P2) (50 pts.) The boiling temperature of nitrogen at atmospheric pressure at sea level (1 atm pressure) is -196°C. Therefore, nitrogen is commonly used in low-temperature scientific studies, since the temperature of liquid nitrogen in a tank open to the atmosphere will remain constant at -196°C until it is depleted. Any heat transfer to the tank will result in the evaporation of some liquid nitrogen, which has a heat of vaporization of 198 kJ/kg and a density of 810 kg/m3...

Entropy of naphthalene: Consider naphthalene C10H8 at atmospheric pressure. It is a solid with a melting point at 80.1 degrees Celsius and a boiling point at 218 degrees Celsius. The latent heat of fusion is 19,123 kJ / mol. The molar heat at constant pressure of solid naphthalene has a functional temperature dependence (in K) which is linear. Its value is 0 at T = 0 K and 188.41 J / mol-K at T = 317.15 K. The molar heat...

answer asap please
A sealed balloon is filled with air at atmospheric pressure (P = 1.01 X 105 Pa) at 30°C (typical conditions for the surface of the Earth in St. Thomas). You take the (sealed) balloon with you on top of Mountain Top, which has an elevation of about 450m, where the average air pressure is 9.6 x 109 Pa. The temperature at the top is 26°C, a bit cooler. 2.5 pts. - a) How big is the balloon...
