bonds
200
Energy can NOT be ____________ or ______________
Energy can NOT be created or destroyed
Bonus: it can be transferred and converted
200
What is specific heat?
The amount of energy required to heat up 1g of a substance by 1 degree
200
What's the difference between the system and surroundings?
System is the chemicals and energy involved in a reaction, surroundings are everything else
200
What is the little plastic thing at the end of shoelaces called?
The aglet
300
Temperature measures average ___________ energy of molecules
kinetic
300
What type of heat transfer is through circulation?
Convection
300
What does this symbol mean?
Delta
The Greek letter Delta means "change in"
300
Are bonds formed or broken in exothermic reactions?
They are formed!
300
How many years has Miss Parsons worked as a teacher?
7 years
400
When a chemical bond is broken, the energy is converted into ___________ and released into the surroundings
thermal kinetic energy, heat, kinetic energy
400
Which heat transfer is through direct contact?
Conduction
400
What is one factor that affects how much the temperature changes? (Hint: there's an equation that helps)
Heat added/removed, specific heat, mass of the substance
400
Explain why endothermic reactions feel cold to the touch
Thermal kinetic energy from the surroundings is absorbed and converted into potential energy stored in bonds
400
Where is another place Miss Parsons has lived (besides Texas)?
Massachusetts, Colorado, Italy, Mexico
500
Why is gasoline used as fuel for a car? (Or, why is food fuel for us?)
There is energy stored in the bonds of compounds that the car/we consume. Cars/we are able to break those bonds and convert the potential energy into kinetic energy to be used
Energy conversion
500
What is the third type of heat transfer?
Radiation
500
Which substance will increase in temperature faster: granite or basalt? Why?
Granite - it has a lower specific heat
500
Which graph represents an exothermic reaction?
B
