Hello,
Question- Igneous rock can _____ to form metamorphic rock.
A. melt
B. harden
C. heat up
D. weather
Answer- Your answer is C. Heat up
Why- Any rock can become any rock igneous metamorphic or even condemnatory just by heating up but when it melts it becomes lava and the rock cycle starts all over again.
Important- If my answer was enough to help uou please mark me as Brainliest, Leave a thanks, and Rate my answer 5 stars thank you and have the best day ever!
Answer:
68.7% is the percent of frozen freshwater.
Convection is a type of heat transfer that is driven by the flow of liquid, or by a solid or weak material. These convection cells that flows in a circular direction are caused by the initial heating of earth's core. Earth is hot due to the original formation, and what keeps the heat circulating is radioactive decay. As unstable elements decay, they release energy and heat, which promotes convection cells in earth's mantle [hope this helps].
Answer:
This process, which is the opposite of vaporization, is called condensation. As a gas condenses to a liquid, it releases the thermal energy it absorbed to become a gas. During this process, the temperature of the substance does not change. The decrease in energy changes the arrangement of particles.
Answer : The value of ΔG expressed in terms of F is, -1 F
Explanation :
First we have to calculate the standard electrode potential of the cell.
or,
Now we have to calculate the standard cell potential.
Formula used :
where,
= Gibbs free energy = ?
n = number of electrons = 2
F = Faraday constant
= standard e.m.f of cell = +0.5 V
Now put all the given values in this formula, we get the Gibbs free energy.
Therefore, the value of ΔG expressed in terms of F is, -1 F
