How does adding a solute ( use only one - salt or sugar) effect the time of water to change from a liquid to a solid?
Kruka [31]

Answer:

adding salt makes the water freeze slower and evaporate slower too.

Step-by-step explanation:

While pure water freezes at 0°C (32°F), salt water needs to be colder before it freezes and so it usually takes longer to freeze. The more salt in the water, the lower the freezing point.

ira [324]
Solve the area of the whole circle since in an hour, the minute hand covers the whole clock
assuming that the minute hand reaches all the way out to the edge of the clock


the minute hand is the radius
area=pi times r^2
r=5
5^2=25
area=pi times 25
area=25pi

aprox pi=3.14
25 times 2.14=78.5

area=78.5 in^2
