Heat spreads through liquids and gases mainly by.
A
Conduction
B
Radiation
C
Convection
D
Conversion
Explanation: 

Detailed explanation-1: -Convective heat transfer, often referred to simply as convection, is the transfer of heat from one place to another by the movement of fluids. The moving fluid carries energy with it. The fluid flows from a high temperature location to a low temperature location.

Detailed explanation-2: -Convection is the movement of heat by a fluid such as water or air. The fluid (liquid or gas) moves from one location to another, transferring heat along with it. This movement of a mass of heated water or air is called a current. Radiation is the transfer of heat by electromagnetic waves.

Detailed explanation-3: -The molecules of liquids and gases are not rigidly bound to each other and can move freely. This makes the transfer of heat by convection possible.

Detailed explanation-4: -Convection is the transfer of heat in liquids and gases. The hotter the liquid/gas the particles move faster and spread out. This means the gas/liquid becomes less dense. The less dense gas/liquid rises and the more dense gas/liquid sinks.

Detailed explanation-5: -Answer: In liquids and gases heat is transmitted mainly by convection .
