge or scatter
