Kinetic energy of the particles is the measure of energy of the molecules when they are in motion. Kinetic energy is increased when phase change occurs from solid to liquid to gas. Solid has a rigid state which disables the particles to move unlike that in gas and liquid state where liquids can move more because of the spaces in between them.
Answer:
1.056 miles are equal to 1.7km
Answer:
12
Explanation:
If you look at the periodic table, you can see that magnesium has an atomic mass of 24.305. Subtract the number of protons from this to get neutrons.
24.305 - 12 = 12.305
12.305 is the average amount of neutrons a magnesium atom can have. A magnesium atom can have 12, 13, or 14 neutrons. The average, based on the natural abundance, is 12.305. To find which isotope is more abundant, you need to pick the number that is closest to the average. This would make the most abundant isotope the one with 12 neutrons.
