What is a question about a study of glass bottles and aluminum cans that scientist would not be able to answer?

c) What is a question about a study of glass bottles and aluminum cans that science would not be able to answer? (2 points) A question about glass bottles and aluminum cans scientist might not be able to answer would be, What container is more preferred.

Which is better for the environment glass bottles or aluminum cans?

Ultimately, the lifecycle analysis considers glass bottles more environmentally friendly due to their lower greenhouse gas emissions that aluminum cans, which are estimated to result in 1.88 times more emissions.

What are two other things the students should look at before evaluating which container is better for the environment?

The first thing they should look at is whether a box can be reused or recycled. Recycling plays a significant role in reducing pollution and also adds economic value. It also reduces the amount of material thrown into landfills. Secondly, they have to see how much carbon dioxide will be generated to sell the product.

Is glass more recyclable than cans?

According to The Aluminum Association, cans are typically made with 70 percent recycled content, and people recycle their cans 20 percent more often than they recycle glass. The major downside to cans comes from making new aluminum.

What factors influence the environmental effect of a container?

Landfilling and littering of more than 135 beverage cans and bottles each year.

  • Energy Consumption. When beverage containers are wasted, they must be replaced with new bottles and cans made from virgin materials.
  • Greenhouse Gases.
  • Toxic Emissions.
  • Litter.

What would make the results of this experiment reliable?

A measurement is reliable if you repeat it and get the same or a similar answer over and over again, and an experiment is reliable if it gives the same result when you repeat the entire experiment.

How do glass bottles affect the environment?

Glass produced from recycled glass reduces related air pollution by 20% and related water pollution by 50%. Recycling glass reduces the space in landfills that would otherwise be taken up by used bottles and jars. Using glass for recycling means there are less glass objects lying around in he landfill or bin.

Why are bottles better than cans?

Because beer cans limit exposure to both light and oxygen, they keep the beer inside fresh and flavorful for longer. When beer is exposed to ultraviolet (UV) light for extended periods, it leads to oxidization and an unpleasant “skunky” flavor in the beer. Glass bottles block out some light, but not all.

How does cans affect the environment?

Because of the processes involved in making them, cans also contribute less to environmental problems like acid rain and oxygen-free zones in the ocean. That’s because creating glass and plastic requires more electricity, and so it generates more sulphur dioxide pollution on average – a leading cause of acid rain.

How do aluminum cans affect the environment?

Smelting aluminum emits greenhouse gases and toxins including carbon dioxide, fluoride, sulphur dioxide, dust, polycyclic aromatic hydrocarbon, and toxic effluents.

How does aluminum affect the environment?

Large parts of both the aquatic and terrestrial ecosystems are affected.In the aquatic environment, aluminium acts as a toxic agent on gill-breathing animals such as fish and invertebrates, by causing loss of plasma- and haemolymph ions leading to osmoregulatory failure.

How can research reliability be improved?

Here are six practical tips to help increase the reliability of your assessment:

  1. Use enough questions to assess competence.
  2. Have a consistent environment for participants.
  3. Ensure participants are familiar with the assessment user interface.
  4. If using human raters, train them well.
  5. Measure reliability.

Do glass and aluminum beverage bottles perform the same in cooling scenarios?

The cooling scenarios were modeled with the COMSOL program to provide a visual representation of how the mechanisms of heat transfer were affecting the bottles. The experimental results showed that the glass and aluminum beverage bottles have similar thermal performances in warming and cooling environments.

What did beer bottles look like in the past?

Next, glass bottles were introduced to the beer scene. These bottles are not the same bottles consumers use today; these bottles usually had a rounder, flask-like shape and were stopped with a cork. These bottles evolved into the cylindrical bottles made of dark glass with metal caps that are popular today.

What raw materials are used to make glass bottles?

It’s safe to say that the raw materials that go into making glass bottles are widely available in the U.S. New aluminum cans are almost always made from bauxite, a mineral that the U.S. gets from mines in countries like Guinea and Australia. The mining of bauxite is harsh on the planet.

Why does aluminum have different thermal properties than glass?

Aluminum has different physical properties than glass which yields to different thermal performances for the different materials. For instance, the thermal conductivity of aluminum is much greater than the soda-lime glass used in bottles.
