A spacecraft is fueled using hydrazine (N2H4; molecular weight of 32 grams per mole [g/mol]) and carries 1 comma 630 kilograms [kg] of fuel. On a mission to orbit a planet, the fuel will first be warmed from negative 199 degrees Fahrenheit [°F] to 100 degrees Fahrenheit [°F] before being used after the long space flight to reach the planet. The specific heat capacity of hydrazine is 0.099 kilojoules per mole kelvin [kJ/(mol K)]. If there is 250 watts [W] of power available to heat the fuel, how long will the heating process take in units of hours [h]?
