What is the difference between a real gas and an ideal gas?

A gas is assumed to behave ideally if it follows the following assumptions:
Gas particles are very tiny so their volume is negligible. So they are considered that do not have a volume.Gas particles move at a constant motion, which means that they do not collide.Gas particles do not interact with each other, therefore, there will be no attraction or repulsion between each other.These are the main points of difference between an ideal gas and a real gas.
For a real gas, all these points are not valid, therefore:
Gas particles occupy a space and therefore have a volume.Gas particles collide with each other and their motion tends to speed up or slow down.Gas particles interact with each other.

Idk the answer imthink snail cant mate they dont lol

100cm, because 11.0 cm is 3 figures as they've chosen to include the decimal point. if you have a 3 digit number then anything after the second digit will become 0 if it's to 2 significant figures
