In summary, the problem involves finding the new pressure after adding heat to a helium atom until its rms speed has increased by 50%. The formula for rms speed is given, as well as the mass of a helium molecule. There is a question about whether the rms speed of a helium ...
1.Understand the formulas: - The formula for the root mean square speed (u_rms) of a gas is given by: urms=√3RTM whereRis the gas constant,Tis the temperature in Kelvin, andMis the molar mass (molecular weight) of the gas.
