  1. 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]    Imagen de la pregunta 1
    1. Alets out
    2. Babsorbs
    3. Cdoes nothing with
    4. Dlight.
    5. Eheat.
    6. Ffood.
    7. Genergy.
  2. 2Label this diagram of an endothermic reaction by dragging the correct words to the orange dots.Imagen de la pregunta 2
    1. ALight Energy
    2. BHeat Energy
    3. CChemical Energy
    4. DReactants
    5. EStarters
    6. FProducts
    7. GMultipliers
    8. HProducts
    9. IReactants
  3. 3If you have to put in more energy than you get out, then the reaction is endothermic.Imagen de la pregunta 3
    1. AVerdadero
    2. BFalso
  4. 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."    Imagen de la pregunta 4
    1. Ainside
    2. Boutside
    3. Cwithin
    4. Din the middle
  5. 5Tick the example that is not an endothermic reaction!Imagen de la pregunta 5
    1. AMelting Ice CubesImagen de la opción A
    2. BBaking BreadImagen de la opción B
    3. CBurning SugarImagen de la opción C
    4. DSplitting a gas moleculeImagen de la opción D
  6. 6Endothermic reactions can be used for everyday purposes. For example, certain sports injury cold packs
    use endothermic reactions.    Imagen de la pregunta 6
    1. AVerdadero
    2. BFalso
  7. 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].Imagen de la pregunta 7
    1. Aexothermic
    2. Bendothermic
    3. Clight
    4. Denergy
    5. Efuel
    6. Fheat
  8. 8Combustion is an endothermic reaction.Imagen de la pregunta 8
    1. AVerdadero
    2. BFalso
  9. 9Endothermic means that during the reaction [blank_start]molecules[blank_end] have moved from a lower state of energy to a higher state.Imagen de la pregunta 9
    1. Aatoms
    2. Bparticles
    3. Cmolecules
  10. 10An endothermic reaction results in....Imagen de la pregunta 10
    1. Aa change in temperatureImagen de la opción A
    2. Ba change in heatImagen de la opción B
    3. Ca change in appearanceImagen de la opción C
