A soda in a styrofoam cup with a lid, coffee in a thermos with the lid closed is the isolated systems.

<h3><u>Explanation: </u></h3>

Styrofoam cups and thermos containers are typical examples of containers that don’t allow the transfer of heat energy in their environments. A system is said to be isolated if it doesn’t allow heat exchange with its surroundings. A Styrofoam cup with a lid keeps the coffee hot due to its insulation properties.

Thermos container is a more effective insulator since it is made of double-walled container to lock either heat or cold inside. Insulators create effective isolated system depending on the materials they were made from. A completely isolated system does exist.
