Which term is Energy?

• A. Pressure
• B. Time
• C. Energy
• D. Temperature

Answer: (C)

This question tests recognizing energy as the quantity that represents the ability to do work. Energy, in physics, is a scalar quantity that can take many forms—kinetic, potential, thermal, chemical, electrical—and it’s what enables systems to cause changes or move objects. Among the options, only energy matches that meaning. Pressure describes force per unit area, not the capacity to do work. Time measures duration, not a quantity of ability to cause change. Temperature indicates how hot or cold something is, reflecting particle motion but not itself the stored or transferable ability to do work. So the term that best describes this concept is energy.
