Final answer:
The energy in joules of 1 mol of gas at 100 degrees Celsius requires the specific heat capacity or type of gas to be calculated accurately. Option 1 with 8.314 J/mol is the ideal gas constant, which is part of the ideal gas law used to relate pressure, volume, and temperature of an ideal gas. Without additional context, none of the options directly provide the energy content at 100°C.
Step-by-step explanation:
The energy content of 1 mol of gas at 100 degrees Celsius cannot be accurately specified without additional information regarding the specific heat capacity or type of gas. However, in the context of the options provided, which seems to have some relation to constants related to gases, Option 1: 8.314 J/mol is representative of the ideal gas constant in Joules per mole per Kelvin (J/mol·K), which is used in the ideal gas law (PV=nRT). The energy in joules can be calculated using specific formulas pertaining to the characteristics of the gas (e.g., calculating internal energy, enthalpy).
The volume of 1 mol of an ideal gas is 22.41 Liters at 0°C and 1 atm which is known as standard temperature and pressure (STP), and can be used to determine the molar volume of gases at different conditions using the ideal gas law. The heat capacity would be required to find the internal energy or specific heat content at 100°C for a mole of gas. The values given in the options do not directly represent the energy in joules of a gas at a specific temperature without further context such as type of gas or specific heat capacity.
