I believe that the subject is supposed to be science
Conversating and conversate are actual words
Answer: Option (D) is the correct answer.
Explanation:
According to Kinetic theory of gases, molecules of a gas move in rapid and random motion. That is, particles are constantly in linear motion.
When these molecules colloid with each other then no energy is gained or lost by them. Also, these molecules occupy negligible amount of volume as compared to the volume of the container in which they are placed.
Moreover, as there is no energy loss taking place so, these molecules of gas undergo perfect elastic motion.
Therefore, we can conclude that all of the above given options are true according to the kinetic theory of gases.
At 37°C, the pH of distilled water is actually around 6.8, which means the human extracellular fluid is quite alkaline. However, the intracellular pH of the warm-blooded human is still around 6.8. This has been confirmed by various destructive and non-destructive measurements.
