The particles in a solids and liquids are tightly packed together so as pressure increases nothing much can happen(since participles can't move closer to each other).
gas phase
Dissolving (as such) of solutes in a solvent is physical.
Gas under pressure is a physical change not a chemical change because the gas is not being affected chemically (atoms are not bonding to other atoms and etc.). Pressure only forces the gas particles to be closer together, possibly reverting them to liquids if the temperature is low enough.
A physical change. The chemical make up of the material is not changed. --------------------------------------------------------------------- Pressure is not a change, it is a characteristic. It is the ratio force/area.
Increased pressure is a physical change, not a chemical change - even if the increase in pressure is itself the result of a chemical process.
The change in pressure is highly affected by altitude.
gas phase
They can change by lowering the freezing point.
Atmospheric pressure and the presence and concentrations of solutes affect the freezing point.
Solutes raise and lower the boiling points of solvents. :)
Life on Earth is greatly affected by pollution because it causes animal and plant deaths, together with a change in the environment that damages all ecosystems.
beause they contain some proteins called porins that show little permeability for hydrophilic solutes. these porins vary/change their structure to escape from antibacterial pressure or regulation.
The speed of sound is not greatly affected by pressure in an ideal gas. Air is not an ideal gas, so there may be some small effect, but temperature and humidity will be much more influential. ================================ Answer #1: The frequency of sound is completely determined by the source of the sound. Once the sound leaves the source, the frequency doesn't change.
No, dissolving solutes in a solvent is always a physical change!
Latent heat of water is the heat required to change its state at a particular temperature BECAUSE of the pressure at which the water is at at the point of fusion or evaporation.The latent heat is not affected by temperature (in fact there is no temperature change during absorption of latent heat) it is affected by the pressure acting on a substance. As the pressure increases, the latent heat (of evaporation) decreases, consequently with the change in pressure there is also a different temperature at which the evaporation takes effect, higher pressure, higher temperature at the evaporation point.
Maybe, maybe not. You would need to specify the nature of the solutes, the permeability of the membrane to each, and the pressures involved.
Coral reefs are very sensitive to their environment and are greatly affected by pollution. They are also impacted by climate change, which has been cited as a cause of coral bleaching.
