which event is endothermic? the burning of a match the change of water vapor to a liquid the combustion of propane gas the melting of ice
Answer
Answer:
D. the melting of ice
Explanation:
Step1: Define endothermic process
An endothermic process absorbs heat from the surroundings.
Step2: Analyze burning of a match
The burning of a match is an exothermic reaction as it releases heat and light.
Step3: Analyze change of water - vapor to liquid
The change of water - vapor to liquid (condensation) is an exothermic process as heat is released when water vapor changes to a liquid.
Step4: Analyze combustion of propane gas
The combustion of propane gas is an exothermic reaction as it releases heat and energy.
Step5: Analyze melting of ice
The melting of ice requires heat to be absorbed by the ice to change from solid to liquid, so it is an endothermic process.
