How does increasing and decreasing the temperature affect the kinetic energy of molecules? How does this impact heat

coldgirl [10]

Answer: As the temperature of a molecular system increases, the kinetic energy of molecules also increase. Also as the temperature of a molecular system decreases, the kinetic energy of the molecules will also decrease.

Explanation:

James Clerk Maxwell developed the kinetic-molecular theory (KMT) of gases. In this theoey, five assumptions concerning an ideal gas was made. One of the them was that," the average kinetic energy of the gas molecules is proportional to the temperature of the gas". This simply means that a s the temperature of a molecular system increases, the kinetic energy of molecules also increase. Also as the temperature of a molecular system decreases, the kinetic energy of the molecules will also decrease.

Also another scientist known as Rudolf Clausius incorporated energy into the kinetic theory. He proposed that heat is a form of energy that affects the temperature of matter by changing the motion of molecules in matter.

Heat is defined as the flow of energy which is caused by difference in temperature.

In conclusion, when the temperature of a system is increased, the collision of the molecules with one another and the walls of their container increases as more molecules gain more heat energy at higher temperature. While as the temperature of the system decreases, the collision of the molecules will also decrease as molecules lose heat energy at lower temperature.

What evidence is Earth's Geological timescale mostley based from?

SCORPION-xisa [38]

Answer:

B. Geological Events and Lifeforms

Explanation:

The Earth's Geological time scale is mostly based on Geological Events and Lifeforms.

The Geological time scale provides a division of events on the earth into several time frames.

Each of the time units are based on events through the Earth's history and evolution of life.

The events are often recorded in rock strata and also as fossils which are the preserved remains of organisms.

Compound X has a molar mass of 135.13 and the following composition: element mass % carbon 44.44% hydrogen 3.73% nitrogen 51.83%

geniusboy [140]

Hello!

First, let's see what a molar mass is. A molar mass is how much a mole weighs, or how much 6.02214076×10²³ of an element weighs.

Now, let's find the molar mass of each of these three elements.

Carbon: 12.0107 g/mol

Hydrogen: 1.00784 g/mol

Nitrogen: 14.0067 g/mol

Now, see how much of the molar mass of compound x each of these contributes.

Carbon: 44.44% * 135.13 = 60.051772 g/mol

Hydrogen: 3.73% * 135.13 = 5.040349 g/mol

Nitrogen: 51.83% * 135.13 = 70.037879 g/mol

Finally, calculate how many atoms there are in the molecule. Do this my dividing the "how much they contribute to the molar mass" by the molar mass.

Carbon: 60.051772 / 12.0107 = 5

Hydrogen: 5.040349 / 1.00784 = 5

Nitrogen: 70.037879 / 14.0067 = 5

Therefore, we know that there are 5 Carbons, 5 hydrogens, and 5 nitrogens.

Put this all together to get the molecular formula: C5H5N5 (note that the numbers should be written as subscript)

Hope this helps!
