Using the information given, gas-A is still completely unknown.
Answer: No
Explanation:
The force F required is equal to the Force exerted in stretching the first material since conditions are the same
Answer:149.73 ml
Explanation:
Given

change in volume is given by

![\Delta V=\nu_{initial}\beta _{acetone}\left [ T_f-T_i\right ]](https://tex.z-dn.net/?f=%5CDelta%20V%3D%5Cnu_%7Binitial%7D%5Cbeta%20_%7Bacetone%7D%5Cleft%20%5B%20T_f-T_i%5Cright%20%5D)
![V_{final}=\nu_{initial}+\nu_{initial}\beta _{acetone}\left [ T_f-T_i\right ]](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3D%5Cnu_%7Binitial%7D%2B%5Cnu_%7Binitial%7D%5Cbeta%20_%7Bacetone%7D%5Cleft%20%5B%20T_f-T_i%5Cright%20%5D)
![V_{final}=150+150\times 1.50\times 10^{-4}\left [ 20-32\right ]](https://tex.z-dn.net/?f=V_%7Bfinal%7D%3D150%2B150%5Ctimes%201.50%5Ctimes%2010%5E%7B-4%7D%5Cleft%20%5B%2020-32%5Cright%20%5D)
