Question

recognizing forms of energy
match each form of energy with its correct description.
chemical
involving energy stored in chemical
bonds
thermal
involving electrical charges
electrical
involving the motion of atoms
mechanical
involving the position and motion of
an object

Explanation:

• Chemical energy is the energy stored in chemical bonds.
• Thermal energy is related to the motion of atoms (as temperature is a measure of the average kinetic energy of atoms/molecules).
• Electrical energy involves electrical charges (e.g., electrons moving in a circuit).
• Mechanical energy involves the position (potential energy) and motion (kinetic energy) of an object.

Answer:

• chemical: involving energy stored in chemical bonds
• thermal: involving the motion of atoms
• electrical: involving electrical charges
• mechanical: involving the position and motion of an object
