1.0 joule = 0.239 cal
5350 joule = 5350 x 0.239 = 1.279 x 103 cal
so answer = option c = 1.279 x 103 cal
Add Answer to:
For a process at constant pressure, 5350 joules are released. This quantity is equivalent to 2.238...

Assuming constant pressure, rank these reactions from most energy released by the system to most energy absorbed by the system, based on the following descriptions: Surroundings get colder and the system decreases in volume. Surroundings get hotter and the system expands in volume. Surroundings get hotter and the system decreases in volume. Surroundings get hotter and the system does not change in volume. Also assume that the magnitude of the volume and temperature changes are similar among the reactions. Rank...

4. An ideal gas with constant specific heats undergoes a process from an initial pressure of 50 kPa and initial specific volume of 4 m^3/kg to a final pressure of 80 kPa and final specific volume of 5 m^3/kg. The mass of the carbon monoxide is 3 kg. The gas has a molar mass of 44 kg/kmol and a specific heat at constant volume of 0.98 kJ/(kg∙K). Determine the entropy change of the gas during the process in kJ/K.
