Explanation:
Gases: more space therefore meaning that particles in the gas have the highest Kinetic energy therefore moving faster all around.
Liquid: they have more kinetic energy than liquid,but they have some space for movement so they collide each other quicker due to lack of space.
solids: They have least kinetic energy as they have no space at all meaning particles can move around and only just vibrate against each other.
Group.... because elements in a group have same chemical properties
A. Scientific results presented by a scientist should be reproducible anywhere in the world, without this, the results can not be accepted as theory.
V = c \Lambda
7 x 10^16 = 3 x 10^8 / lambda
lambda = 42.85
Kinetic energy is from speed, motion, and mass while potential energy is stored energy
