There are four Earth's spheres: the geosphere, hydrosphere, biosphere and atmosphere.
The spheres interact with one other. For example, plants (biosphere) produce oxygen (atmosphere) from carbon dioxide (atmosphere).
Substances in different spheres are recycled and turned into other phases and forms. This is important cycle and without that, there is no life on Earth.
<span>The answer is hypertonic. In osmosis, water
molecules move from a hypotonic solution to the hypertonic solution, through a
semipermeable membrane. This occurs until
both solutions become isotonic relative to each other. In osmosis, only
the movement of water molecules occurs since the ions are large enough to pass
through the pores of the semipermeable membrane,
in this case, the cell membrane. Due to
loss of water in the process of osmosis, the cells in the fingers of the swimmers
shrunk hence looked shriveled.</span>
Steam to water would be condensation
Answer:
3.1°C
Explanation:
Using freezing point depression expression:
ΔT = Kf×m×i
<em>Where ΔT is change in freezing point, Kf is freezing point depression constant (5.12°c×m⁻¹), m is molality of the solution and i is Van't Hoff factor constant (1 For I₂ because doesn't dissociate in benzene).</em>
Molality of 9.04g I₂ (Molar mass: 253.8g/mol) in 75.5g of benzene (0.0755kg) is:
9.04g ₓ (1mol / 253.8g) = 0.0356mol I₂ / 0.0755kg = 0.472m
Replacing in freezing point depression formula:
ΔT = 5.12°cm⁻¹×0.472m×1
ΔT = 2.4°C
As freezing point of benzene is 5.5°C, the new freezing point of the solution is:
5.5°C - 2.4°C =
<h3>3.1°C</h3>
