Detailed explanation-1: -It takes temperatures between 600 and 1, 300 degrees Celsius (1, 100 and 2, 400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
Detailed explanation-2: -The short answer is that while lava is hot, it’s not hot enough to melt the rocks on the side of or surrounding the volcano. Most rocks have melting points higher than 700℃. Lava is between 700℃ and 1200℃ when it erupts but starts to cool as it slides down the side of the volcano.
Detailed explanation-3: -Lava can melt any material, including rubber, tanks, cars, trees, and grasses, with melting points below 2, 190° F. However, if it cannot completely melt these materials, it can set them on fire and ultimately turn them to ashes.
Detailed explanation-4: -Steel often melts at around 1370 degrees Celcius or 2500°F. Most lava is between 700 to 1200 degrees Celsius, so most lava won’t melt steel.
Detailed explanation-5: -We conclude that the optimal heat generated by lava at 2, 190°F cannot melt the tungsten because of its high melting point. Other examples of metals and ceramics that can withstand lava’s temperature include; titanium, iridium, iron alloys, osmium, nickel alloys, aluminum oxide, mullite, and silicon nitride.
