Making this for reasons.
In this cutscene, Cerberus freezes the entrance.
- Dante's height = 60 px = 1.8 meters
- h = 134 px = 4.02 meters (we will need that later)
- a = 370/2 = 185 px = 5.55 meters
Now onto the second picture:
- a = 5.55 meters = 342 px
- b = 297 px = ~6.39 meters
- Ellipse's surface area = pi * 5.55 * 6.39 = 111.4150127 meters^2
- Volume = 111.4150127 * 4.02 = 447.8883511 meters^3
- Ice density (frozen nitrogen) = 1026.5 kg/m^3
- Ice mass = 447.8883511 * 1026.5 = 459757.3924 kg
- Nitrogen's specific heat capacity = 1040 j/kg
- Nitrogen's freezing point = -210 C
- Melting point of nitrogen = -196 C
- Surroundings' temperature = 0 C (there's ice around, so I think this is a fair assumption)
- Q1 = 459757.3924 * 1040 * (-196-(-210)) = 6.69406763×10^9 J
- Fusion energy = 459757.3924 * 25000 = 1.14939348×10^10 J (source for latent heat of nitrogen)
- Q2 = 459757.3924 * 1040 * (0-(-196)) = 9.37169469×10^10 J
- Vaporization energy = 459757.3924 * 199000 = 9.14917211×10^10 J
- Q = Q1 + Fusion energy + Q2 + Vaporization energy = 2.0339667×10^11 J (48.61 tons of TNT, City Block level)
