That statement is false
If the gaseous water molecules were greater than the liquid molecules ( which commonly happened if the temperature of the water is increased) , the water will evaporate
Answer:
Tectonic plates
Explanation:
All the natural disasters like earthquakes, volcanoes and geysers appear throughout the region of New Zealand because of the movement of tectonic plates underneath the surface. New Zealand rests on the edges of two tectonic plates including the Pacific and the Australian plates.
a) Answer:
= 210,000 gram or 210 Kg
Explanation:
14 hr is equivalent to;
= 14 × 3600 s
But;
8.2x10^4 A = 8.2x10^4 Coulomb /second = 8.2x10^4 C/s
1 Faraday = 96485C
Molar mass of Li: 6.941 g/mol
Therefore;
{(8.2x10^4 C/s)×(14×3600s)×(6.941 g/mol)/(96485C/mol)}×70%
= 2.1x10^5 gram or 210 kg
b. Answer;
= 0.23 kWh/mol
Explanation and solution;
Energy per mole is given by;
(96485C/mol) × (8.4V) = 8.10x10^5 (J/mol)
= 8.10x10^5 (Ws/mol)
Divide by 3600s/h to get:
= 8.10x10^5 (Ws/mol)
= 225 Wh/mol
= 0.23 kWh/mol
