Neon gas is generally used in the sign boards. If it emits strongly at 619nm, calculate number of quantum present if it produces 2J of energy.

Neon gas is generally used in the sign boards. If it emits strongly at 616nm, calculate The frequency of emission

Neon gas is generally used in the sign boards. If it emits strongly at 617nm, calculate Distance travelled by his radiation in 30s

Lifetimes of the molecules in the excited states are often measured by using pulsed radiation source of duration nearly in the nano second range. If the radiation source has the duration of 2 ns and the number of photons emitted during the pulse source is 2.5 xx 10^15 , calculate the energy of the source.

104 kj of work is done on certain volume of a gas. If the gas releases 125 kj of heat, calculate the change in internal energy (in kj) of the gas.

Stages in generation of electrical energy from natural gas.

A gas mixture consists of 2.0 moles of oxygen and 4.0 moles of neon at temperature T. Neglecting all vibrational modes, calculate the total internal energy of the system.(Oxygen has two rotational modes.)

Nitrogen laser produces a radiation at a wavelength of 337.1 nm. If the number of photons emitted is 5.6 xx 10^24 , Calculate the power of this laser.
