To calculate the difference between the two principal specific heat capacities for hydrogen, we can use the relationship between the specific heat capacities and the ideal gas law. The specific heat capacities at constant pressure (Cp) and constant volume (Cv) are related by the equation: \[ C_p - C_v = R \] Where \( R \) is the specific gas constant for hydrogen. ### Step-by-Step Solution: ...
