AQA GCSE Physics Unit 1

The gap between the readings in an experiment is called

• Range
• Interval
• Precision
• Accuracy

When you forget to tare a weighing scale with a beaker on before measuring the mass of a powder, you make

• A random error
• An anomalous result
• A systematic error
• A fool of yourself

If you investigate the relationship between the type of surface of a can and the infrared radiation it emits when containing hot water, you must keep all the same but

• The initial temperature of the water
• The surface
• The volume of water
• The temperature of the room

The internal energy of particles is larger in

• A solid
• A gas
• A liquid
• A particle

A change of state from liquid to solid is called

• Condensation
• Sublimation
• Solidifying
• Boiling

This can occur  in vacuum

• Convection
• Conduction
• Sound
• Radiation

The temperature of a glass of water at 4 degrees is placed in a room at 20 degrees. Heat transfer will be

• Into the water
• To the surroundings
• There won't be any heat transfer

The unit of Specific Heat Capacity is

• Kilogram per Joule per Celsius degree
• Joule per kilogram per Celsius degree
• Celsius degree per Joule per kilogram
• Kilometre

You can reduce heat loss from your houses by using

• Loft Insulation
• Black sheets behind radiators
• Single glazing
• Opening the windows

A liquid has

• Fixed shape and volume
• Fixed volume but not shape
• Fixed shape but not volume
• Neither a fixed shape nor a fixed volume
