c) only from warmer areas to colder areas.
The second principle of thermodynamics states that heat can only flow from a hotter body to a cooler one. Specifically, Clausius statement says that is not possible for heat to move by itself from a lower temperature body to a higher temperature body.
Answer:
x=0.8
Explanation:
Defining our values we have
Where 
is the pressure of the super heated steam
is the Temperature of the super heated steam
and 
is the pressure in an adiabatic process.
State 1
State 2
Note that here in state 2 the process is Reversible.
At the value where 
we have
Through this values we can calculate the Fraction of steam,
Answer:
Copper's composition does not change as its shape changes, hence it is a physical feature.
Explanation:
<span>So we want to know what is not influencing the phases of the Moon. What influences Moon phases are celestial bodies that are close enough to have enough gravitational force to have an influence. Those celestial bodies would be the Earth and the Sun, since moon itself cant influence itself and all other stars are too far to exert gravitational force. So the correct answer would be the Moon and the stars do NOT have an influence on the Moon phases. </span>
Straight lines is my best answer
