Question

Which among the following energy transformation takes place when an automobile moves?

• A. $Electricalenergy\to Lightenergy\to Mechanicalenergy$
• B. $Electricalenergy\to Heatenergy\to Mechanicalenergy$
• C. $Chemicalenergy\to Heatenergy\to Mechanicalenergy$
• D. $Heatenergy\to Chemicalenergy\to Mechanicalenergy$

Answer 1

The correct option is C

$Chemicalenergy\to Heatenergy\to Mechanicalenergy$

An automobile requires burning of the fuel to move. The chemical energy stored in the fuel is converted to heat energy when the fuel starts to burn inside the engine of an automobile. This heat energy is further used to provide movement to the parts of an automobile to move forward or backwards (mechanical energy). Hence, the chemical energy of the fuel is converted to heat energy and further to mechanical energy.
