100
The process of changing state from gas to a liquid.
What is Condensation
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 heated substance such as air or water.
What is Convection
100
The process of changing state from a solid to a liquid.
What is Melting
100
The attractive force between objects; the force that causes objects to be pulled around the centre of the earth.
What is Gravitation
200
The mass of a given volume.
What is Density
200
The strength with which the particles of an object or fluid attract each other.
What is Cohesion
200
The study of pressure in liquids.
What is Hydraulics
200
The process of changing state from a liquid to a solid by the removal of heat.
What is Solidification
200
the amount of force applied over a given area to an object.
What is Pressure
300
The process of changing state from a liquid to a gas.
What is Evaporation
300
A push or pull that acts on an object; anything that changes the motion or shape of an object.
What is Force
300
The use of gas ( usually air ) in an enclosed system under pressure.
What is Pneumatics
300
The process of changing state from a solid to a gas without going through the liquid stage.
What is Sublimation
300
The resistance of a fluid to flow; the slower the flow, the greater this is.
What is Viscosity
400
An increase in volume caused by a decrease in external pressure.
What is Expansion
400
Force that opposes the sliding motion between two touching surfaces.
What is Friction
400
The amount of space taken up by a substance or object.
What is Volume
400
The amount of force on an object due to gravity.
What is weight
500
The amount of matter in a substance or an object; the more the matter, the greater this is.
What is Mass
500
a pushing or pulling force that acts on certain metals and compounds; such as iron, nickel, and cobalt.
What is Magnetic
