Unit 10: How can our Energy resources be accessed fairly? Flashcards
1
Q
Combustion
A
- Hydrocarbons react with oxygen
- Forms water and carbon dioxide
- Fire
- Exothermic reaction
- Blue Flame
2
Q
Flash Point
A
- Lowest temperature at which it will combust if given ignition
3
Q
Ignition Temperature
A
- Lowest Temperature at which it will spontaneously burst into flames
4
Q
Incomplete Combustion
A
- Not Enough Oxygen or fuel
- Carbon Monoxide is formed
- Yellow Flame
5
Q
Endothermic
A
- Heat Energy in Products>Reactants
- Takes in energy from surroundings
6
Q
Exothermic
A
- Heat Energy in Reactants>Products
- Lets out energy
7
Q
Bond Breaking
A
- Endothermic Process
8
Q
Bond Making
A
- Exothermic Process
9
Q
Delta T
A
Corrected Temperature change (max -min) when reactant is added
10
Q
Specific Heat Capacity
A
Amount of energy required to increase 1kg of substane's temperature by 1 degree celsius - Q = m x c x deltaT Q = Heat Energy m = mass c = specific heat capacity DeltaT = Change in temperature
