Task id16325

The vessel contains m = 1.28 g of helium at a temperature t = 27° C. How many times (n) will the root-mean-square speed of helium molecules change if A = 252 J of work is performed during its adiabatic compression? The molar mass of helium is μ = 4 g/mol. Universal gas constant R = 8.3 J/mol K.
