- So each four dot shows four different states for an ideal gas. P is the pressure and the other one is the density of the gas. Is temperature of state 1 less or greater than the state 2? Can you please explain why?Complete the following statement: The absolute temperature of an ideal gas is directly proportional to O the average momentum of a molecule of the gas. O the amount of heat required to raise the temperature of the gas by 1 Cº. O the number of molecules in the sample. O the relative increase in volume of the gas for a temperature increase of 1 Cº. O the average kinetic energy of the gas.Problem #1: An ideal gas of initial volume V=1m^3, initial temperature T=1000C and initial pressure P=10,000 Pa is heated up to a final temperature T=3000C and allowed to expand into a final volume V=3m^3. What is the final pressure?
- Suppose a tank contains 521 m³ of neon (Ne) at an absolute pressure of 1.01×105 Pa. The temperature is changed from 293.2 to 294.4 K. What is the increase in the internal energy of the neon?If a (non-ideal) gas has non-negligible attractive intermolecular forces, would you expect the temperature to increase, decrease, or stay the same during an iso-enthalpic expansion of the gas? Explain your reasoning.A good explanation would be really helpful
