Hello miss. Thanks you so much your video was really useful to me😊 can I ask if whether we could be asked how to find the diameter of the tube to find the area or will it be given to us
@MissEstruchBiology2 жыл бұрын
HEllo, no I have not seen that before. The piece of apparatus should inform you on purchase the diameter size.

she responded to a question like this on instagram, and mentioned that questions could be asked on either method so its safest to learn both (rough method etc) :)

Wouldn't decreasing the volume increase the pressure in the experimental tube, causing the fluid to move towards the control group?
@MissEstruchBiology2 жыл бұрын
It's decreasing the volume on content inside the tube, not the actual size of the tube. So the tube volume is the same, but volume of gas inside of it has decreased which is why the pressure decrease. Hope that helps
