What else can I help you with?
Compared to the pure water an aqueous solution of calcium chloride has a?
Higher boiling point and a lower freezing point. These are called colligative properties. When a solute is put into solution with the solvent, there is a change in the vapor pressure, osmotic pressure, elevation of the boiling point, and depression of the freezing point.
How do altitude affect freezing melting and boiling points of water?
As altitude increases, the air pressure decreases. This results in lower boiling points for water because there is less atmospheric pressure pushing down on the water. However, the freezing point of water is not significantly affected by altitude.
What is the effect of salt in boiling and freezing temperatures?
The freezing point is lower and the boiling point is higher.
What is the effect of decreased pressure on boiling point and freezing point of water?
Decreased pressure lowers the boiling point of water because it reduces the pressure exerted on the liquid, allowing the water molecules to escape into the vapor phase more easily. However, decreased pressure has a less significant effect on the freezing point of water compared to the boiling point, as freezing point is more influenced by the presence of impurities in the water.
Is it true that the boiling point of a liquid remains constant at all altitudes?
No. Atmospheric pressure falls the higher you go. The boiling point of a liquid varies with ambient pressure. If the pressure is lower then the boiling point will be lower.
What is the effect of decreased pressure on the boiling and freezing point?
As pressure decreases, the boiling point of water will also decrease. Backpackers camping in the high mountains are familiar with the phenomena when they get water boiling - and find that it is still only lukewarm because the atmospheric pressure at their high altitude is so low.
When compared to pure water what will a 0.5 M solution of potassium chloride have a. lower boiling point b. lower freezing point c. higher capor pressure d. lower osmotic pressure?
b. lower freezing point A 0.5 M solution of potassium chloride will have a lower freezing point compared to pure water due to the presence of solute particles which disrupt the formation of ice crystals.
Why is boiling dependent on pressure?
Boiling is dependent on pressure because the pressure affects the boiling point of a substance. When the pressure is higher, the boiling point of a substance is also higher, and when the pressure is lower, the boiling point is lower. This is because pressure affects the vapor pressure of the substance, which needs to equal the atmospheric pressure for boiling to occur.
What is the effect of pressure on boiling?
Lowering the pressure the boiling point is also lower.
How does the presence of a solute affect the freezing and boiling points of a solvent?
They usually lower freezing points, think antifreeze. And salt water freezes at a lower temp than fresh, that is why they put salt on ice. And they raise boiling points, think salt in water when making spaghetti. Or, again antifreeze.
In the Fahrenheit temperature scale what is the boiling point of water?
In atmospheric pressure (ie at sea level), water boils at 100 degrees Celsius.
Why are the freezing melting and boiling points lower on high altitude?
Heat is only energy. In areas of low pressure, such as high altitudes, "heat" particles, which are charged electrons, escape more quickly. As more "heat" (electrons) escapes more quickly, things freeze more quickly. As far as I know melting and boiling points are higher, not lower in high altitudes.
