Transfer of heat in nature occurs through three ways: conduction, convection and radiation. Conduction takes place in solids. Convection in liquids and gases. Radiation takes place in all three media as well as in vaccum.
From higher temperature to lower temperature. If it is heating in a bowl it is same first bottom layer gets heated, and becomes lighter so it moves upwards, in the same way all the fluid moves over the lower temperature fluid.
Quite often, the main way would be convection. This is because the matter can move, or flow, fairly freely in both cases.
Heat transfer within a fluid takes place by convection currents.
When thermal energy is transferred, it is called a heat transfer. The particular type of heat transfer where thermal energy is transferred through a fluid is called convection.
Diffusion, same way it transfers through anything.
through particles that move past each other
When heat moves around in liquids, the mechanism is mostly convection.
convection currents
It is convection.
Convection
Convection is the transfer with in the fluid. If a container of hot liquid is touching something then it is conduction. If the heat is travelling through the air then it is radiation.
energy is transferred through moving currents of warmer air or liquid
Heat can be transferred through liquids and gases by means of conduction as well as conduction.The difference is that convection is not possible in solids.ConductionDuring conduction, heat is transferred due to the vibration of the molecules. A molecule at a higher temperature has more energy, and hence vibrates faster. It collides with other atoms and passes energy onto it. The chain continues and heat is transferred without any appreciable movement of molecules.ConvectionIn convection, the hotter particles move around in the fluid, transferring energy to the colder molecules. For example, when heating water in a vessel on a stove, the water at the bottom is heated first. It rises to the top and the cooler water flows down to be heated. This continues and heat is transferred throughout the fluid. Heat is transferred with the movement of molecules.
Heat is transferred into the metal spoon from the hot liquid, and it will soon be at the same temperature as the liquid because the spoon's heat capacity is quite small compared to the water surrounding it.

Convection
Radiation
When a fluid (liquid or gas) is heated, it expands. The heated fluid is therefore less dense than the fluid around it, so it rises.Colder fluid then sinks down to replace it and this sets up a movement of fluid called a CONVECTION CURRENT.

the liquid or gas must circulate to move the heat.
