Answer:
Line A
Explanation:
In consideration of Charles's law of gases, temperature is directly proportional to pressure of the gas.
Answer:
Net outward force exerted on the window = 45.931_KN
Explanation:
In the hurricane, the pressure outside the window = 0.910_atm
Pressure inside the sealed house = 1.02_atm
Size of windows sides = 2.03_m
But pressure = force/area
Therefore, force = pressure × area
Where 1.00 atm = 1.01 × 10^5 Pa
0.910_atm = 1.01 × 10^5 Pa × 0.910 = 0.9220575_Pa
Also 1.02_atm = 1.03 × 10^5 Pa
Area of widow = 2.03^2 = 4.12_m^2
Force on the outside of the window = 0.9220575_Pa × 4.12_m^2 = 379.971_KN
Force on the inside of the window = 1.03 × 10^5 Pa × 4.12_m^2 = 425.9 KN
Net outward force exerted on the window = 425.9_KN - 379.971_KN = 45.931_KN
Net outward force exerted on the window = 45.931_KN
The answer is C.
Smoke is defined as a colloid, which is any substance consisting of particles substantially larger than atoms or ordinary molecules. It is a suspension of solid and or liquid particles in the air.
Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
