(a)
Interpretation: The amount of energy in calories that can be transformed from the combustion of one peanut to be calculated.
Concept Introduction:
(a)

Answer to Problem SII2RE
Amount of energy that can be transformed from the combustion of one peanut is 1000cal.
Explanation of Solution
Given mass of water (m) = 100g
Temperature change
Specific heat of water is
The equation of heat is as follows:
Here H is heat, m is mass, C is specific heat and T is temperature.
Put the values in above equation is as follows:
Thus, amount of energy that can be transformed from the combustion of one peanut is 1000cal.
(b)
Interpretation: The amount of calories per gram of peanut to be calculated.
Concept Introduction: Thermodynamics is the analysis of heat transfer. Heat transfer direction is always from a hotter substance to colder one.
(b)

Answer to Problem SII2RE
The amount of calories per gram of peanut is
Explanation of Solution
Given initial mass of peanut = 3.75g
Final mass of peanut = 1.2 g
Thus
Thus the amount of calories per gram of peanut is
(c)
Interpretation: The amount of food calories in the bag to be calculated.
Concept Introduction: Thermodynamics is the analysis of heat transfer. Heat transfer direction is always from a hotter substance to colder one.
(c)

Answer to Problem SII2RE
Amount of food calories in the bag is 196078 cal.
Explanation of Solution
Given mass of peanut (M) =500 g
Thus, amount of food calories in the bag is 196078 cal.
