PRESENTATION OUTLINE
The kinetic energy of an object is the energy that it possesses due to its movement
The kinetic theory describes gases as a large number of small particles, all of which are in constant motion
A Barometer is used to measure the air pressure in the atmosphere. It's units are called atmospheres or bars
Blood contains haemoglobin, it is a protein that binds to oxygen in the lungs so that oxygen can easily be transported to the rest of the body
As altitude increases, the amount of haemoglobin increases. More of it will mean more oxygen, but too much and blood will become sticky
As temperature increases, the particles will have more kinetic energy. Less kinetic energy means lower temperature
The air outside the lungs has a greater pressure than the air inside. So it goes where there's less air pressure
Some substances are solid at room temperature due to its viscosity. Some are liquids, because they have less viscosity
There are small gaps between the particles in liquids. In gases, the particles are free to move
