A solute adds particles to a solution, such as:
NaCl-> Na+ + Cl- This puts 2 particles in the solution for every 1 formula unit of table salt. Any particle that gets added to a liquid interferes with the liquids ability to form crystals (ice), it interferes with the liquids ability to break surface tension ( boiling), and since less liquid molecules can escape there is less vapor pressure.
Addition of a solute means:
To freeze the solution you would have to slow the molecules down more than normal to encourage crystal growth, so the temp must be lowered.
To boil the solution you would have to speed the molecules up more than normal to encourage the molecules to leave the liquid, so the temp must be increased.
To increase the vapor pressure of the solvent has the same explanation as boiling.
No, pressure affects the freezing point of substances. When you increase the presure, you lower the freezing point. So if you kept water at -4C then increased the pressure enough, the water would start to freeze
Different pressure systems.
Although a thermometer CAN be used its presence affects the temperature.

Tonicity
No, pressure affects the freezing point of substances. When you increase the presure, you lower the freezing point. So if you kept water at -4C then increased the pressure enough, the water would start to freeze
The factors that affect the freezing point of water are 1. pressure : the pressure on the liquid may alter the freezing point. 2. impurities : the impurities in water such as salt, sugar etc also alters the freezing point.
what is bed load particle size
Yes, the depth affects the freezing rate.
Elevation has minimal affects on the freezing point of water as it doesn't deal with gas molecules as boiling does. Elevation affects the boiling point of water because the air pressure changes with elevation.
Speed affects the frequency and pressure affects the wavelength.
A non-volatile solute affects increases osmotic pressure. This is a colligative property. There will be a higher osmotic pressure required to prevent the solvent from flowing into the solution because the solvent has a higher chemical potential without solute in it.
It is the energy that affects motion of particles, which are atoms and molecules.
Water is effectively an incompressible substance, so pressure does not affect its' volume. However, its boiling and freezing points are directly related to the external pressure. Water boils when its vapor pressure is equal to the external pressure (or the atmospheric pressure if it is contained in some uncovered pot). Greater external pressure requires higher temperature for water so as to have that value of vapor pressure for it to boil. This is how pressure affects water.
Particle size affects solubility. When particle size is small, the surface area per unit volume is larger, thus the solubility is increased.
It lowers the temperature where the mixture will freeze
as pressure increases, temperature increases
