It looks like you are categorizing different scenarios and reactions based on their thermal properties and energy changes. Here’s how you might categorize the items you've mentioned:
Left-side Graph (Endothermic Processes):
-
Ice from the freezer's dispenser falls on your kitchen floor and melts into a little cold puddle of water.
- This is an endothermic process because it absorbs heat from the surroundings to melt the ice, leading to a cool sensation.
-
A system that "feels cold or cool" to the touch.
- This is typically indicative of an endothermic reaction where heat is absorbed from the environment, making the surface feel cool.
Right-side Graph (Exothermic Processes):
- Combustion reaction of a match burning in the presence of oxygen.
- This is an exothermic process as it releases energy in the form of heat and light when the match burns.
Summary:
- Endothermic (Left-side): Melting ice from the freezer, cooling sensation.
- Exothermic (Right-side): Combustion of a match.
This categorization helps to understand the energy exchange and temperature changes associated with each scenario.
