Question

A very long, wide sheet of plastic 4 mm thick and initially at 20°C is exposed on both sides. What will be the final temperature of the plastic sheet after exposure? a) 20°C b) More than 20°C c) Less than 20°C d) Cannot be determined with the given information

Answer 1

The final temperature of the plastic sheet after exposure cannot be determined without additional information on environmental conditions and exposure duration.

None of the given answer is correct

Step-by-step explanation:

The final temperature of the plastic sheet after exposure cannot be determined with the given information. The question lacks specific details about the conditions to which the plastic is being exposed, such as the temperature of the environment, the presence of any heat sources or sinks, or the duration of exposure.

In general, the temperature of the plastic will tend towards the temperature of its surroundings over time due to thermal exchange processes, but without additional details, an exact final temperature cannot be predicted.

None of the given answer is correct
