Team Discussion Questions – 18/03/2015

Question 4 – The concerns of acid rain vary across the globe. Many countries in North America and Europe have websites dealing with acid rain.  Either search to locate one or use these links to website in Canada, the UK, or Europe. What are the issues in the country you selected? Does the acid deposition originate outside the borders of the country?

Answer:

Canada

Damage caused by acid rain deposition affects lakes, rivers, forests, soil, fish and wildlife population and buildings. Acid rain also contributes to lower visibility levels and impacts public health such as increased admissions to hospitals because of respiratory problems. The problem in Eastern Canada: many of the waters and soil in the region lack natural alkalinity; therefore it cannot neutralize acids.

Acid deposition in Canada originates primarily in Southern Ontario and Quebec, but because of the largest undefended border between Canada and the US, both countries contribute to each other’s acid deposition. Additionally, prevailing wind patterns and greater US emissions, US sends much more acidity to Canada than Canada does to it.

MEETING MINUTES 11/03/15

Purpose of meeting: The allocation of work for the second milestone: Chemical Concept & Implications to Society.

Date: 11th March 2015 (Wednesday)
Venue: Outside LT 27
Time: 1530hrs

Attendance

Members present:
Ash
Reesa
Wendy
Cindy
Lionel
Maung

Topics discussed:

  1. To allocate workload for the second milestone – we have chosen to focus on the combustion of fossil fuels and it’s implications in today’s context.
  2. Decided that we should start filming the two videos only after finishing the blog.
  3. Reminded everyone that there is peer evaluation to do, and everyone should actively participate to ease the workload.

Follow-up Action:

  • Lionel to email Prof. to ask when is the dateline for the two videos
  • Chemical Concept & Implications to Society and second meeting log pages have to be done up by Wednesday 18/03/2015. (Everyone)

Any other business:

None

 

Meeting was adjourned at 1615hrs.

Improvement of course

a) The professor’s voice is a little bit soft at times, especially when the lecture theatre is noisy. b) Some of the content in the lecture notes are rather complex and may actually require more advanced understanding of chemistry. e.g. Lewis structure

 

Solution:  a) Use the microphone.  b)The syllabus should be looked into and ensure that the material covered would actually be understandable to students who have absolutely no background knowledge of chemistry.

 

Team Questions Session 3 – 11/02/2015

Q1) Understanding Earth’s energy balance is essential to understanding the issue of global warming. For example, the solar energy striking Earth’s surface averages 168 watts per square meter (W/m2), but the energy leaving Earth’s surface averages 390 W/m2). Why isn’t the Earth cooling rapidly?

Answer: The energy leaving Earth’s surface comprises of both solar energy and energy radiated from Earth. However, the radiation from Earth is huge and trapped by greenhouse gases in the atmosphere. As a result, the earth heats up instead of cooling rapidly.

Q2) Do you think the statement made by the cartoon is justified? Explain.

Answer: Global warming leads to extreme polarities of weather differences. The people in the cartoon falsely assume that global warming only leads to heat-inducing natural processes but this is not true. Hence, snowing does not mean that global warming is not occurring. The statement made by the cartoon is not justified.

Professor’s comment: more about the differences between climate and weather.

Q3) One of the first radar deices developed during the World War II used microwave radiation of a specific wave range that triggers the rotation of water molecues. Why was the design not successful?

Answer: Due to the presence of many water molecules in the air, the microwave radiation decreases when it is ‘attracted’ by these molecules. Less radiation means that there will not be enough energy to deliver the message. Hence, the design is not successful.

 Professor’s comment: water molecules will absorb microwave radiation.

Q4) Now that you have studied air quality (Unit 1), stratospheric ozone deletion (Unit 2), and global warming (Unit 3), which do you believe poses the most serious problem for you in the short run? In the long run?

 

Answer: In the short run, air quality poses a more serious problem for us. Pollutants in the air consists of minute particles so small that are dangerous for our health. for instance, such irritants can cause respiratory problems, which can be deadly if serious. In the long run, global warming is the most serious as its repercussions can be felt and are mostly irreversible. Rising sea levels can be detrimental to communities living in coastal areas, and can displace entire places. Agricultural produce would be affected if the global temperatures rise too high and our basic needs such as food and water would be greatly affected.
