How was testing the electrical conductivity of the solution help tell the difference between salt and sugar?
There are a few different ways that you can test the difference between water, salt water, and sugar water. You can test boiling point for example.
What would be a good hypothesis for does sugar affect water evaporation?
The answer is yes, it does. Dissolved salt in water will lower the solution's vapor pressure according to Henry's Law. Evaporation rate is proportional to the difference in vapor pressure of the solution and the vapor pressure of the bulk gas phase over the water surface. I agree with the above answer as well except that the coldness of the surroundings is not a direct factor in determining the evaporation rate.
Why DOES THE rate of evaporation decreases when common salt is added to water?
The difference at room temperature is not significant.
How does the temperature affect ice melting with salt and sugar?
The salt will cause the ice to melt faster. the sugar shouldn't have much of a difference.
Salt water can be separated by evaporation?
Yes. You can separate water from a salt solution by evaporation.
How does salt and sugar water evaporation useful in the world?
Salt can be obtained by evaporation of sea water.
Does salt or sugar affect water evaporation?
salt evaperats faster than all of sugar and salt mixed and your mom ( . ) ( . )

What substances can be separated by evaporation?
For example a solid from a liquid; evaporation of water from sea waters give salt.
What is the effect of sugar and salt in the evaporation of water?
the water iwll evaporate leaving the salt and sugar then seperatee this using fractional distilation
Can water be used to separate salt from sugar why or why not?
A mixture of salt and sugar can be separated by using an organic solvent to dissolve the sugar. When the sugar is dissolved, it can be separated by filtering the salt from the liquid sugar,then recrystallise both solutions to from back their original crystals.
What effect does sugar and salt have on evaporation of water?
When use of 4oz - 5oz of salt, it speeds up the process of water evaporation in a glass at room temperature with sunlight.
What is the physical difference between salt and sugar?
salt is salty, sugar is sugary
What is the difference between sugar and salt?
Salt and sugar have different chemical appearences and shapes. Their taste is also different!
How do you separate a mixture of powdered salt and sugar?
Sugar burns when it is heated to a very high temperature. Salt does not burn.
Dose salt or sugar affect water evaporation?
No. The water is simply evaporated as normal and the salt or sugar (or pretty much any substance that can be mized with water) is left behind.
What would be a good hypothesis for does sugar affect water evaporation?
The answer is yes, it does. Dissolved salt in water will lower the solution's vapor pressure according to Henry's Law. Evaporation rate is proportional to the difference in vapor pressure of the solution and the vapor pressure of the bulk gas phase over the water surface.
