Comment on the following statement: the temperature of all the molecules in a sample of a gas is the same.

Comment on the statement - Telophase is reverse of prophase.

Give negation of the following statement: All Mathematician are man.

Statement-1: The de-Broglie wavelength of a molecules (in a sample of ideal gas ) varies inversely as the square root of absolute temperature Statement 2:The rms velocity of a molecules (in a sample of ideal gas ) depend in temperature.

Is the temperature of an isolated system of gas be changed ?

Statement-1: The total translational kinetic energy of fall the molecules of a given mass of an ideal gas is 1.5 times the product of its pressure and its volume because. Statement-2: The molecules of a gas collide with each other and the velocities of the molecules change due to the collision.
