Question
Chapter 9, Problem 12E
Interpretation Introduction
Interpretation:
The difference between energy and power is to be explained.
Concept introduction:
Power is defined as the energy used per unit time to do some work. SI unit of power is watt (W) which is joule/second.
The power that arises by utilizing the chemical or physical resources for providing heat and light or carrying out various processes is known as energy. The SI unit of energy is joule.
The law of conservation of energy states that energy can neither be created nor be destroyed, it can be converted to other forms.

For similar light intensity, compact fluorescent bulbs use about 25% of the energy of incandescent bulbs. Let's say you replaced a bulb of 100W with a fluorescent bulb and that your utility charges $0.15/kW-hour. How many dollars would you save in electricity in the 10,000-hr. lifetime of the bulb?
A typical candy bar weighs about 2 oz (1.00 oz = 28.4 g).(a) Assuming that a candy bar is 100% sugar and that 1.0 g of sugar is equivalent to about 4.0 Calories of energy, calculate the energy (in kJ) contained in a typical candy bar.(b) Assuming that your mass is 58 kg and you convert chemical potential energy to work with 100% efficiency, how high would you have to climb to work off the energy in a candy bar? (Potential energy = mass × g × height, where g = 9.8 m/s2.)(c) Why is your actual conversion of potential energy to work less than 100% efficient?
The density of an unknown substance is 3.08 g/ mL. If the volume is 4.56 what is the mass of this sample show work?
