Explanation:
Answer:
492.3 cm³.
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 P and n are constant, and have different values of T and V:
<em>(V₁T₂) = (V₂T₁).</em>
V₁ = 417.0 cm³, T₁ = 65°C + 273 = 338 K.
V₂ = ??? cm³, T₂ = 126°C + 273 = 399 K.
<em>∴ V₂ = (V₁T₂)/(T₁) =</em> (417.0 cm³)(399 K)/(338 K) = <em>492.3 cm³.</em>
Answer:
Irrigation is the artificial process of applying controlled amounts of water to land to assist in production of crops. Irrigation helps to grow agricultural crops, maintain landscapes, and revegetate disturbed soils in dry areas and during periods of less than average rainfall.
Answer:
One way to remove soap from water is to have it react with other substances. When the reactions occur, a solid called a precipitate is sometimes formed. A precipitate can be filtered out of the water.
Explanation:
1 cup sugar; Final soap suds height; 9.1 cm
2 cup Table Salt; Final soap suds height; 1.2 cm
3 cup Epsom salt; Final soap suds height; 0.2 cm
In heating, lighting, washing, watering, entertainment, and cooking.
