What is volume?
100
A force that opposes the sliding motion between two touching surfaces.
What is friction?
100
The attraction between the molecules of two different substances in contact with each other.
What is adhesion?
100
The process of heat transfer through the flow of a heat substances such as air or water.
What is convection?
200
The increase in volume caused by a decrease in external pressure.
What is expansion?

300
The attractive force between objects; the force that causes objects to be pulled to the centre of the earth.
What is gravity?
300
The resistance of a fluid to flow.
What is viscosity?
300
The use of gas in an enclosed system under pressure.

400
The process of changing liquid to a solid by removal of heat.
What is solidification?
400
A from of any matter that can flow.
What is a fluid?
400
The amount of force on an object due to gravity.
What is weight?
400
The amount of force applied over a given area to an object.
What is pressure?
400
The tendency of objects in fluids to rise or sink because of density differences with their surroundings.
What is buoyancy?
500
The process of changing state from a solid to a liquid.

500
The amount of space that an object takes up when placed in a fluid.
What is displacement?
500
The pushing or pulling force that acts on certain materials and compounds such as iron, nickel and cobalt.
What is magnetic?
500
The speed at which a fluid flows from one point to another.
What is flow rate?
500
The atmospheric pressure at sea level.
What is one atmosphere.
