Based on the formula for kinetic energy, how will the temperature change if you increase the average velocity of the molecules i
ICE Princess25 [194]

Answer:

Temperature will increase

Explanation:

As we know

KE = \frac{2}{3} RT

Where KE represents the Kinetic Energy, R represents the gas constant and T represents the temperature.

As the kinetic energy increases, the velocity of the gas molecules increases due to which the gas molecule start moving rapidly and hence exerts higher amount of force on the wall of the container in which it is kept.

The higher force leads to generation of higher pressure and hence the higher temperature.

A jogger in July produces large amounts of sweat. Due to this the kidneys change the rate of urine production. Why is this impor
ivolga24 [154]
When it's hot or when the organism starts sweating a lot, this causes an amount of water to be lost from the body. Water is important for the organism to survive and it's absence wi lead to death, therefore Osmoreceptors cells in the hypothalamus in the brain, sends signals to increase the rate of water re-absorption by the kidney. This causes the urine to be of a low volume and more concentrated. This allows enough water to be used by the body as a lot has been lost during sweating.

The answer is A, denature.

As each type of enzymes has its own optimum temperature, like the temperature that they work fastest at, so if the temperature goes too high above the optimum, the 3D structure of the enzyme breaks apart and deforms and they can no longer bind with substrates thus no longer works. In this scenario, we say the enzyme is denatured.

Note that only if the temperature is too high can make the enzyme denature, if the temperature is too low, instead, the enzyme would be inactive, but once the temperature goes back to normal, they work again. Unlike denatured enzymes, which does not work even if the temperature goes back to normal.
