Final answer:
The internal energy change of hydrogen can be determined using the empirical specific heat equation as a function of temperature.
Step-by-step explanation:
The internal energy change (ΔU) of hydrogen can be determined using the empirical specific heat equation as a function of temperature. The specific heat equation states that the change in internal energy (ΔU) is equal to the mass (m) of the substance multiplied by the specific heat capacity (c) of the substance, and then multiplied by the change in temperature (ΔT). Mathematically, this can be written as:
ΔU = mcΔT
Given the internal energy change (ΔU) of hydrogen in kJ/kg and the specific heat capacity of hydrogen as a function of temperature, you can calculate the mass (μ) of hydrogen, and then use it to calculate the specific heat capacity of hydrogen using the equation mentioned above. Finally, multiply the specific heat capacity of hydrogen by the change in temperature to find the internal energy change of hydrogen in kJ/kg.
