All these statements about energy and energy conversion are true, except

  1. thermal energy may be defined as light energy

  • chemical to thermal energy conversion occurs when gasoline burns
  • mechanical energy' is defined as the ability to do work
  • mechanical to electrical energy conversion occurs when the engine drives the generator
  • To determine

    The incorrect statement about energy and its conversion.

    Explanation

    Given information:

    All these statements about energy and energy conversion are true, except ____.

    a. Thermal energy may be defined as light energy

    b. Chemical to thermal energy conversion occurs when gasoline burns.

    c. Mechanical energy is defined as the ability to do work.

    d. Mechanical to electrical energy conversion occurs when the engine drives the generator.

    Statement (a) is incorrect as thermal energy is higher grade energy when compared to light energy. Light energy cannot be used in generation of thermal power.

    When gasoline burns chemical reactions takes place inside the combustion chamber which gives rise to thermal energy...
