Polyethylene gets harder as the number of carbon atoms increases.

Density increases as you go deeper into the earth.

Proper exercise will improve both. This is a better answer: we breath in more oxygen and we have to respire quickly. Our heart has to pump the oxygenated blood around around our body faster and take the deoxygenated blood to the lungs to get the carbon dioxide out.

let it sit out in the air after a couple of days it will get harder
iron with 1.5% of carbon by volume or less is called carbon steel and above 1.5% it is called cast iron, hardmess increases with the carbon % i.e. cast iron is harder than carbon steel
Too much carbon dioxide will kill any animal or human. We need oxygen to live. As the levels rise, the need for air increases and a person will begin to breathe harder and deeper. If the levels get even higher, they will try to get out of the room or become unconscious.
Since the frictional force is directly proportional to the normal reaction When two surfaces are pressed harder normal reaction increases .'. Friction increases
because natural emeralds are harder than a synthetic emareld
no
increases evasivenes. i.e. make it harder for you to be hit
It increases it and causes the heart to work harder.
If your car originally had full synthetic, then you should go with that. But if it came with regular/conventional oil then it wouldn't be smart to switch unless you have it flushed out because it can cause carbon build-up inside, which will make the motor run harder and heat up more.
