Which activity combines the use of conduction and convection to transfer heat?

The boiling of water in the iron pan is the activity in which both conduction and convention are used.

Energy is transferred from one part of the matter to other part in three ways:

Conduction is the movement of heat from the collision of the microscopic particles in the matter.

While convection is the transfer from the movement of fluids from one place to another.

In the water boiling activity, the pan is heated by the flame from taking the energy in the collision of atoms in the pan and the energy is transferred into the whole pan and eater molecules. This is conduction while in pan water movement from the bottom to top of pan is by convection.

The transfer of heat through molecules is known as conduction, so the radiator that contains energy is being transferred into the air molecules in contact with it and gradually when these air molecules start getting hotter, they vibrate vigorously and as they get heat up, they become less dense. This is because the air gets less dense, it will rise above the present air that is relatively cooler and denser which means it is heavier than the air that is heated. This concludes that there is a Convection taking place.

correct answer: biotic and abiotic limitations

carrying capacity is defined as the total number of an organism who can be supported in a given area within the natural resources limit and without harming or degrading the natural, economic or the cultural environment present for the future generations.

carrying capacity is determined by the limiting factors, which are known to affect the natural resources available. it may include water, nutrients, minerals, space, light etc.
