Answer:
- Density Liquid = 0.841 g/mL
- Density Metal = 2.711 g/cm³
Explanation:
- The density of the liquid is:
Mass Liquid / Volume Liquid
From the problem we know that Volume Liquid = 25.0 mL, <u>the mass of the liquid can be calculated by substracting masses</u>:
- Mass Liquid + Mass Slug + Mass Empty Cylinder = 125.934 g
- Mass Liquid + 15.454 g + 89.450 g = 125.934 g
- Mass Liquid = 125.934 g - 15.454 g - 89.450 g
Thus the density of the liquid is:
Density Liquid = 21.030 g / 25.0 mL = 0.841 g/mL
2. The density of the metal slug is:
Mass Metal / Volume Metal
We already know that the mass of the slug is 15.454 g. Its volume can be calculated using <em>Archimede's principle</em>, which states that the volume of an object is equal to the volume of liquid it displaces, in other words:
Volume Metal = 30.7 mL - 25.0 mL = 5.7 mL
Thus the density of the metal slug is
Density Metal = 15.454 g / 5.7 mL = 2.711 g/mL = 2.711 g/cm³
It should be option (A) because conduction is the transfer of heat energy from one place to another by vibrations/motion of the molecules. I hoped I helped.
Answer:
sugars such as dextrose and sucrose increase the surface tension of water. The effect was interpreted as a depletion of the solute molecules from the water-air interface.
The relationship between volume and pressure is described in the Gay-Lussac's law. That is,
P₁V₁ = P₂V₂
Substituting the known values,
(75 mL)(145 atm) = (500 mL)(P₂)
The value of P₂ is equal to 21.75 atm.
