Answer:
wind
Explanation:
this is because the others when burnt releases large amounts of carbon of carbon dioxide as they are carbon based and oxidises when burnt. However wind is renewable and converts the kinetic energy in the wind to electrical energy by the use of a turbine
Answer:
a. T₂ = 901.43 ° K
b. T₂ = 843.85 ° K
Explanation:
Given
η = 0.165 mol , Q = 690 J , V = 280 cm³ , P = 3.40 x 10 ⁶ Pa , T₁ = 700 ° K
Using the equation that describe the experiment of heat
Q = η * Cv * ΔT
a.
Nitrogen Cv = 20.76 J / mol ° K
ΔT = T₂ - T₁
T₂ = [ Q / ( η * Cv) ] + T₁
T₂ = [ 690 J / ( 0.165 mol * 20.76 J / mol ° K ) ] + 700 ° K
T₂ = 901.43 ° K
b.
Nitrogen Cp = 29.07 J / mol ° K
T₂ = [ Q / ( η * Cv) ] + T₁
T₂ = [ 690 J / ( 0.165 mol * 29.07 J / mol ° K ) ] + 700 ° K
T₂ = 843.85 ° K
Answer:
196
Explanation:
subtract 24 from 220 to get your answer.
<span>Convection means the movement happens inside a fluid
by the cause of too much heat and lesser density to rise, and also the colder
cause denser materials to sink.
Thus, Solid cannot undergo convection because the molecules inside the solid
are closer and can hardly move unlike liquid.
So, when the temperature got hotter or colder, the molecules on solid will only
vibrate and not convert.
Therefore, this concludes that the solid do not undergo convection rather
conduction of heat.</span>
From my notes it’s the ability to do work
