When the heat source is removed from a fluid, the fluid will cool down and its temperature will decrease. Depending on the type of fluid and the surrounding conditions, it may eventually reach equilibrium with its surroundings. Heat transfer will occur from the fluid to its surroundings until both reach the same temperature.
In a convection current, warm fluid rises due to its lower density and is replaced by cooler fluid. As the warm fluid rises, it transfers heat to the cooler surroundings, leading to circulation and the formation of a convection current.
The four basic elements of a heat exchanger are the hot fluid inlet, hot fluid outlet, cold fluid inlet, and cold fluid outlet. The hot fluid carries heat into the exchanger, transfers it to the cold fluid, and then exits the system. The cold fluid absorbs heat from the hot fluid and exits the system at a higher temperature.
When you heat gel, it may melt and become softer or more fluid. The heating process can break down the gel structure, causing it to lose its firmness and change texture.
During convection, heat transfer happens through the movement of fluid (liquid or gas) due to temperature differences. As the fluid near a heat source gets warmed up, it becomes less dense and rises, while cooler fluid sinks to replace it. This creates a continuous circulation pattern that helps to equalize temperatures within the fluid.
Convection heat transfer is the transfer of heat by the movement of a fluid.
Its solidifidation
The density of a fluid goes down (becomes less dense) when heat is applied.
The volume will increase as the fluid is warmed up.
Convection happens due to the transfer of heat by the motion of a heated fluid such as air or water.
Nothing actually happens to convection currents when heat is no longer supplied. The currents are produced by applying heat, most often to the bottom. The warmed fluid is 'lighter' than the cold fluid surrounding so it rises to allow colder fluid to replace it and be heated. As soon as the heat is removed, all the fluid rapidly comes to a single temperature and convevtion does not happen! An opposite effect happens when cold air sits on the surface of a lake. In this case the water at the surface cools, gets 'heavier' and sinks. In this case the convection currents operates downwards.
the liquid or gas must circulate to move the heat.

Heat conduction is the method that represents the transfer of heat in a fluid. Heat is transferred from particle to particle through direct contact within the fluid.
The heat pump circulates refrigerant fluid, which absorbs and releases heat as it moves through the system. This fluid is essential for the heat transfer process that allows heat pumps to efficiently heat or cool spaces.
The movement of heat by way of fluid is called convection. It involves the transfer of heat through the motion of the fluid particles.
Convection currents are the moving currents of fluid that transfer heat. Heat is transferred through the fluid as warmer, less dense fluid rises and cooler, denser fluid sinks, creating a continuous circulation pattern that transfers heat throughout the fluid.
