If an equal mass of sugar and aluminum were poured into separate containers, which would require the smaller container?
2 answers:
Answer:
Aluminum
Explanation:
It is given that:
Mass of sugar = Mass of aluminum
The volume occupied by the two substances can be deduced from their densities.
Density of a substance is a constant and given by the ratio of its mass to volume.
Density of aluminum = 2.7 g/cm3
Density of Sugar = 1.59 g/cm3
Since the masses are equal we have:
Volume of Aluminum = 0.59 (Volume of sugar)
Therefore, aluminum will require a container of smaller volume

Answer:
The volume will be 568.89 mL.
Explanation:
Boyle's law says that "The volume occupied by a given gaseous mass at constant temperature is inversely proportional to pressure"
Boyle's law is expressed mathematically as:
Pressure * Volume = constant
or P * V = k
Gay-Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. That is, the pressure of the gas is directly proportional to its temperature. Gay-Lussac's law can be expressed mathematically as follows:
Where P = pressure, T = temperature, K = Constant
Finally, Charles's law indicates that as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. In summary, Charles's law is a law that says that when the amount of gas and pressure are kept constant, the quotient that exists between the volume and the temperature will always have the same value:
Combined law equation is the combination of three gas laws called Boyle's, Charlie's and Gay-Lusac's law:
Studying an initial state 1 and a final state 2, it is fulfilled:
In this case:
- P1= 960 mmHg
- V1= 550 mL
- T1= 200 C= 473 K (being 0 C=273 K)
- P2= 830 mmHg
- V2= ?
- T2= 150 C= 423 K
Replacing:
Solving:
V2= 568.9 mL
<u><em>The volume will be 568.89 mL.</em></u>
