At room temperature oxygen, is present in the gas phase.
A gas is defined as a substance which is characterized by the rapidly movement of molecules which are widely separated. The shape and volume of gas is not definite that is they take on the shape of the container in which it is placed. The gas molecules have minimum inter-nuclear attractions and thus have high kinetic energy.
Thus, the sentences that describes oxygen at room temperature are:
- It has no definite volume and takes the shape of its container.
- Its particles move fast enough to overcome the attraction between them.
- It has more energy than it would be at a cooler temperature as the kinetic energy is directly proportional to the temperature that is kinetic energy increases on increasing the temperature.
C - Analyze data and draw conclusions. After an experiment or in this case; an investigation, you would analyze your data that you collected from the investigation/experiment, and draw conclusions based on your data.
P1 x V1 P2 x V2
______ = ________
T1 T2
1260 x 23 / 200 = 144.9
1595x V/300
144.9= 1595x V/300
144.9 x 300/1595 = v
