Propane (C3H8) is a possible alternative automobile fuel with a density of 4.0 lb/gal and a standard enthalpy value Hº = -104.2 kJ/mol. Find its higher heating value (HHV) and net heat of combustion (LHV) in kJ/mol and in Btu/gal.

What amount of heat energy is required to heat 2.50 grams of water at 45°C (c = 4.18 J/g°C) to 85°C? er]

A food product containing 80% moisture content is being frozen. Estimate the specific heat of the product at -8 ° C when 82% of the water is frozen. The specific heat of the dry product is 2.5 kJ / (kg ° C). it is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and the specific heat of ice follows the function Cp es = 0.0062 Tbeku + 2.0649. Cp frozen product = AnswerkJ / kg ° C.

ll Verizon 99% 1:01 AM Done 3. A vessel containing 50 liters of saturated steam at 150 °C is cooled down to 25 °C. Using data from steam tables, determine the final mass and volume of the liquid water in the vessel. Calculate how much heat needs to be removed

A food product containing 80% moisture content is being frozen. Estimate the specific heat of the product at -6 ° C when 80% of the water is frozen. The specific heat of the dry product is 2 kJ / (kg ° C). It is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and that the specific heat of ice follows the function Cp es = 0.0062 T frozen + 2.0649. Cp frozen product =    kJ / kg ° C.
