Translational energy of molecules is a part of ____________energy of the system.

Calculate the temperature at which the average translational kinetic energy of the molecules of a gas will be 1/3 rd of that at 180^@C ?

Statement I: The root mean square speeds of the molecules of different ideal gases at the same temperature are the same. Statement II: The average translational kinetic energy of molecules of different ideal gas are same at the same temperature.

Find out the temperature at which the average translational kinetic energy of a gas molecule will be equal to the energy gained by an electron on acceleration across a potential difference of 5V, Boltzmann constant, k=1.38 times 2.^-23 J.K^-1 1 ev=1.6 times 10^-19 J .

Statement I: The total translational kinetic energy of all the molecules of a given mass of an ideal gas is 1.5 times the product of its pressure and its volume. Statement II: The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.

At 27^(@)C , average translational kinetic energies of the molecules in 8g of CH_(4),8g of O_(2) and 8g of He are overline(in_(1)),overline(in_(2)) and overline(in_(3)) respectively and total kinetic energies of the molecules in these gases are E_(1),E_(2) and E_(3) respectively. which of the following is true-

Statement I: The total translation kinetic energy of all the molecules of a given mass of an ideal gas is 1.5 times the product of its pressure and its volume. Statement II: The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.

The internal energy of a system is U_(1) . In a process, work done by the system is W and heat accepted by the system is Q. At the end of the process, the internal energy of the system is

If the average kinetic energy of the molecules of a certain mass of a gas decreases, then

Change in internal energy of a system is
