A classmate claims that state of matter is an extensive property because it can vary with temperature. For example, hydrogen changes into a liquid at very low temperatures and high pressure, while iron can melt into a liquid at very high temperatures. Do you agree with the classmate? Write an argument to support your position.

The air is going to come out because of the low pressure.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
