Convection
Explanation:
Convection is form of heat transfer by which heat moves through liquid and circulates due to density differences.
There are three major forms of heat transfer:
- Conduction is form of heat transfer that involves contact between two bodies in which collision between their molecules caused heat exchange from the hot body to the cold one.
- Radiation is a form of heat transfer that does not involve contact. It involves the use of electromagnetic waves of different forms.
- Convection occurs in fluids in which heat transfers as a result of movement of molecules of the medium from one point to the other. The hotter body becomes lighter and rises whereas the colder ones sinks.

Answer:
An orbital is a region in space where there is a high probability of finding an electron.
Explanation:
The orbital is a concept that developed in quantum mechanics. Recall that Neils Bohr postulated that the electron occupied stationary states which he called energy levels. Electrons emit radiation when the move from a higher to a lower energy level. Similarly, energy is absorbed by an electron to move from a lower to a higher orbit.
This idea was upturned by the Heisenberg uncertainty principle. This principle state that the momentum and position of a particle can not be simultaneously measured with precision.
Instead of defining a 'fixed position' for the electron, we define a region in space where there is a possibility of finding an electron with a certain amount of energy. This orbital is identified by a set of quantum numbers.
