Which statement about energy transformations is not true?
a all forms of energy can be transformed into thermal
b energy is never destroyed or created during transformations
c potential chemical energy always transforms into kinetic
d some thermal energy is always released during a transformation

C

Explanation:

Let's consider the conservation of energy

Energy can not be destroyed or created energy can be transferred one form energy to a another form of energy.

(A) Then all form of energy can be transfer into any form of energy . There for all forms of energy can be transformed to thermal energy

(B) This is the law of conservation of energy

(C)Potential chemical energy can be transferred into any form of energy. It's not only to kinetic energy

(D) Some amount of thermal energy always released when it's transferred energy due to reaction forces or frictional forces.
