Answer:
1.7 L
Explanation:
PV = nRT
If P, n, and R are constant:
V₁ / T₁ = V₂ / T₂
(2.0 L) / (293.15 K) = V / (255.15 K)
V = 1.7 L

kettle-power
Jun 18, 2014 — It's interesting to see how much energy heating and cooling systems use ... the kettle uses goes into the water it costs more to use electricity to boil ... 3 minutes is 1/20 of an hour, so 2.4kW for 3 minutes is equivalent to 2.4 / 20 = 0.12kWh. ... kettle should NOT clock over 1kw/h in the 4 minutes it takes to boil
Explanation:
Answer:
Explanation:
Since the fly accumulated a positive charge of +73pC, it must have lost an equal number of negative charge of -73pC to the surface (because the housefly was neutral to begin with).
Therefore, to answer our question we have to ask ourselves <em>how many electrons combine to make -73pC of charge? </em>
The answer is since one electron carries a charge of 
, the number 
of electrons that make up -73pC 
are
Thus, the housefly lost about 456 million electrons to the surface!
'Frequency' is a word that often confuses some people ... for no good reason.
It just means "frequent-ness" or "often-ness" ... how often something happens.
The SI unit of frequency is the Hertz (Hz). Hz means 'per second'.
So " 13 Hz " means 13 per second.
Here are examples of frequency:
-- 780 kilohertz (on your AM radio dial)
-- 98.7 Megahertz (on your FM dial)
-- 5.8 Gigahertz
-- twice a day
-- three per week
-- every 6 months
