Question

Какова внутренняя энергия 10 моль одноатомного газа при температуре 27°С

Answer 1

U=3*v*R*T/2=3*10*8,31*300/2=4986 Дж

Answer 2

Calculating Internal Energy of a Monoatomic Gas at 27°C

To calculate the internal energy of a monoatomic gas at 27°C, we can use the formula:

U = (3/2) * nRT

Where: - U = internal energy - n = number of moles - R = gas constant - T = temperature in Kelvin

First, let's convert the given temperature of 27°C to Kelvin: T(K) = 27°C + 273.15

T(K) = 300.15 K

Now, we can calculate the internal energy using the given values: U = (3/2) * nRT U = (3/2) * 10 * R * 300.15

Let's find the value of the gas constant R from the search results.
