1In thermodynamics, the term endothermic process describes a process or
reaction in which the system [blank_start]absorbs[blank_end] energy from its surroundings;
usually, but not always, in the form of [blank_start]heat.[blank_end]
- Alets out
- Babsorbs
- Cdoes nothing with
- Dlight.
- Eheat.
- Ffood.
- Genergy.
2Label this diagram of an endothermic reaction by dragging the correct words to the orange dots.
- ALight Energy
- BHeat Energy
- CChemical Energy
- DReactants
- EStarters
- FProducts
- GMultipliers
- HProducts
- IReactants
3If you have to put in more energy than you get out, then the reaction is endothermic.
- AVerdadeiro
- BFalso
4The term was coined by Marcellin Berthelot from the Greek roots endo-, derived from the word
"endon" (ἔνδον) meaning "[blank_start]within[blank_end]" and the root "therm" (θερμ-) meaning "hot."
- Ainside
- Boutside
- Cwithin
- Din the middle
5Tick the example that is not an endothermic reaction!
- AMelting Ice Cubes
- BBaking Bread
- CBurning Sugar
- DSplitting a gas molecule
- AMelting Ice Cubes
6Endothermic reactions can be used for everyday purposes. For example, certain sports injury cold packs
use endothermic reactions.
- AVerdadeiro
- BFalso
7Breaking bonds (overcoming the force of attraction) requires [blank_start]energy[blank_end]. You have to put heat in - it is endothermic. This is why melting and boiling are [blank_start]endothermic[blank_end].
- Aexothermic
- Bendothermic
- Clight
- Denergy
- Efuel
- Fheat
8Combustion is an endothermic reaction.
- AVerdadeiro
- BFalso
9Endothermic means that during the reaction [blank_start]molecules[blank_end] have moved from a lower state of energy to a higher state.
- Aatoms
- Bparticles
- Cmolecules
10An endothermic reaction results in....
- Aa change in temperature
- Ba change in heat
- Ca change in appearance
- Aa change in temperature
