Through Charles' Law, we know that volume and temperature have a proportional relationship meaning that if we increase the temperature, the volume will also increase. We can use the following formula: (V1/T1) = (V2/T2)
The equation of Charle's law requires temperature to be in ubnits of Kelvin.
So to find the new temp in kelvin, we use T + 273 so the two temps are 523 and 1123. Now we can plug in our values into the formula
The elements in the periodic table are arranged in columns - elements in the same column exhibit similar properties. Mg and Sr are in the same column (period I) Br and F (period XVII - 17) S and O (period XVI - 16)
