I have my hot drink in a cup. It is in a CONDUCTOR. Tell me what makes sense with the temperature as the time passes.
It will get colder faster. Example (Starts at 100 degrees and goes down to 70 degrees) Got colder faster. Not good for a hot drink.
I have my hot drink in a cup. It is in an INSULATOR. Tell me what makes sense with the temperature as the time passes.
The temperature will change SLOWLY. My drink will start at 100 degrees f and change maybe to something slightly less warm like 90 degrees f.
What is Unit 2 about?
