16 cm^3 b of fuel mixture into 1cm^3 the pressure changes from1 atm

P₂ = 0.94 atm

Explanation:

Given data:

Initial volume = 16 cm³

Final volume after mixing the initial volume into 1cm³ = 16 cm³ + 1 cm³ (17cm³)

Initial pressure = 1 atm

Final pressure = ?

Solution:

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

P₂ = 1 atm × 16 cm³  / 17cm³

P₂ = 16 cm³ . atm / 17cm³

P₂ = 0.94 atm

Pressure will change from 1 atm to 0.94 atm.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

it is the most commonly accepted one
