1. Design Solutions A camping gear company is planning to manufacture a portable solar oven that has a footprint of 40 cm × 40 cm (length × width). The company has hired you to consult on the design. What suggestions would you make to help ensure that thermal energy transfer in the solar oven is maximized? Use the simulation data from the virtual lab to support your answer.


2. Evaluate Information: In your simulated experiments, you tested the effects of four different design variables on the performance of a solar oven: window size, box height, box thickness, and the use of reflectors. Identify two other variables that you think affect the performance of a solar oven. For each variable, make a prediction about its effect on the oven’s maximum temperature.

Answers

Answer 1

Answer:

1. The solar cooker must have a cover to trap all of the heat to make the food heat up faster. Usually clear glass or plastic is used to cover the heat.

Disadvantage of a solar cooker is that it is very expensive. It does not work without sunlight. Hence, on cloudy day, it becomes useless. The places where the days are too short or places with cloud covers round the year, have limited utility for solar cooker.

Explanation:

Stop reclaiming land: Stop reclaiming land from estuaries. Limit pollution: Help to keep the estuary healthy by not adding solid waste or liquid pollution. Don't pour harmful substances such as oil, detergent or paint into an estuary or allow these materials to go down stormwater drains that lead to estuaries. It provides a home to specially adapted marine plants and animals. Those organisms, in turn, serve as food for many other animals. The intertidal zone also staves off erosion caused by storms. Oyster reefs are one such example of a protective feature.
