Using boyles law
p1v1=p2v2
p1=205
p2=?
v1=425
v2=1209
205x425=p2x1209
87125/1209=p2
p2=72kPa
Buoyancy is considered a physical property. It is a type of physical property because it is related to the density and weight of the item, which are both physical.
Answer:
The stopper is not fitted on the flask quickly.
Explanation:
The reaction has to do with a gas. The predicted value of the slope is 1. The value of slope obtained from the experiment varies slightly from the predicted value of 1. This discrepancy may be caused by not fitting the stopper on the flask quickly enough. This means that some gas may still be left in the flask leading a discrepancy in the slope obtained.
