Four students are carrying out different laboratory procedures.
Piroja is mixing baking soda and vinegar to see if it reacts.
Jason is heating salt water over a burner until the water evaporates.
Kali is putting crushed ice and ice cubes on a table to see which melts first.
Francisco is separating iron filings from sand using a magnet.
Which experiment relies on convection?
Piroja’s experiment
Jason’s experiment
Kali’s experiment
Francisco’s experiment

Jason’s experiment of  heating salt water over a burner until the water evaporates relies on convection.

Convection is single- or multiphase fluid flow that develops on its own as a result of the interaction between a fluid's body forces—most frequently gravity and density—and material property heterogeneity.

Convection caused by the effects of thermal expansion and buoyancy might be assumed when the cause of the convection is unknown. Convection may also occur in mixes or soft materials where particles can move.

Convective flow can be either transitory (as when an oil and water multiphase combination separates) or steady state. Convection may result from electromagnetic, gravitational, or fictitious body forces. The composition of the Earth's atmosphere, seas, and mantle is influenced by heat transfer through natural convection.

Hence, heating salt water over a burner until the water evaporates relies on convection.
