- Suppose a tank contains 523 m³ of neon (Ne) at an absolute pressure of 1.01×105 Pa. The temperature is changed from 293.2 to 295.4 K. What is the increase in the internal energy of the neon?Suppose you have helium atoms in a sealed container and 20% of the atoms have a speed of 2.1 × 102 m/s and 80% have speed of 4.2 × 102 m/s. The atoms then collide with one another until the Maxwell-Boltzmann distribution is established. What is the temperature of the gas at equilibrium? Assume there is no heat exchange between the gas and the environment.The escape speed from the Moon is much smaller than from Earth and is only 2.38 km/s.

The specific heat capacity of the lemonade is virtually the same as that of water, c = 4186 J/kg 0C. After the ice and lemonade reached the equilibrium temperature, some ice still remains. The latent heat of fusion for water is Lf = 3.35 x105 J/kg. Assume that the mass of the cup is so small that it absorbs a negligible amount of heat, and ignore any heat lost to the surroundings. Determine the mass of ice that has melted.
