Which of the following statements about energy is true?
A
Energy is the capacity to do work or produce heat.
B
Potential energy is always greater than kinetic energy in all systems.
C
Energy can be created and destroyed in chemical reactions.
D
Energy cannot be transferred between objects.
Verified step by step guidance1
Understand the definition of energy in the context of chemistry: Energy is the capacity to do work or produce heat. This is a fundamental concept in thermodynamics and chemistry.
Evaluate the statement 'Potential energy is always greater than kinetic energy in all systems.' Consider that potential and kinetic energy can vary depending on the system and conditions; one is not always greater than the other.
Analyze the statement 'Energy can be created and destroyed in chemical reactions.' Recall the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another.
Consider the statement 'Energy cannot be transferred between objects.' Remember that energy transfer is common, such as heat transfer or work done between objects.
Conclude that the true statement is the one defining energy as the capacity to do work or produce heat, since the other statements contradict fundamental principles of energy conservation and transfer.
