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.
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 variables that responsible of the three phases of matter?
The variables responsible for the three phases of matter are temperature and pressure. In general, increasing temperature tends to transition matter from solid to liquid to gas, while increasing pressure can have the opposite effect. These variables influence the arrangement and movement of particles in a substance, leading to the different phases.
What is the solubility of a substance is lowered because of this?
If the solubility of a substance is lowered, it means that less of the substance can dissolve in a given solvent at a specific temperature. This could be due to factors such as a decrease in temperature, a change in pH, or the presence of a competing solute that forms a complex with the substance.
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 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.
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.
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 physical effect can change the boiling of substance?
Pressure
What affects the solubility of a substance in water?
Several factors affect the solubility of a substance in water, including temperature, pressure, the polarity of the substance and water molecules, and the presence of any other solutes in the solution. Generally, the solubility of most substances increases with higher temperature but can vary depending on the specific chemical properties of the substances involved.
Can pressure affect solubility of a substance in a solution?
Pressure can affect the solubility but the effect is not important.
What is the manipulated variable in density?
In the context of density, the manipulated variable is the factor that is intentionally changed or controlled in an experiment to observe its effect on the density of a substance. This could include variables like temperature, pressure, or composition of the substance.
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
