The property to be used is sieving. you get a bowl and a sieve when you pour the sand and salt,the salt being the small particle sieve to the bowl while the sand remain on the sieve as residue
Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by lowering the atmosphere or external pressure.
The boiling point is the temperature at which the vapor pressure of liquid equals the external or atmosphere pressure.
So, if you decrease the external pressure the temperature needed for the liquid reach the lower external pressure is also lower..
You can accomplish by taking the water to higher levels in the Earth (atmosphere pressure at high altitudes is lower than at sea level) or by creating vaccum.
Answer:
Explanation:
Hello, since the Gibbs' phase rule states the following equation:

Whereas C is the number of components and P the present phases, you answers are:
1. F=1-2+2=1.
2. F=2-2+2=2.
3. F=2-2+2=2.
Best regards.
