Question

Which is an example of radiant energy?

a. The sun heats a glass of water.
b. Water flows over a cliff.
c. Water falls from the sky as precipitation.

Which is an example of kinetic energy?
a. A rock sits at the top of a steep cliff.
b. The rock falls off of the cliff.

Which Law of Thermodynamics states that as energy is transferred, there is a significant amount lost as heat?
a. First Law
b. Second Law
c. Third Law

Answer 1

Radiant energy is best exemplified when the sun heats a glass of water, while kinetic energy is shown when a rock falls off a cliff. The Second Law of Thermodynamics states that energy transfer will result in energy loss as heat.

Step-by-step explanation:

An example of radiant energy is a. The sun heats a glass of water. This is because radiant energy includes energy in the form of light, such as sunlight, which can cause water to warm. An example of kinetic energy is b. The rock falls off of the cliff. As the rock falls, it is moving, and any object in motion has kinetic energy.The Second Law of Thermodynamics states that as energy is transferred, there is a significant amount lost as heat. This law reflects the phenomenon that energy transformations are not 100% efficient, and some of the energy will always be lost typically as heat.
