It is formed when magma of </span>granite<span> composition erupts at the earth's surface or intrudes the crust at shallow depths. It is used as an abrasive material in hand soaps, emery boards, etc.</span>
Answer:
Incomplete combustion of fuels produces a very poisonous gas called carbon monoxide:Excessive inhaling of carbon dioxide gas can kill a person.
I don't know if this is correct, your question did not have much context.
T is important to go through a fluid phase as it is being produced because the object must go through heat to be melted and then it should be put into a mold to be formed. Also, it go though heat to keep it from cracking and go to be cooled and harden.

Answer:
17.03Pa
Explanation:
Given parameters:
Initial volume = 15.5kL
Final volume = 6kL
Final pressure = 44Pa
Unknown:
Original pressure = ?
Solution:
The parameters given shows pressure and volume relationship of the given gas. One of the gas laws that predicts pressure - volume relationships is the Boyle's law.
Boyle's law states that "the volume of a fixed mass of gas varies inversely as the pressure changes, if the temperature is constant".
Mathematically,
P₁V₁ = P₂V₂
where P₁ is the initial pressure
V₁ is the initial volume
P₂ is the final pressure
V₂ is the final volume
Input the variables and solve for P₁;
P₁ x 15.5 = 44 x 6
P₁ = 17.03Pa
