The question is incomplete, the complete question is:
Which of these would best describe the outcome of increasing the kinetic energy of the molecules in the above picture? A) The temperature will increase. B) The temperature will decrease. C) The temperature will remain unchanged. D) The temperature would fluctuate up and down.
Answer:
The temperature will increase
Explanation:
Temperature is defined as the average kinetic energy of the molecules of a body. Increasing the kinetic energy of the molecules will also increase the temperature of the molecules.
Similarly, kinetic energy is proportional to temperature. Hence an increase in the kinetic energy of molecules also leads to increase in the temperature of the system.
Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.
