(a)
Interpretation:
Some of the energy losses that take place when driving a car has to be listed out.
Concept Introduction:
Heat of combustion: It is also known as potential heat of fuel. Heat of combustion of carbon depends on its allotropic form.
A fuel is a substance which releases energy in the form of heat while undergoing combustion. Hydrocarbons which have high heats of combustion make it a best fuel.
Combustion reaction: It is the reaction in which hydrocarbons are heated in presence of oxygen results to give water and carbon dioxide with heat.
(b)
Interpretation:
Given the assumption that only 15% of the energy from fuel combustion is used to move the vehicle. The percent used to move the passengers has to be estimated.

Chemistry In Context
- What if energy was not conserved? How would this affect our lives?arrow_forwardA piece of chocolate cake contains about 400 calories. A nutritional calorie is equal to 1000 calories (thermochemical calories), which is equal to 4.184 kJ. How many 8-in-high steps must a 180-lb man climb to expend the 400 Cal from the piece of cake? See Exercise 28 for the formula for potential energy.arrow_forwardAnalyze transfer of energy from one form to another in each situation. In a Space Shuttle, hydrogen and oxygen combine to form water, boosting the shuttle into orbit above Earth. You eat a package of Fritos, go to class and listen to a lecture, walk back to your dorm, and climb the stairs to the fourth floor.arrow_forward
