Endothermic and Exothermic ReactionsSlide2
Which one is easier to make happen?
Building a sand castle?
Destroying a sand castle?Slide3
How about these?
Wrecking your snowman?
Building as snowman?Slide4
And these?
Making a cake?
Making a mess?Slide5
What does Baking a cake, building a snow man, or making a sand castle have in common?
Making bigger things from smaller things
Making less things (one snow man) from more things (lots of snowflakes)
Requires energy or effort to doSlide6
What does eating a cake, Wrecking a snowman or sandcastle have in common?
Breaking into smaller pieces
Breaking into more pieces
Comparitvely
, doesn’t take as much effort or energy as building or making itSlide7
Exo
therimic
- Heat or energy is released as one of the products
It will get
WARM/HOT
Think of the word EXIT
Endo
thermic- Heat or energy is required as one of the reactants
It will get
COOL
