Ice is the solid state of water, a normally liquid substance that freezes to the solid state at temperatures of 0 °C (32 °F) or lower and expands to the gaseous state at temperatures of 100 °C (212 °F) or higher.
Explanation:
The force required for the car is 5841 N
Explanation:
First of all, we need to find the acceleration of the car, which is given by:
where:
v = 27 m/s is the final velocity of the car
u = 0 is the initial velocity (the car starts from rest)
t = 6 s is the time the car takes to accelerate from u to v
Substituting, we find
Now we can find the force needed to accelerate the car; using Newton's second law of motion,
where:
F is the net force on the car
m = 1298 kg is the mass of the car
is the acceleration
Substituting, we find:

No chlorine will not react with potassium fluoride solution because chlorine reacts with water, forming HOCI and HCI. The only way for there to be a reaction when you add KF (Potassium Fluoride) to chlorine water is if there were any impurities in the water, even then it is doubtful that a color change would occur.
