Question

Which of the following quantities is the same for all ideal gases at the same temperature?
(a) The kinetic energy of 1 mole
(b) The kinetic energy of 1 g
(c) The number of molecules in 1 mole
(d) The number of molecules in 1 g

Answer 1

Explanation:

option B is the right answer......... ..

Answer 2

For all ideal gases at the same temperature,  The kinetic energy of 1 mole and  The number of molecules in 1 mole are same

Explanation:

• The kinetic energy is directly proportional to T per mole of an ideal gas. Therefore, all ideal gases will be the same.  
• Number of molecules in 1 mole of an ideal is the same for all ideal gases, since ideal gases obey the law of Avogadro.
• Therefore, the answers are option A ( one Mole's Kinetic Energy )  and option B ( The molecules count in one mole)  both are correct.
