Question

rohan and his family are driving to south padre island for spring break. rohan’s mom puts her closed thermos full of coffee in the car before they leave. which of the following best describes the thermos system? (1 point) a radiant system a closed system an isolated system an open system

Explanation:

A closed system is one where matter cannot enter or leave, but energy (like heat) can. The Thermos is closed, so no coffee (matter) escapes, but heat can transfer (energy exchange), fitting a closed system. A radiant system isn't a standard thermodynamic system type here. An isolated system would exchange neither matter nor energy (Thermos isn't perfect insulator, so energy can transfer). An open system allows matter and energy exchange (Thermos is closed, so not open).

Answer:

B. a closed system
