Heat is always transferred through the movement of matter in the convection mode of heat transmission.
<h3>What is heat transfer ?</h3>
Heat transfer is the movement of heat from one solid or liquid item to another. Always, heat moves from one body with a greater temperature to one with a lower temperature. To put it another way, heat always transfers from a hotter body to a cooler body.
- Heat energy is transferred through the mechanism of conduction when nearby atoms or molecules collide. In solids and liquids, where particles are more closely spaced, conduction happens more easily than in gases, where particles are more widely spaced.
- Here we can say that heat is transfer when there is movement between two books and hence there is change in temperature.

<h2>
Hello!</h2>
The answer is:
The buoyant force is equal to 49N.
<h2>
Why?</h2>
The buoyant force is the force that pushes upwards and object when it's submerged in water, this force is always trying to move the object to the surface of the liquid or water. We must consider that the volume of water or liquid displaced is equal to the volume of the submerged object.
We can calculate the buoyant force using the following formula:

Where,
Density is the density of the water or liquid.
Volume displaced is equal to the volume of the submerged object.
Gravity acceleration is the acceleration due to gravity.
So, from the statement we know that:

Now, substituting and calculating we have:




Hence, we have that the correct answer is:
The buoyant force is equal to 49N.
Have a nice day!
The charge? If you mean valance electrons, the answer is 8. All compounds must be equal to that of a noble gas.
