Question 1 of 4
What fundamental constraint prevents any physical system from achieving 100% energy efficiency?
Explanation: The second law of thermodynamics states that in any energy transfer, some energy is lost as waste heat, increasing the overall entropy (disorder) of the system and preventing 100% efficiency.
Question 2 of 4
How do catalysts accelerate chemical reactions without being consumed in the process?
Explanation: Catalysts provide an alternative reaction pathway with a lower activation energy, allowing the reaction to occur more rapidly at lower temperatures.
Question 3 of 4
What is the primary role of Adenosine Triphosphate (ATP) in cellular biology?
Explanation: ATP is the primary energy carrier in all living organisms, capturing chemical energy obtained from the breakdown of food molecules and releasing it to fuel cellular processes.
Question 4 of 4
According to Einstein's theory of general relativity, what is gravity?
Explanation: General relativity posits that mass and energy curve the fabric of spacetime, and this curvature dictates the motion of objects, which we perceive as the force of gravity.
