Answer to Question #83421 in Physics for Naima

Question

1. At what temperature the root mean square velocity will be half of that standard pressure
and temperature, the pressure being kept constant.
2. For an ideal gas γ=1.4, calculate the values of molar specific heats of the gas. (R=8.31
J/Kmol)
3. How much heat is required to raise the temperature by 40 of 14g nitrogen gas at constant
pressure?[Molar mass of nitrogen=28 g, R=8.31J/Kmol for diatomic gas =5/2R]

screen from the plane of the slit is .73m. What is the distance from the central bright
point to the first bright point in the screen? [λ=550×10 -10 m]
5. The phase difference between two points in a wave is /2. What is the path difference
between those two points?
