Answer:

  • First job out of college was in an industrial manufacturing setting.  Was told by plant engineer to walk around, get used to normal sounds.  He stressed anything "abnormal" is <u>a noise more so than a sound. </u> Report abnormalilies to supervisor immediately!!  So essentially sounds are giving us warnings something is abnormal.
  • Sounds also provide feedback.  Say you are performing an experiment, requires boiling water to sanitize.  Start the burner under a vessel, go on about other preparations.  Sound of water boiling will trigger setting a timer for how long to let it boil.
  • Get off work, pleasant music, nature sounds can help us decompress from a stressful day on the job.

Hope some of these give you impetus to think of other bullet points, sounds good to me.  !!

Answer:

2.33 mL

Explanation:

Given data

  • Initial pressure (P₁): 1 atm (Standard pressure)
  • Initial volume (V₁): 80.0 mL
  • Initial temperature (T₁): 273.15 K (Standard temperature)
  • Final pressure (P₂): 92.0 atm
  • Final volume (V₂): ?
  • Final temperature (T₂): 460°C + 273.15 = 733 K

We can find the new volume using the combined gas law.

\frac{P_1 \times V_1 }{T_1} = \frac{P_2 \times V_2 }{T_2}\\V_2 = \frac{P_1 \times V_1 \times T_2 }{T_1 \times P_2}\\V_2 = \frac{1 atm \times 80.0mL \times 733K }{273.15K \times 92.0atm}=2.33 mL
