The pressure of a gas is proportional to it's temperature and the volume of water.
<h3>What is gas pressure?</h3>
The pressure of a gas is the force it exerts per unit area on the walls of its container.
The pressure of a gas is proportional to the temperature of the gas. The higher the temperature, the higher the pressure and vice versa.
The pressure of a gas is also proportional to the volume of water in the container. The larger the volume of water , the higher the pressure.
Therefore, the pressure of a gas is proportional to it's temperature and the volume of water.

For the ones that don’t need numbers, I will put 1, but choose what you personally learnt:
(1), 2, 2, (1), 2
I believe putting 1 would be the best option I have, just incase
Answer:
Copper ions are reduced into copper atoms.
Cu²⁺₍aq₎ + 2e⁻ → Cu₍s₎
Explanation:
During electrolysis, the positive H⁺ and Cu⁺ ions move to the negative cathode and negative OH⁻ and Cl⁻ ions move to the positive anode.
At cathode, copper ions are preferentially discharged due to the low electromotive force required to discharge them compared to the hydrogen ion. The copper ions gain the two electrons lost by the chloride ions when the are discharged. (2 Cl⁻₍aq₎ → Cl₂₍g₎ + 2e⁻)
Thus the half equation is as follows:
Cu²⁺₍aq₎ + 2e⁻ → Cu₍s₎
Dry air is a mixture of nitrogen, oxygen, carbon dioxide etc.
