Under which one of the following circumstances will heat transfer occur via convection? Group of answer choices Convection occur
s within metal objects. Convection only occurs in non-metallic solids. Convection occurs only within a vacuum. Convection occurs in the presence of a liquid or a gas. Convection can occur whether matter is present or not.
The answer is: Convection occurs in the presence of a liquid or a gas
Explanation:
Convection is a process by which heat is transmitted, either between two liquid or gaseous substances, provided they are at different temperatures.
Heat transfer occurs when there is a temperature gradient between the two bodies that are in direct contact; then, the heat flow flows from the hottest body to the least hot body. Liquids and gases are considered fluids.
Atoms are the components of ordinary matter, also called baryonic matter, which only represents 4% of the universe, while the remaining 96% would be formed by what is known as dark matter and dark energy which constitute two of the unsolved problems in physics.
