A flexible balloon contains 0.400 molmol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 7150 cm3cm3 and a temperature of 28.0 ∘C∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅KCp=33.26J/mol⋅K and γ=4/3γ=4/3. What is the total heat Q supplied to the gas in the process?
Q =
{\rm J}
Part B
What is the total change in the internal energy DeltaU of the gas?
DeltaU =

\rm J
Part C
What is the total work W done by the gas?
W =\rm J
Part D
What is the final volume V?
V =
{\rm m^3}

this is poiselle's equation from fluid mechanic in physics. mech eng

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

d. platinum would have the greatest temperature increase because it has the lowest specific heat.

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
