The cylinder contains argon weighing 5 kg at a temperature of 50g. Celsius. What is the internal energy of the gas?

m = 5 kg. T = 323 “K. M = 40 * 10 ^ -3 kg / mol. R = 8.31 J / K * mol. U -? The internal energy of a monatomic zag is determined by the formula: U = 3 * m * R * T / 2 * M. U = 3 * 5 kg * 8.31 J / K * mol * 323 “K / 2 * 40 * 10 ^ -3 kg / mol = 503,000 J.
Answer: the internal energy of argon is U = 503,000 J.
