Physic Test
How to remember things before a test?
I have a physics test tomorrow and I'm the tenth grade, any tips?I've finished stuying though.
Go over your notes one more time right before bed tonight. Get a good night sleep and have a healthy breakfast tomorrow. That is the best way to score well- as long as you have already studied.

Farcry 2 Editor, physic test
Simple physic test (Level 1)?
After the aquaduct test which tricked most of you, this is a much simpler one
If a 3kW Microwave oven has 95% efficiency
How many seconds will it take to boil 200ml of water
The water is initially at ambiant temperature at 24°C
The experiment is made at normal atmospheric pressure
Assumption: no loss of energy in or through the receipient.
Please provide demonstration to get your 5 points.
This is basic physic and can be resolved through two equations.
AND MAKE SURE YOU USE THE RIGHT UNITS IN YOUR FORMULA!
3kW = 3,000 joules per second
3,000 joules x 0.95 = 2,850 joules per second
Delta T = 100C - 24C = 76C
200ml of water = 200grams of water
Specific heat of water = 4.184 j/g-C
Latent heat of vaporization of water = ~2,250j/g at sea level
Total energy needed to raise the temperature to 100C:
Q = mc(delta T) = 200g(4.184j/g-C)(76C)
Q = 63,596.8 joules
Total energy to boil 200g of water at 100C:
Q = m(LHV) = 200g(~2250j/g)
Q = 450,000 joules
A total of 513,596.8 joules
513,596.9 joules / 2,850 joules per second = 180.2 seconds
~3 minutes
