Question

What does the first law of thermodynamics tell us about the energy of the universe?

A. Energy is conserved
B. Energy is created
C. Energy is destroyed
D. Energy is constant

Answer 1

The first law of thermodynamics states that energy in the universe is constant and conserved, and cannot be created or destroyed, only transferred or transformed.The correct answer is option A.

Step-by-step explanation:

The first law of thermodynamics, also known as the law of conservation of energy, tells us about the energy of the universe by stating that the total amount of energy is constant.

This means that energy cannot be created or destroyed in the universe, but only transferred or transformed among various forms.

For instance, light bulbs convert electrical energy into light and heat energy, gas stoves turn chemical energy from natural gas into heat energy, and plants transform the energy of sunlight into chemical energy stored within organic molecules during the process of photosynthesis.The correct answer is option A.
