Answer:
V₂ = 1.51L
Explanation:
According to Boyle's law:
P₁V₁ = P₂V₂
From the given parameter
P₁ = 153kPa
V₁ = 3.00L
P₂ =304kPa
V₂ = ?
Making V₂ the subject of the formula, we have:
V₂ = P₁ V₁/P₂
V₂ = 153 ₓ 3/304
V₂ = 1.51L
Answer:
537.68 torr.
Explanation:
- We can use the general law of ideal gas:<em> PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and V are constant, and have different values of P and T:
<em>(P₁T₂) = (P₂T₁).</em>
P₁ = 485 torr, T₁ = 40°C + 273 = 313 K,
P₂ = ??? torr, T₂ = 74°C + 273 = 347 K.
∴ P₂ = (P₁T₂)/(P₁) = (485 torr)(347 K)/(313 K) = 537.68 torr.
Answer:
soil A mixture of weathered rock and decayed plants and animals. Plants need soil to grow. Soil is the top layer of Earth's land surface, in many places.
