Answer 1

Answer:

the weather conditions prevailing in an area in general or over a long period.

Answer 2

Explanation:

As flask starts to heat the volume inside the gas starts expanding in all direction due to increasing temperature and the pressure inside and outside the flask are

same as both the atmospheric pressure

-- >Let the volume be V

Parameters. Initial. Final

Temperature 27°C=300K. 477°C=750K

Pressure 1 atm. 1 atm

Volume. V1=V. V2=?

Conversion:-. °C=273+K

=>To assuming the volume of flask we can apply CHARLE'S law

V1/T1=V2/T2

V1/V2=300/750

V2/V=750/300

V2=2.5V

Volume of air expelled=V2-V1

=>2.5-V

=>1.5V

Fraction of air expelled=1.5V/2.5V

=>0.6V
