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?

Carbon diselenide (CSe2) is a liquid at room temperature. The normal boiling point is 125°C, and the melting point is –45.5°C. C
Tema [17]

Answer:

Explanation:  The strengths of the inter molecular forces varies as follows -

        CO_{2}< CS_{2} < CSe_{2}

The normal boiling point of CSe2 is 125°C and that of CS2 is 116°C, which explains the trend that as we move down the group, the boiling point of e compound increases as the size increases.

This usually happens because larger and heavier atoms have a tendency to exhibit greater inter molecular strengths due to the increase in size . As the size increases, the valence shell electrons move far away from the nucleus, thus has a greater tendency to attract the temporary dipoles.

And larger the inter molecular forces, more tightly the electrons will be held to each other and thus more thermal energy would be required to break the bonds between them.

A 10.0 ml portion of 0.010 m hcl is diluted by adding it to100.0 ml of water. what is the ph of the solution
Volgvan

From the calculation, the pH of the solution after dilution is 3.

<h3>What is the pH?</h3>

The pH is the hydrogen ion concentration of the solution. Now we know that;

C1 =  0.010 m

V1 = 10.0 ml

V2 = 10.0 ml + 100.0 ml = 110 ml

C2 = ?

C1V1 = C2V2

C2 = C1V1 /V2

C2 =  0.010 m  * 10.0 ml / 110 ml

C2 = 0.00091 M

pH = -log[0.00091 M]

pH = 3

vagabundo [1.1K]

Answer:

Explanation:

0.00580=5.8*10^-3

3000=3.0*10^3

0.000908=9.08*10^-4

200.=2.0*10^2
