Answer: Hydrogen molecules will have greatest average speed.
Explanation:
The formula for average speed is :
R = gas constant
T = temperature
M = Molecular Mass
Now putting all the values:
Thus average speed of hydrogen is 8 times the average speed of oxygen. Thus hydrogen molecules will have greatest average speed
Use photomath. I would really recommend it! Hope this helps!
The correct answer is A. The image shows a nuclear fission. This takes place in any of the heavy nuclei after capture of a neutron. This is the opposite of nuclear fusion. In this case, nuclei are broken down into two.
Answer:
solid has definite shape and volume.
liquid do not have definite shape but have definite volume.
gas do not have definite shape and definite volume.
solid have lowest compressibility out of three, liquid have more compressibility than solid but less than gases. gases have the highest compressibility out of three. Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy. The temperature of a substance is a measure of the average kinetic energy of the particles.
