A) Most is transformed into thermal energy. I took the test.
Shape, because a liquid can have mass, volume, and color, but it cannot have a definitive shape
Answer:
As the temperature rises the solubility of all gases in water also will decrease.
Explanation:
The solubility of gases in water increase with the decrease of the temperature, and vice-versa.
The scape of the gas molecules from solution occurs by the breaks of the intermolecular bonds as a consequence of the increase of the kinetic energy which causes an increase in the motion of the gas molecules in solution.
That is why as the temperature rises the solubility of all gases in water also will decrease.
I hope it helps you!
Answer:
The main purpose of the turbine in the turbojet engine is to Drive the compressor.
Explanation:
Answer:
12 m/s
Explanation:
Using the continuity equation, which is an extension of the conservation of mass law
ρ₁A₁v₁ = ρ₂A₂v₂
where 1 and 2 indicate the conditions at two different points of flow, in this case, point 1 is any normal position in the pip and point 2 is the conditions at the restriction.
ρ = density of the fluid flowing; note that the density of the fluid flowing (water) is constant all through the fluid's flow
A₁ = Cross sectional Area of the pipe at point 1 = (πD₁²/4)
A₂ = Cross sectional Area of the pipe at the restriction = (πD₂²/4)
v₁ = velocity of the fluid flowing at point 1 = 3 m/s
v₂ = velocity of the fluid flowing at The restriction = ?
ρ₁A₁v₁ = ρ₂A₂v₂
Becomes
A₁v₁ = A₂v₂ (since ρ₁ = ρ₂)
(πD₁²/4) × 3 = (πD₂²/4) × v₂
3D₁² = D₂² × v₂
But
D₂ = (D₁/2)
And D₂² = (D₁²/4)
3D₁² = D₂² × v₂
3D₁² = (D₁²/4) × v₂
(D₁²/4) × v₂ = 3D₁²
v₂ = 4×3 = 12 m/s
