Chapter 8, Problem 8.14P
Interpretation Introduction

(a)

Interpretation:

The average rate of heat loss should be calculated.

Concept introduction:

The amount of heat required to increase the temperature by one degree is defined as heat capacity.

The unit used to express it is thermal energy per degree temperature.

The total energy in the system due to temperature and pressure per unit of mass is known as specific enthalpy. Change in specific enthalpy is given as,

ΔH=HPHR

Where, HP = specific enthalpy of products and HR = specific enthalpy of reactants

Interpretation Introduction

(b)

Interpretation:

The total quantity of electricity that the heater must deliver should be calculated.

Concept introduction:

The amount of heat required to increase the temperature by one degree is defined as heat capacity.

The unit used to express it is thermal energy per degree temperature.

The total energy in the system due to temperature and pressure per unit of mass is known as specific enthalpy. Change in specific enthalpy is given as,

ΔH=HPHR

Where, HP = specific enthalpy of products and HR = specific enthalpy of reactants

Interpretation Introduction

(c)

Interpretation:

The cost of heating and total cost should be calculated.

Concept introduction:

The amount of heat required to increase the temperature by one degree is defined as heat capacity.

The unit used to express it is thermal energy per degree temperature.

The total energy in the system due to temperature and pressure per unit of mass is known as specific enthalpy. Change in specific enthalpy is given as,

ΔH=HPHR

Where, HP = specific enthalpy of products and HR = specific enthalpy of reactants

Interpretation Introduction

It's what makes food taste so good. Lipids or fats are relatively large molecules that pack a high-calorie wallop (over 9 kilocalories per gram, compared with about 4 kilocalories per gram for either carbohydrates or proteins). While that's great if your body's storing fat to make it through food shortage (imagine how much more you'd weigh if your body had to store an equivalent amount of energy in the form of carbohydrates!) it's not so great if you're consuming a half gallon of ice cream and trying to watch your weight at the same time. 11.1. List at least three types of lipids have you learned about. 11.2. What is a primary characteristic of all lipids? 11.3. Based on this characteristic, would you predict they are hydrophilic or hydrophobic? Hint: Think about what happens when you put a greasy pan into a sink of water without detergent. 11.4. Whať's the key difference between a saturated fat and an unsaturated fat (see figure 3.15 & 3.15 for help)?
A sample of 25.2 g of a candy bar was burned in a calorimeter. The calorimeter was calibrated to have a heat capacity of 8.72 kcal/ °C. The heat released caused the temperature of the calorimeter to increase 16.7 °C. Calculate the food caloric content of the candy bar in nutritional calories per gram to three significant figures. Recall that 1 nutritional calorie (Cal) = 1 kcal.
