Closed system. In a closed system matter cannot enter or leave, but energy moves freely.
How fine do you want them categorized for the ranking ?
What's the population to be ranked ?
The 4000 naked-eye-visible stars ?
The stars within, say, 50 light years from Earth ?
All 200-400 billion stars in the Milky Way galaxy ?
All the stars in some other galaxy ?
Or did you have a list of items to be ranked that you decided not to share ?
That would be a lot like asking us to seat a class of sixth graders alphabetically,
and then not telling us their names.
And how do we drag one star on top of another ?
And if I do that here, how will you know about it ?
Answer:
Matter in its gas state has the most thermal energy than when it is a solid or a liquid. Because gasses have more thermal energy than others, they move differently than others.

Answer:
Explanation:
Heat absorbed by oil
= mass x specific heat x rise in temperature
= 30 x 10⁻³ x 950 x 2.2 x 10³ x ( 50-10 )
= 25.08 x 10⁵ J
Heat absorbed by air
= 50 x 1.2 x 1.0054 x 10³ x ( 20-10 )
= 6.03 x 10⁵ J
Total heat absorbed = 31.11 x 10⁵ J
If time required = t
heat lost from room
= .35 x 10³ t
Total heat generated in time t
= 1.8 x 10³ t
Heat generated = heat used
1.8 x 10³ t = .35 x 10³ t + 31.11 x 10⁵
1.45 x 10³ t = 31.11 x 10⁵
t = 31.11 x 10⁵ / 1.45 x 10³
t = 2145.5 s
Answer:
The trade winds, the prevailing westerlies, the polar easterlies.
Explanation:
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10). Fig. 3.10 only shows the circulation cells and winds in the Northern Hemisphere
