A-LEVEL PE (OCR): PAPER 1 - Recovery, Altitude and Heat

These flashcards explain key concepts related to oxygen use during and after exercise, including EPOC (Excess Post-exercise Oxygen Consumption), oxygen deficit, and the two stages of recovery. They highlight how the body restores itself to a pre-exercise state and compensates for oxygen demands during physical activity.

  • More reactive

  • lower melting point

  • lower boiling point

Calcium is a metal, true or false?
True!
Why is it significant that all alkali metals have one outer electron?
It makes them very reactive and gives them all similar properties
Transition metal’s compounds have dull colours, true or false?
False, they are very colourful. For example, potassium manganate(VII) is purple.
Copper is an alkali metal or a transition metal?
It’s a transition metal
Is potassium in group one or two?
One
If rubidium is below potassium in group one of the periodic table, which is more reactive?
Rubidium
Are transition metals good or bad conductors of heat and electricity?
They are good conductors of heat and electricity.
What’s an ore?
A rock that contains enough metal or metal compound to make it economic to extract the metal
How are more reactive metals extracted?
Electrolysis
How are less reactive metals extracted?
Reaction with carbon or carbon monoxide.
How is copper purified?
Electrolysis
What makes copper useful for wiring?
It’s soft so easily bent and a good conductor of electricity.
What makes copper useful for plumbing and making pipes and tanks?
It’s a good conductor of heat and doesn’t react with water.
Can transition metals be bent into shape easily?
Yes
What materials are transition metals useful for?
Construction materials.
What’s an alloy?
A mixture of two or more elements, usually metals.
Why are alloys harder than pure metals?
They contain atoms of different sizes, which distort the regular arrangements of atoms, making it more difficult for the layers to slide over each other.
What do alkali metals all have in common?
They have to be stored in oil and handled with forceps
