I believe the correct answer from the choices listed above is the second option It is during sublimation that molecules directly move from state to state involving a vibration of particles in a fixed position to a state involving random movement of high speed particles. It <span> is the transition of a substance directly from the solid to the gas phase without passing through the intermediate liquid phase. </span>
Answer:
The final energy is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system= {Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
Explanation:
Answer:
divide 10 by 50.
Explanation:
Because its time over speed 10/50
