Part 1 Designing an Investigation
Kobotan [32]

Answer:

The experimental plan is to measure the values of the dependent variable, which is the temperature of the pizza after it is cooled in each of the heat (temperature) environments, which is the dependent variable, for a given equal period of time, which is the control

Explanation:

The given parameters are;

The temperature of the pizza = 400°F

The temperature of the freezer = 0°F

The temperature of the refrigerator = 40°F

The temperature of the countertop = 78°F

Given that the independent variable = The heat to which the hot pizza is subjected

The dependent variable = The temperature to which the pizza cools down

The experiment plan includes;

1) Place the pizza which is at 400°F in each of the different heat environment, which are, the freezer, the fridge, and the counter top, for the same period of time and record the final temperature of the pizza

2) The option that gives the lowest final temperature within the same time frame is the option that will let the pizza cool down fastest.

Explain why copper is used for the<br> roofs of some buildings and magnesium is not.
Scrat [10]

Answer:

Because of the less reactivity of copper.

Explanation:

As well as being resistant to the elements and thereby less likely to be affected by rainfall, hail, and mildew than other types of roofing, copper is also one of the most fireproof materials available. Copper is also highly resistant to thermal changes and thereby doesn't deteriorate quickly.

Magnesium would also corrode PDQ. Magnesium sheeting would also pose an unacceptably high fire hazard.
