Answer:
The answer is convection.
Explanation:
There are three types of heat transfer: conduction, convection and radiation.
- Conduction occurs when two objects touch each other and transfer heat.
- Convection occurs when an object heats its surrounding fluid (like air, or water) and, since the hot fluids are less dense than the cold ones, they go up. So convection is a type of heat transfer that usually goes from down to up.
- Radiation occurs when objects emanate heat in the form of electromagnetic waves that propagates in all directions.
So in this case, when the marshmallow is above the fire, it is exposed to convection, which does not occur when it is on the side of the fire.
Acceleration I’m pretty sure
Answer:
2.49 V.
Explanation:
The formula which relates the equilibrium condition in the electrochemical cell is,
Given that the number of electron is 3 and the value of is 0.652 V.
Now put these values in above equation.
Therefore, the value of Keq for an electrochemical reaction is 2.49 V.
