Answer:
P₂ ≅ 100 atm (1 sig. fig. based on the given value of P₁ = 90 atm)
Explanation:
Given:
P₁ = 90 atm P₂ = ?
V₁ = 18 Liters(L) L₂ = 12 Liters(L)
=> decrease volume => increase pressure
=> volume ratio that will increase 90 atm is (18L/12L)
T₁ = 272 Kelvin(K) T₂ = 274 Kelvin(K)
=> increase temperature => increase pressure
=> temperature ratio that will increase 90 atm is (274K/272K)
n₁ = moles = constant n₂ = n₁ = constant
P₂ = 90 atm x (18L/12L) x (274K/272K) = 135.9926471 atm (calculator)
By rule of sig. figs., the final answer should be rounded to an accuracy equal to the 'measured' data value having the least number of sig. figs. This means P₂ ≅ 100 atm based on the given value of P₁ = 90 atm.

Answer:
Matter always takes space (or has volume).
Energy is released by the formation of chemical bonds, and energy is
absorbed when the bonds are broken.
<h3>What is a chemical reaction?</h3>
A chemical reaction involves the formation of new compounds from
reactants . It involves the formation and breaking of bonds in the
elements.
Energy is released by the formation of chemical bonds and this type of
reaction is referred to as exothermic while energy is absorbed when the
bonds are broken and is referred to as an endothermic reaction.
