EGEE 102 FINAL Lesson 1 Which one of the following is a type of fuel formed from the remains of plants or sea creatures millions of years ago C Fossil fuel Fossil fuels are formed from plant and animal remains that were fossilzed millions of years ago Joule is a unit of power B FALSE Joule is a unit of energy used by scientists and engineers One calorie is defined as the amount of energy that is required to raise the temperature of B 1 g of water by 1 C A calorie is the amount of energy required to heat one gram of water through 1 C What is the form of energy in fossil fuels D Chemical Energy in fossil fuels is stored in the bonds as chemical energy Energy can be converted from one form to another A TRUE Energy can neither be created nor be destroyed but it can be converted from one form to another Energy and work have the same units A TRUE Energy is something that has ability to move things or do work Wind energy can be converted to electricity A TRUE Renewable and non renewable energy sources can be converted to electricity and heat Which natural resource is the United States richest in C Coal We have almost 25 of world s coal reserves Food calorie Cal is a unit of A Energy A food calorie cal is equal to one kilocalorie The food calorie is often used when measuring the energy content of food From the following identify the group where all energy sources are renewable energy sources D Solar Nuclear Fusion Solar Nuclear Fusion Biomass Wind Tidal are renewable energy sources Nuclear Fission Petroleum Coal are non renewable energy sources One BTU of energy is enough to do what B Heat one pound of water by one degree Fahrenheit A BTU is the amount of energy that is required to heat 1 lb of water by 1 F Energy in Uranium is stored as energy A Nuclear Uranium is a radio active material Energy in Uranium is stored as nuclear energy A Calorie is a unit of energy A TRUE 1 calorie is the amount of energy needed to raise the temperature of one gram of water by one degree Celsius A BTU has more energy than a calorie A TRUE A BTU is the amount of heat required to heat 1 lb 454 grams of water through 1 F Whereas 1 calorie is the amount of heat required to raise 1 g of water through 1 C Therefore there is more energy in one BTU From a computer the useful energy output is in the form of energy C Radiant The useful energy output from a computer is in the form of radiant energy BTU is a unit of energy A TRUE BTU is a unit of energy equal to the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit Energy in wood renewable is stored as D Chemical Energy in wood is stored in the form of chemical energy From the following identify the list where all energy sources are non renewable energy sources C Nuclear Fission Petroleum Solar Nuclear Fusion Biomass Wind Tidal Solar are renewable energy sources Nuclear Fission Petroleum Coal Natural Gas are non renewable energy sources Therm is a unit that is generally used to measure the energy contained in natural gas A TRUE Therm is unit of energy It is used to describe the energy contained in natural gas One therm equals 100 000 Btu The energy in fossil fuels such as petroleum is stored as energy C Chemical In fossil fuels energy is stored in bond as chemical energy Joule s is a unit of A Power Joule is unit of energy used by scientists and engineers J s is the rate at which energy is used If Peter expends 1 000 calories running a mile in one hour and Samantha burns 1000 calories riding a bike in forty five minutes Which one of the two exerted more power B Samantha Power Energy Time Peter Power 1000 1 1000 cal hr Samantha Power 1000 0 75 1333 33 cal hr In which one of the following lists are all energy sources examples of mechanical energy D Wind Tidal energy Coiled spring Wind Tidal energy Coiled spring Flowing water High pressure steam are examples of mechanical energy Sun is an example of nuclear energy Biomass Fuel oil Wood are examples of Chemical Energy From the following pick the set of units that contains all power or energy units B FALSE A kW MW BTU s J s kW MW BTU s J s Cal hr are units of Power kWh BTU J Cal are units of Energy Geothermal heat can be used to produce electricity A TRUE Renewable and non renewable energy sources can be converted to electricity and heat Megawatt is a unit of energy One watt equals the production or use of one joule of energy per second 1 J s An energy source is nonrenewable if An energy source is non renewable if the source cannot be regenerated in a reasonable time period eg fossil fuels Units of energy when divided by time of usage give units of Power Energy Time One British Thermal Unit BTU is defined as the amount of energy required to raise the temperature of One British Thermal Unit BTU is defined as the amount of energy required to raise the temperature of 1 lb of water through 1 F C if the source cannot be regenerated in a reasonable time period C 1 lb of water through 1 F A Power B FALSE C Chemical B They are the same What is the form of energy in biomass Energy is stored in biomass in the form of chemical energy kWh is a unit of power kWh is the amount of energy from the steady production or consumption of one kilowatt of power for a period of one hour If Peter expends 2 000 calories running a mile in one hour and Samantha burns 1000 calories riding a bike in thirty minutes Who exerted the greatest amount of power Power Energy Time Peter Power exerted 2000 1 2000 cal hr Samantha Power exerted 1000 0 5 2000 cal hr Which one of the following is an odd set of units J s Watt BTU s are units of Power kWh MWh BTU J Cal Joule are units of Energy One calorie is defined as the amount of energy that is required to raise the temperature of calorie is a unit of energy 1 calorie is the amount of energy required to raise the temperature of 1 g of water through 1 C Photosynthesis is a process by which energy is converted to energy B 1 g of water through 1 C B J s Watt BTU s kW h A Solar to Chemical energy A TRUE B FALSE Plants convert solar energy into chemical energy by a process called photosynthesis Nuclear fusion is a renewable source of energy Nuclear fusion uses hydrogen isotopes and hydrogen isotopes can …
