hi teachers,
can u pls help me on this:
Air bubbles produced by divers snorkelling underwater expand and become larger as they rise.
The atmospheric pressure can be assumed to be equivalent to 10m of water.
As air bubble at a depth of 100m below sea level has a radius of 1cm. What is the radius of the new air bubble at a depth of 3.75m below sea level?
Thank you so muchie!
I guess you have to use PV = k or P1V1 = P2V2...
TenSaru is right...
If I'm not wrong, this is an O levels TYS question. Since 2008, I believe the usage of this formula is out of your syllabus.
thank you all for your advise.
i was doing the TYS and thoughthow come i din learn this formula b4.
so confirm out of our syllabus?
yup
you only need to know (graphically as well) and explain the relationship between
i) Pressure & Temperature
ii) Pressure & Volume
iii) Volume & Temperature
Qualitative explanations required, but quantitative no.
At least that was what I read from the syllabus list provided by SEAB, MOE
