Question

The diagram shows currents that form as water is heated. Which would most likely contain this same type of current? a.the air above a wildfire b.a carton of milk in a refrigerator c.a snowdrift on a shady mountainside c.a boulder in a hot desert

Answer 1

The air above a wildfire.

Answer 2

The right answer is a. The air above a wildfire.

Three methods allow the applicabe thermal transfer to heat the water.

CONDUCTION HEATING:

* The principle of conduction is probably the simplest heating system to understand.

* This process is based on a heat transfer by the contact between two media of different temperature.

* One hot element will warm another element when they come into contact.

* For example, when you walk on a heated floor, the heat of the floor is directly transmitted to your feet.

CONVECTION HEATING:

* A convector uses the movement and circulation of molecules to transmit heat.

* Radiators that operate through the convection process suck the air and then heat it with an electric heater.

* This air is then blown into the room to warm the surrounding air.

RADIANT HEATING:

* Radiation is a process that transmits heat by waves.

* Indeed, waves are emitted naturally by all objects.

* The hottest elements transmit their heat to the colder elements by these waves. We talk about radiation.

* A radiator that uses this principle generally heats a plate that will transmit heat into the ambient air through the radiation process.
