For a closed system, the change in entropy for a reversible process is _________ the change in entropy for an irreversible proce ss between the same two states
1 answer:
Answer:
c. the same as
Explanation:
for a closed system:
⇒ ΔS > 0.....irreversible process
⇒ ΔSrev = ∫ dQ/T
for an irreversible process, ΔS is not the same as in a reversible process, since more than one reversible process is needed for the two ΔS to be equal.
⇒ ΔSirrev = ΔSrev1 + ΔSrev2 + ....
but if the initial and final states are the same, ΔS for an irreversible process can be calculated as if it were a reversible process.
⇒ ΔSirrev = ΔSrev

<h2>Giant impact and metalcore.</h2>
Explanation :
Mercury has a large core of liquid metal. The metal core is of iron metal. The core is surrounded by a mantle which is made up of silica and a solid outer crust. In the case of Mercury, the total core percentage is 42% of the planet while the Earth's core is only 17% of the planet. Mercury has lost part of its mantle and crust that left the mercury with a large metal core.
It is letter C: Continental crust is thicker than oceanic crust.
Answer:
Explanation:
70% (vol/vol) means
cotnaimns 70 %(vol/vol) 70 ml of isoprapnol is there in 100 ml of Rubbing sold alcohol.
if it is 200 ml then obvouly it has the 70*2 =140 ml of isoproanol required.
Choice c - eats away other materials
