QUIZ 6 Chapter 4 Name 1. Name three things that will not be possible without energy. 2. Calculate the energy that can be derived from a moving stone whose mass is 50 kg and its velocity is 100 m/s. 3. Radiant energy is the energy from the and 4. Write the type of energy being described below: a. The energy that is available while I am sleeping b. The gasoline that I put in my car combust to generate this energy c, Electrons move from anode to cathode to generate this energy. 5. Heat is the energy that flows from colder object to a hotter object. True/False. 6. Consider the reaction below: CO2 H20 Energy C6H12O 0, a. Balance this chemical equation. b. How many moles of CO2 are involved in this reaction? c. Is this reaction exothermic orExplanation / Answer
Energy can be in different forms, kinetic energy, potential energy, heat energy to name a few.
without heat energy, we can not cook food. Without electrial energy, we can not have hot water for bathing. With out mechanical energy, we can not drive the vehicle.
2. Moving mass posses kinetic energy which is = (1/2)*mV2 = (1/2)*50*100*100 =25000Joules
3. Radiant energy is the eneegy from electromagnetic waves and heat energy
4.During sleep, metabolic energy is used. During combustion, it is the heat energy getting converted to mechanical energy while driving. Electrical energy during moveent of electron from anode to cathode.
5. any thing from higher potential to lower potential. Heat energy also flows from higher to lower. Hence the given statment is false.
