Answer:
B .It has gravitational potential energy because of its height.
C .Its atoms and molecules have thermal energy.
Explanation:
B. The cylinder has gravitational potential energy; in fact, this is given by
where m is the mass of the cylinder, g is the gravitational acceleration and h is the heigth of the cylinder above the ground. Since the height h is different from zero, it means that the GPE is different from zero.
C. The gas inside the cylinder has thermal energy, because its atoms and molecules constantly move (they have a random motion called Brownian motion), and this kind of energy due to the motion of molecules is called thermal energy.
Answer:
275 kPa
Explanation:
mass of the gas=m=1.5 kg
initial volume if the gas=V₁=0.04 m³
initial pressure of the gas= P₁=550 kPa
as the condition is given final volume is double the initial volume
V₂=final volume
V₂=2 V₁
As the temperature is constant
T₁=T₂=T
=
putting the values in the equation.
=
P₂=
P₂=
P₂=275 kPa
So the final pressure of the gas is 275 kPa.
