Question

The experiment assumes that when bubbles no longer emerge from the tube into the reservoir, the volume of air is equal to the total volume of the experiment chamber and the temperature of the air is equal to the temperature of the boiling water.

Explain why these are reasonable assumptions? Be specific.

Answer 1

Volume of air = volume of experiment chamber

Tempearture of air = temperature of boiling water

a)

for tempearture, we may assume so, since there is no longer heat transfer between each other... that is due to the gradient/change in temperature, if the temperature are equal, no more heat is required

so we ensure T1 = T2

b)

for the volume

we can assume so sinc the volume is fixed and therefore, the volume of water must be alwayus the same as the volume of the reservoir

this way we ansure that any material will occupy the same space/volume
