Answer: The pressure of a gas will increase when there is a decrease in the volume of the gas.
Explanation: according to Boyle's law, the volume of a gas will decrease when the pressure is increased at constant temperature and vice versa.

The oxidation number of V and Al in each ion is +3 and +4 respectively.
<h3>What is oxidation number in chemistry?</h3>
oxidation number, also called oxidation state, the total number of electrons that an atom either gains or loses in order to form a chemical bond with another atom.
<h3 /><h3>Why is it called oxidation number?</h3>
The term oxidation was first used by Antoine Lavoisier to signify the reaction of a substance with oxygen. Much later, it was realized that the substance, upon being oxidized, loses electrons, and the meaning was extended to include other reactions in which electrons are lost, regardless of whether oxygen was involved.

Answer:
0.99 m³
Step-by-step explanation:
This looks like a case where we can use the <em>Combined Gas Law </em>to calculate the volume
p₁V₁/T₁ = p₂V₂/T₂ Multiply both sides by T₁
p₁V₁ = p₂V₂T₁/T₂ Divide each side by p₁
V₁ = V₂ × p₂/p₁ × T₁/T₂
<em>Data:
</em>
p₁ = 201 kPa; V₁ = ?; T₁ = 27 °C = 300.15 K
p₂ = 2.5 kPa; V₂ = 59.3 m³; T₂ = -14 °C = 223.15 K
<em>Calculation:
</em>
V₁ = 59.3 × 2.5/201 × 300.15/223.15
V₁ = 20 × 0.0124 × 1.345
V₁ = 0.99 m³
