This model is supposed to students understand how a volcano works. with that purpose of mind, what is the limitation of this

The limitation of this model is that it does not accurately demonstrate the degree of dangerousness of the volcanoes.

Explanation:

The volcano is the natural phenomenon responsible for the release of magmatic material, ashes and gases from the Earth's interior to the surface. The eruption of a volcano has destructive consequences, especially in populated places. Among the losses are pollution of soil, water and air, destruction of vegetation and homes, in addition to deaths.

Although a volcano model demonstrates the shape and functioning of the volcano, these models do not accurately represent the danger that an active volcano represents as lava and all the smoke generated by volcanoes.

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
