48
Q

Greenhouse gas

A

Atmospheric gases that intercept long-wave radiation emitted from the Earth’s surface. They contribute to global warming

49
Q

Short term implications of using greenhouse gases

A

Rain pattern change
Evaporation increase
Glaciers melt
Sea level rises

50
Q

Long term implications of using greenhouse gases

A

Warmer atmosphere
Warmer and more acidic oceans
Higher sea levels
More intense heat waves

51
Q

Implications of using greenhouse gases on living organisms

A

Habitat fragmentation
Loss/Reduce availability of food, clean air and water
Changes of the desired climate
Increase of ocean acidification affects marine wildlife which some organisms cannot survive in.

52
Q

Air Pollution

A

The contamination of the indoor or outdoor environment by chemical, biological or physical agents and changes the natural environment or atmosphere

53
Q

How does carbon affect the environment

A

Coats the leaves of plants and reduces the rate or photosynthesis which kills them and reduces production of O2 in the world

54
Q

Controlled Variable in titration

A

Concentration - Dilution, Degradation
Amount of indicator added
Type of acid/base
Parallax error

55
Q

Combustion cleanliness

A

Short chains burn clean
5+ burn dirty

56
Q

How does carbon monoxide affect living organisms

A

Carbon Monoxide is a poisonous gas for living things as it reduces the oxygen carrying capacity of blood
