The heat capacity of sulfuric acid has the units J/(g mol) and is gr the relation Heat capacity = 139.1 +1.56* 10-¹ T where T is expressed in °C. Modify the formula so that the resulting expression has the associate units of Btu/h mol) (R) and Tis in °R

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]

Number 1A food product containing 82% 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 that the specific heat of ice follows the function Cp es = 0.0062 Tbeku + 2.0649. identify :a. Cp frozen product = Answer in kJ/kg°C

Q.3 Two formulas for the heat capacity of CO are given here: C,(cal/(mol-"C)] = 6.890 + 0.0014367(°C) C,(Btu/(lb-mole "F)] = 6.864 + 0.00079787('F) Starting with the first formula, derive the second. (Recall Section 2.5, and remember that the tem- perature unit in the denominator of C, refers to a temperature interval.)
