@TaylorHogg5 We’re seeing changes all over the world right now with pollution decreasing. Hopefully some countries will see this as a wake up call and we can change our ways. #GlobalEffects

[Sarah @sarahphys273]

@SethWasif It is and it’s been mentioned in multiple other lectures as well

[Sarah @sarahphys273]

They are very catastrophic to our waters.

[Michael Mazzilli @MichaelMazzill3]

Oil spills have a tricking effect on the environment and society #lesson10

[Sarah @sarahphys273]

There are two types of pollutants:
Primary air pollutants- come directly from some human source
Secondary air pollutants- derived through chemical reactions from these primary pollutants
#Lesson10

[Sarah @sarahphys273]

I’m surprised I’ve never heard of ENERGY STAR before this class. Let’s hope more people will know about this so we can all contribute to #EnergyEfficiency

[Sarah @sarahphys273]

@Peter_Phys273 @lpiccolo2332 The lesson is quite interesting, you’ll learn things that’ll help you to conserve energy at home.

[Sarah @sarahphys273]

The Government of Canada website shows you the products eligible for ENERGY STAR! https://t.co/r5OoHxaNF5 #Appliances

[Sarah @sarahphys273]

@lpiccolo2332 Too bad not everyone knows about this.

[Sarah @sarahphys273]

@syed_tahzib I don’t think anyone who lives here is too surprised haha.

[Sarah @sarahphys273]

There are three types of heat transfer:
1. Conduction
2. Convection
3. Radiation
#Lesson9

[Sarah @sarahphys273]

I didn’t know what that star meant until #Lesson9

[Tahzib.Syed @syed_tahzib]

I will try my best to purchase products with the "Energy Star" symbol on them from now on :) ! #lesson9 #phys273

[Sarah @sarahphys273]

Don’t get confised between the Law of Concervation of energy and #EnergyConservation they’re not the same thing.

[Sarah @sarahphys273]

Not a good sign that we haven’t been able to move spent fuel in long term secure underground storage. #RadioactiveWaste

[Sarah @sarahphys273]

@agnesagathiadis Very tragic accident.

[Sarah @sarahphys273]

I always thought nuclear energy was more dangerous from the other forms. However I was wrong the chances of accidents occurring are minimal. #NuclearAccidents

[Sarah @sarahphys273]

Bad timing for the nuclear energy industry😬

[Boosra Alam @BoosraA]

It was quite surprising to learn that a fictional movie had influenced the public's attitude towards the Three Mile Island incident! #Lesson8 #phys273

[Sarah @sarahphys273]

Anyone know why the total fraction of nuclear generation is projected to decrease overall? #NuclearPower

[Sarah @sarahphys273]

@MaxHearn5 I was also very surprised by that I had no idea.

[Sarah @sarahphys273]

@Phys273N Very interesting I didn’t know that.

[Sarah @sarahphys273]

Interesting how for the energy flow of a power plant contains two types of kinetic energy, the kinetic energy of fragments and the kinetic energy of generator. #NuclearEnergy
