Colligative
properties calculations are used for this type of problem. Calculations are as
follows:<span>
ΔT(freezing point) = (Kf)m
ΔT(freezing point)
= 1.86 °C kg / mol (0.50 mol/kg)
ΔT(freezing point) = 0.93 °C
Tf - T = 0.93 °C
<span>T = -0.93 °C</span></span>

Answer:
Static charge is caused by the build up of electrons on the atoms of an object.
Explanation:

Rub it against your head in order to disassociate electrons from it, causing it to be charged - you can now put it on a wall and notice how it 'sticks' to it. You can also cause this effect by jumping on a trampoline, causing static charge to be built up - which is sometimes why you feel a little 'zap' when you touch the sides of it.

centi- is essentially 10^2 of one meter.
If you had 100m, multiplying 100 by 10^2 (or 100) would give you 10000 cm.
