The soft, clay-rich rock known as shale, when subjected to pressure becomes a harder rock called slate. ... Even coal can be metamorphosed; bituminous (soft) coal, a sedimentary rock, can be changed into anthracite, or hard coal.
Answer:
19.39 mL.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
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 P are constant, and have different values of V and T:
<em>(V₁T₂) = (V₂T₁)</em>
<em></em>
V₁ = 22.8 mL, T₁ = 48°C + 273 = 321 K,
V₂ = ??? mL, T₂ = 273 (standard temperature = 273 K),
- Applying in the above equation
<em>(V₁T₂) = (V₂T₁)</em>
<em />
∴ V₂ = (V₁T₂)/(T₁) = (22.8 mL)(273 K)/(321 K) = 19.39 mL.
