How many grams of KCl remain in solution at 20 degrees celsius when a solution containing 80g of KCl in 200g of water at 50 degrees Celsius is cooled to 20 degrees Celsius?
To find the amount of KCl that remains in solution at 20 degrees Celsius, you can use the principle of solubility. Calculate the maximum amount of KCl that can dissolve in 200g of water at 20 degrees Celsius using a solubility chart. Once you have this value, compare it to the initial 80g of KCl to determine how much remains in solution after cooling.
What temperature is cooling minus 20 degrees or minus 70 degrees?
Cooling by 20 degrees would result in a temperature of -20 degrees. Cooling by 70 degrees would result in a temperature of -70 degrees.
What is the freezing point of water with a 5 percent salt solution?
The freezing point of water with a 5 percent salt solution is lower than the freezing point of pure water. The exact freezing point will depend on the type of salt used, but typically it will be around -6 degrees Celsius (21.2 degrees Fahrenheit).
What temperature in degrees celsius would cause sweating?
Sweating typically starts when the body's internal temperature reaches around 37 degrees Celsius (98.6 degrees Fahrenheit). This is the body's way of regulating temperature and cooling down through evaporation of sweat.
At noon the temperature was 18 degrees.If the temperature then dropped 4 degrees per hourwhat was the temperature at 4 pm?
The temperature at 4 pm would be 6 degrees. Starting at 18 degrees at noon, a drop of 4 degrees per hour for 4 hours would result in a decrease of 16 degrees, leaving a temperature of 6 degrees at 4 pm.

What is the boiling point for radiator fluid?
An pressurized automotive cooling system containing a 50/50 coolant/water mixture will boil at 236 degrees F.
What temperature is cooling minus 20 degrees or minus 70 degrees?
Cooling by 20 degrees would result in a temperature of -20 degrees. Cooling by 70 degrees would result in a temperature of -70 degrees.
What is the cooling property of water?
0 degrees C. , 32 degrees F.
What are the bond angles in a molecule containing SO2?
The bond angles in a molecule containing SO2 are approximately 120 degrees.
An angle containing 90 degrees is called?
A right angle
The radiator fan does not come on when the engine temp goes above 210 degrees The cooling temp sensor cooling temp switch and one fan relay has been replaced. The fans do activate when the ac is on.?
== == Cooling fans are designed to start at 235 degrees
When cooling food get to between 10 and 5 degrees in what time?
75
What solution which will not freeze at 0 degrees Celsius?
One solution that will not freeze at 0 degrees Celsius is a saturated salt solution, such as a solution of sodium chloride (table salt) in water. The addition of salt lowers the freezing point of water, preventing it from freezing at 0 degrees Celsius.
What is the bond angle in a molecule containing a CH3Br group?
The bond angle in a molecule containing a CH3Br group is approximately 109.5 degrees.
At what temperature does the cooling fan come on?
Usually between 220 and 230 degrees.
When does water start cooling down?
it freeze at 0degreesCelsius (which is 32 degrees Fahrenheit
