Consider the following statements:1.Real gases act more like ideal gases as the temperature increases.2.When n and T are constant,a decrease in P results in a decrease in V.3.At 1 atm and 273 K,every molecule in a sample of a gas has the same speed.4.At constant T,CO₂ molecules at 1 atm and H₂ molecules at 5 atm have the same average kinetic energy.
Which of these statements is true?

Question

Quizplus · Accepted Answer

1. Real gases actually deviate from ideal behavior at low temperatures and high pressures. 
2. This statement is true as it follows Boyle's Law. 
3. At a given temperature, the average speed of gas molecules is the same. However, the distribution of speeds follows a Maxwell-Boltzmann distribution, so some molecules will be moving faster than others. 
4. The average kinetic energy of gas molecules depends only on temperature, not pressure or the number of molecules present. Therefore, this statement is true.
