Answer: 5040 joules
Explanation:
How much energy is released when 150g of silver cools from 220°C to 80°C?
Given the following :
Mass (m) of silver = 150g
Change in temperature (ΔT) = (220 - 80)°C = 140°C
Q=mcΔT
Where Q = quantity of heat
m = mass of silver ; c = specific heat capacity
Specific heat capacity of silver = 0.240 j/g°C
Q = (150 * 0.240 * 140)
Q = 5040J
The Moon of the Earth has some similarities, but also lot of differences with the other natural satellites in the Solar system.
The Moon is rocky, covered with dust, has lot of craters from asteroids and meteorites. Most of the planets in the solar system are actually gassy, frozen, and the craters tend to be very rare.
Compared to the planet around which it spins, the Earth, the Moon is actually very large, even though it is nowhere as large as some other moons in the Solar System. All the other moons tend to be much smaller in comparison the the planets around which they spin.
The Moon also has very low gravitational pull and very small mass for its size, and the reason for that is still not clear. All the other moons have gravitational pulls and masses that are expected by their size.
The longest river is The Yangtze River in China is the longest river in Asia.<span> It flows for 3,915 miles, or 6,300 kilometers. This length makes it the third-longest river in the world after the Nile and the Amazon.</span>
I think that the answer is Buddha
Not too sure! Sorry:(
