The cylinder contains argon at a temperature of 25 degrees Celsius. The gas concentration is 2 * 10 ^ 25 m ^ -3. What is the pressure in the cylinder?
To calculate the argon pressure value in the indicated cylinder, we use the formula: P = n * k * T.
Constants and variables: n – concentration of argon molecules (n = 2 * 10 ^ 25 m-3); k (Boltzmann’s constant) = 1.38 * 10 ^ -23 J / K; T is the absolute temperature of argon (T = 298 K (25 ºС)).
Let’s perform the calculation: P = n * k * T = 2 * 10 ^ 25 * 1.38 * 10 ^ -23 * 298 = 82 248 Pa.
Answer: Argon is in the indicated cylinder under a pressure of 82,248 Pa.
