In this task, you will use an engineering design method to create two solar ovens. Here’s one way to approach an engineering design:

Define the problem.
List the potential solutions.
Pick the best solution and build it.
Test the solution.
Improve the design.
Estimated time to complete: 3 hours

You will need these materials:

2 thermometers that reach at least 120°F (50°C)
2 boxes of any size that the thermometer will fit inside
Optional materials you might need to complete your designs:

plastic wrap
aluminum foil
paper
scissors or a box cutter
ruler
masking tape or clear packaging tape
glue
Stay safe! Work slowly and carefully with the scissors so you do not cut yourself. Handle thermometers carefully. Remember, they are breakable. Thermometers can contain hazardous materials. If you break a thermometer, ask for an adult’s assistance to clean it up. Construct all solar ovens outdoors in an open area.

Design, Build, and Test
Part A

In this activity, you will construct two solar ovens and use thermometers to determine which oven gets the hottest. What engineering problem are you trying to solve?

The following three equations represent reactions done in this lab exercise. Classify each reaction by their type. Note there ma
gulaghasi [49]

Answer: 1. Cu(s)+4HNO_3(aq)rightarrow Cu(NO_3)_2(aq)+2NO_2(g)+2H_2O(l) : oxidation reduction

2. Cu(NO_3)_2(aq)+2NaOH(aq)\rightarrow Cu(OH)_2(s)+2NaNO_3(aq) : precipitation

3. CuO(s)+2HCl(aq)\rightarrow CuCl_2(aq)+H_2O(l) : Double displacement

Explanation:

Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

Oxidation reaction is defined as the reaction in which a substance looses its electrons. The oxidation state of the substance increases.Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

Cu(s)+4HNO_3(aq)rightarrow Cu(NO_3)_2(aq)+2NO_2(g)+2H_2O(l)

Double displacement reaction is defined as the reaction where exchange of ions takes place. Double displacement reaction in which one of the product remain in solid form are represented by (s) after their chemical formulas. Such double displacement reaction are called as precipitation reaction.

Cu(NO_3)_2(aq)+2NaOH(aq)\rightarrow Cu(OH)_2(s)+2NaNO_3(aq)

Double displacement reaction is defined as the reaction where exchange of ions takes place.

CuO(s)+2HCl(aq)\rightarrow CuCl_2(aq)+H_2O(l)

Single displacement reaction is defined as the reaction where more reactive element displaces a less reactive element from its chemical reaction.

Decomposition reaction is defined as the reaction where a single substance breaks down into two or more simpler substances.

Synthesis/Combination reaction is defined as the reaction where substances combine in their elemental state to form a single compound.
