4 Questions
How is the density of air determined using a round-bottomed flask?
By attaching the flask to a vacuum pump and measuring the change in mass and volume of air removed
What is the purpose of opening the clip of the round-bottomed flask underwater?
To allow water to replace the vacuum in the flask
What is the role of the sensitive top-pan balance in determining the density of air?
To measure the mass of the round-bottomed flask with and without air
Why is a round-bottomed flask used in determining the density of air?
To standardize the volume of air being tested
This quiz covers the method of finding the density of air using a round-bottomed flask, stopper, and vacuum pump. It involves measuring the mass of the flask with and without air to determine the mass of the air inside.
