Answer: A container yet to be placed under the sun would be at room temperature (25-27°), which is the temperature of the environment.
Step-by-step explanation:
Heat inceases the temperature of a body, especially when the body is a metallic in nature. There is a tendency that the body gets heated faster being a metal than being any other object. The metal is not only heated but also conduct or transmits the heat to the environment; making the environment hotter than it should.
The temperature of a container before exposed to sun would be cold, containers are metals and metals easily conduct either heat or cold, whatever their environment is, they transmit energy easily, a container yet to be placed under the sun would be at room temperature (25-27°), which is the temperature of the environment.
