Answer:
Density of CO₂ at STP = 1.96 g/L
Explanation:
1 mol of any gas at STP occupies 22.4L of volume.
The rule for the Ideal gases.
Assume 1 mol of CO₂, we know that has 44 grams of mass.
Density = mass / volume
44 g/ 22.4L = 1.96 g/L
The mass of the blimp is 1.12 kg.
<em>Step 1</em>. Calculate the<em> volume of the blimp</em>.
<em>V</em> = 6.28 × 10⁹ mm³ × (1 m/1000 mm)³ = 6.28 m³
<em>Step 2</em>. Calculate the <em>mass of the helium</em>.
Mass = 6.28 m³ × (0.1786 kg/1 m³) = 1.12 kg
The correct answer is option d, that is, colder and denser.
The surface currents refer to the currents at the surface of the water, to a few hundred meters deep, while deep currents refer to the currents when the density increases to a greater extent.
The surface current takes place close to the surface and move horizontally. This kind of currents are caused by global winds, an example of surface current is Gulf Stream. On the other hand, deep current takes place in the ocean and is affected by the density of water, temperature, and salinity. An example is Antarctica Bottom Water. In comparison to surface currents, deep currents are colder and denser.
Answer:
Up to 80 - 120 days.
Explanation:
The flower will probably stay six to twelve days or so.
I'm not sure what's your hypothesis going to be, but I'll give you an example.
" <em>If</em> I __________, <em>then</em> the sunflower will grow up to 80 to 120 days."
In the blank space, you can write what you're going to do to your sunflower during the experiment.
Please correct me if I'm wrong.
Answer:
The answer to the question is
The height of the mercury fluid column remain the same.
Explanation:
The pressure, P in a column of fluid of height, h is given by
P = (Density p)×(height of fluid column h)×(gravity g)
Therefore, when the diameter is doubled we have
Density of the mercury in the tube with twice the diameter = (Mass of mercury)/(volume of mercury) where the volume of mercury = h×pi×(Diameter×2)^2/4 = h×pi×Diameter^2. Therefore the volume increases by a factor of 4 and therefore the mass increases by a factor of 4 which means that the density remains the same hence
P = p×h1×g = p×h2×g Therefore h1 = h2
The height of the fluid column remain the same
