Answer:
P= 168258.30696 Pa
Explanation:
Given that
Mass of water vapor m = 19.00 g
Volume of water vapor V = 2.00 L
Temperature of water vapor is T = 111°C
= 384K
Molar mass of water is M = 18.0148 g/mol
Number of moles are
n = m/M
= (1.90 g)/(18.0148 g/mol)
= 0.1054 mol
Pressure inside the container is
P= nRT/V
P= 168258.30696 Pa
Answer:
Temperature, T = 10000 K
Explanation:
It is given that,
Wavelength,
We need to find the temperature of a star whose maximum light is emitted at this wavelength. It can be calculated using Wein's displacement law as :
T = 10000 K
So, the temperature of a star is 10000 K. Hence, this is the required solution.
Explanation:
Let us assume that the question says,"In a shower connected in summer and winter positions, with the following characteristics: 220V - 2200W / 4400W. Calculate the electric current that circulates at the lowest (summer) and highest (winter) power, with the same voltage. Tip: isolate the electric current in the expression P = Ix V
"
It is given that,
In a shower connected in summer and winter positions, with the following characteristics: 220 V - 2200 W / 4400 W.
It means lowest power is 2200 W and highest power is 4400 W
For lowest power,
I = electric current for summer
For highest power,
I' = electric current for winters
To stop the movement of Earth's tiny the inner core of the planet would have to lose loads of heat so it turns solid, then it would stop moving but if this happens we would lose lots of magnetic shield generated by the liquid metal near the core of the planet which protects from radiation the sun gives us.
Hope that helps!
