Answer:
I'd say its speed but not to sure
Explanation:
<em>Answer:</em>
<em>B.) A hot liquid or air that expands, becomes less dense, and rises or becomes more dense and sinks.</em>
<em>Explanation:</em>
<em>Convention is the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.</em>
Answer: 8.33 mol of HCl (Hydrochloric Acid)
Explanation:
150 g H2O x __1 mol__ x __1 mol HCl__ = 8.33 mol of HCl
18.016 g 1 mol H2O
Heat is needed to change solid to liquid even to gas!
The buoyancy of an object is dictated by its density. So let us calculate for density, where:density = mass / volume
Calculate the volume first of a solid cube:volume = (6 cm)^3 = 216 cm^3 = 216 mL
Therefore density is:density = 270 g / 216 mLdensity = 1.25 g / mL
Therefore this object will float in the layer in which the density is more than 1.25 g / mL.
