A sample is termed REPRESENTATIVE SAMPLE if it has similar characteristics to the population being studied.
The representativeness of a sample is the extent to which its characteristics accurately reflects the characteristics of the population being studied.
If we subtract the atomic number from the weight, we get the number of neutrons in the particle. This is because protons and neutrons each have a weight of 1, while electrons are 0. And since the atomic number is also the number of protons in the atom, subtracting it from total weight gives us the number iif neutrons.
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. "If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.
Answer:
no
Explanation:
they absorb our oxygen by the wind that blows so they can keep alive
