QUESTION:
Classify each process as exothermic or endothermic.
(a) dry ice subliming (changing from a solid directly to a gas)
(b) the wax in a candle burning
(c) a match burning
ANSWER:Solution 64P :
Step 1:
Here, we have to classify each process if its exothermic or endothermic. First let’s see what is an endothermic and exothermic process.
An endothermic process is a process or reaction in which the system absorbs energy from its surroundings usually in the form of heat.
An exothermic process is a process or reaction that releases energy from the system to its surroundings, usually in the form of heat, light (ex: a spark, flame, or flash), electricity (ex : a battery), or sound (ex: explosion heard when burning hydrogen).
