$\bullet$$\bullet$ STP. The conditions of standard temperature and pressure(STP) are a temperature of $0.00^{\circ} \mathrm{C},$ and a pressure of 1.00 atm. (a) How many liters does 1.00 mol of any ideal gas occupy at STP? (b) For a scientist on Venus, an absolute pressure of 1 Venusian-atmosphere is 92 Earth-atmospheres. Of course she would use the Venusian atmosphere to define STP. Assuming she kept the same temperature, how many liters would 1 mole of ideal gas occupy on Venus?

a) 22.4$L$b) 0.244$L$

In physics, the second law of thermodynamics states that the total entropy of an isolated system can only increase over time. The total entropy of a system can never decrease, and the entropy of a system approaches a constant value as the temperature approaches zero.

03:25

The First Law of Thermodynamics is an expression of the principle of conservation of energy. The law states that the change in the internal energy of a closed system is equal to the amount of heat energy added to the system, minus the work done by the system on its surroundings. The total energy of a system can be subdivided and classified in various ways.

In the first part of this problem, we want to calculate the space occupied by 1 mole of any ordeal guess at standard temperature and pressure on earth on earth. The atmospheric pressure at s b is equal to 1 atmosphere, which is equal to 101325 pascal and at temperature is equal to 0.00 degree celsius, which is equal to 273.15 kelvin. So, by using the article gas equation we have v, i p v is equal to n t from here. By rearranging, for we get v is equal to n r t upon be. We have a number of moles equal to 1, multiply real gas constant. That is, 8.314472 joule per mole per kelvin and temperature is 273.15 kelvin upon pressure is 101325 pascal, so we get volume occupied by 1 mole of dal gas on earth equal to 22.4 litere. Now, in the second part of this problem, we want to calculate the volume occupied by 1 mole of gas on venus so again taking a deal. Gas equation we have p v, is equal to n t, so from here we get v is equal to energy. Upon again, here, n is equal to 1. More and r is 8.31472 joule per mole per kelvin, and the temperature is 273.15 kelvin upon pressure, and here pressure on venus that is equal to 1 venoceanatmospheric, which is equal to 92 times of the pressure unitamearth. That is 92 times of atmosphere which is equal to 92 multiply 101325 pascal. So we get the value of p equal to 92 multiply 101325, pascal. So by computing all these values we get v equal to 0.243 liter.
