Explanation: 

Detailed explanation-1: -Lavas like those in Hawaii can reach temperatures a bit over 2, 000 degrees Fahrenheit. That’s hot enough to incinerate organic material, such as wood, says Liz Cottrell, a research geologist with the Global Volcanism Program at the National Museum of Natural History.

Detailed explanation-2: -Here are some temperatures recorded at different times and locations: The eruption temperature of Kīlauea lava is about 1, 170 degrees Celsius (2, 140 degrees Fahrenheit). The temperature of the lava in the tubes is about 1, 250 degrees Celsius (2, 200 degrees Fahrenheit).

Detailed explanation-3: -Magma is extremely hot-between 700° and 1, 300° Celsius (1, 292° and 2, 372° Fahrenheit). This heat makes magma a very fluid and dynamic substance, able to create new landforms and engage physical and chemical transformations in a variety of different environments.

Detailed explanation-4: -When a volcano erupts, the surroundings can get pretty warm. Basalt lava (the most common type) can reach temperatures of around 1200 degrees Celsius, while rocks scattered around the volcano can also reach temperatures of up to 1, 000 degrees Celsius.
