No, a single particle cannot have a temperature at all, because temperature is a property of a large number of particles.- this is not my own words the website I got it from is https://www.quora.com/Can-a-single-particle-have-any-temperature
The volume becomes two. You have to use the equation P1 x V1 = P2 x V2 P is pressure and V is volume. P1 = 50 P2 = 125 V1 = 5 V2 = v (we don't know what it is) Then set up the equation: 50 times 5 = 125 times v 250 = 125v the divide both sides by 125 and isolate v 2 = v Therefore the volume is decreased to 2. Also, Boyle's Law explains this too: Volume and pressure are inversely related, This means that when one goes up the other goes down (ie when pressure increases volume decreases and vice versa). Becuase the pressure went up from 50 KPa tp 125 KPa the volume had to decrease.
The key difference between empirical and molecular formulas is that an empirical formula only gives the simplest ratio of atom whereas a molecular formula gives the exact number of each atom in a molecule.
