How hot is the lava? Lava and Melon Experiment at Iceland Volcano. 20.05.21

Lava and melon. Experiment at Fagradalsfjall Volcano, Reykjanes peninsula, Iceland. May 20, 2021. When lava first breaks through Earth's surface, it is an extremely hot liquid. On average, fresh lava can be between 700° and 1,200° Celcius / 1,300° F and 2,200° F The temperature of the lava in the tubes is about 1,250 degrees Celsius (2,200 degrees Fahrenheit). Lava doesn't have a fixed temperature, varying from approximately 650 to 1600 degrees Celsius (1300 to 2900 degrees Fahrenheit). Viscous lava typically runs between 700 and 900 degrees C. When the entire flow cools below about 1000 degrees Celsius (1800 degrees Fahrenheit), it has solidified, but the interior is still very hot. Solidification of lava flows ranging 20–30 m (65–100 ft) thick could take about 2.5–6 years. The thickest flows on land, which are approximately 55 m (180 ft) thick, may take roughly 20 years to reach a completely solid state. Based on studies of lava flow cooling rates, it will takes more than 130 days for a flow 4.5 m, or 15 ft thick to cool to a temperature of about 200 degrees Celsius (290 degrees Fahrenheit). Lava cools very quickly at first forming a thin crust that insulates the interior of the lava flow. As a result, basaltic lava flows can form crusts that are thick enough to walk on in 10-15 minutes but the flow itself can take several months to cool. Since lava is a poor conductor of heat it cools slowly under neither the outside crust. Also the insulating properties of lava causes it to cool slower and slower over time. Thick stacks of lava flows (30 m or 100 ft thick) can take years to cool completely.

At the spot where I threw a melon there arrived a multimeter layers of lava in the following months, so I dont think anything remains of a melon:)
