What causes the particles of a substance to be in one particular phase rather than another?
The phase of a substance is dependent on several things. Most basically, the composition of the substance itself and the strength of the atomic interactions within the substance determine how the other factors will effect it. For example, these interactions determine that water is liquid and steel is solid at room temperature. Substances changing phase depends on the temperature and the pressure exerted on them. The higher the temperature, the closer a substance gets to a gaseous phase. The lower the pressure, the same. This is the reason why water boils at a lower temperature if you are at a significantly higher elevation: there is less pressure. An interesting concept which has cool applications is that of a "triple point." Use Google to find a graphic image, so you can more easily figure out what I am saying. The triple point is the place at which the three phases meet, and each substance has its own triple point at a unique temperature and pressure. Below this point in temperature, pressure, or both, a substance will skip the liquid phase entirely and go directly from a solid to a gas, as in the case of "dry ice."
How does specific latent heat of water vary with temperature?
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.
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
How does temperature effect a volume of air?
Temperature is not directly tied to volume, its related to pressure. Increasing the temperature will increase the pressure--only if volume is held constant. That is were volume and temperature are related, through pressure. However, if you increase the volume it does not change the temperature.
Does the temperature of the water change the boiling point?
The boiling point of water depends only on pressure, not ambient temperature. The only correlation between climate temperature and boiling point would come about from the fact that cold climates in temperate parts of the Earth are usually at higher elevations than warmer climates and therefore have lower atmospheric pressure.
What does a phase diagram provide?
"A phase diagram is a graph of pressure versus temperature that shows in which phase a substance exists under different condition of temperature and pressure" -Glencoe Chemistry Book
What information does a phase diagram give?
The effect of temperature and pressure on the phase of a substance
What affects the solubility of a substance in water?
temperature, pressure, presence of other chemical species (for the same solute and the same solvent)
What temperature will a substance melt if the atmospheric pressure is 1.2?
Leaving aside the obvious deficiencies in the question (1.2 WHAT? What substance?)... For most substances pressure has only a tiny effect on the melting point, and enormous pressures are required to change the melting point significantly (in contrast to boiling point, where pressure has a relatively much greater effect).
How you will you explain pressure belts and winds diagram?
The Coriolis effect explains this phenomenon clearly. Pressure belts and wind belts differ in patterns depending on certain atmospheric factors like temperature.
Why does temperature effect the physical state of matter?
a low temperature will freeze the substance, a high temperature will melt or turn the substance into vapor
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
What physical effect can change the boiling of substance?
Pressure
Can pressure affect solubility of a substance in a solution?
Pressure can affect the solubility but the effect is not important.
What is the effect of temperature on gases in liquids?
It is varied for each substance.
What 3 factors affect the density of sea water?
Temperature, pressure, and common ion effect
What is the effect of temperature change on the pressure of a contained gas?
When temperature increases, pressure also increases.
