Buy here: The Mask of the Red Death 3D face mask

Now there are three masses to use. The first is the official one, which is a bullsh** weight. 10 tons for a The Mask of the Red Death 3D face mask 122 meter long, 30 meter tall dragon is kinda bullsh**. Then there’s a weight I guesstimated, which is 10k tons, which is reasonable. Then there’s the weight from the screenshot, which is 63,789 tons.

For c, I guess I’ll just use the specific heat capacity of water bc it’s the quickest thing I can find, and bc life forms are made of water.

For ΔT, there are two ends. Toothless’s blasts have been stated to be Oxyacetylene, which, according to the wiki for HTTYD, is 3,300℃. And another end which states his blasts are plasma, which is at least 6,000 K in temperature. This is 5,727℃.
