The answer is A because it does
Answer:
The final temperature of the given ideal diatomic gas: <u>T₂ = 753.6 K</u>
Explanation:
Given: Atmospheric pressure: P = 1.0 atm
Initial Volume: V₁ , Final Volume: V₂ = V₁ (1/10)
⇒ V₁ / V₂ = 10
Initial Temperature: T₁ = 300 K, Final temperature: T₂ = ? K
For a diatomic ideal gas: γ = 7/5
For an adiabatic process:
![\left [\frac{V_{1}}{V_{2}} \right ]^{\gamma-1 } = \frac{T_{2}}{T_{1}}](https://tex.z-dn.net/?f=%5Cleft%20%5B%5Cfrac%7BV_%7B1%7D%7D%7BV_%7B2%7D%7D%20%5Cright%20%5D%5E%7B%5Cgamma-1%20%7D%20%3D%20%5Cfrac%7BT_%7B2%7D%7D%7BT_%7B1%7D%7D)
![\left [10 \right ]^{\frac{7}{5}-1 } = \frac{T_{2}}{300 K}](https://tex.z-dn.net/?f=%5Cleft%20%5B10%20%5Cright%20%5D%5E%7B%5Cfrac%7B7%7D%7B5%7D-1%20%7D%20%3D%20%5Cfrac%7BT_%7B2%7D%7D%7B300%20K%7D)
![\left [10 \right ]^{\frac{2}{5} } = \frac{T_{2}}{300 K}](https://tex.z-dn.net/?f=%5Cleft%20%5B10%20%5Cright%20%5D%5E%7B%5Cfrac%7B2%7D%7B5%7D%20%7D%20%3D%20%5Cfrac%7BT_%7B2%7D%7D%7B300%20K%7D)
<em><u>Therefore, the final temperature of the given ideal diatomic gas</u></em><em>:</em> T₂ = 753.6 K

In a physical change, the substance just changes the state or physical form without affecting the chemical composition of the substance. Some examples of physical change are phase transitions (melting, evaporation), crushing a bottle, the process of dissolution and so on.
Among the given options, the physical form of the ball of clay changes only when the ball is broken into two separate halves and the ball of clay is flattened into a pan-cake like shape. There would be no change in physical form or state when the ball is thrown into the air or rolled along the ground.
So, the correct answer will be: d. II and IV only
