I really liked how clearly you talked, and the way you put emphasized the points you wanted to. I’m also glad you made yours in video format, as it makes it much easier to watch. I wonder how this science and concept could be applied to a new innovation in the real world?

Thank you for the review! As for your question, thermal conductivity can be used and applied to many different innovations. For example, there may be some material or substance somewhere in the world with incredible insulating powers allowing us to better insulate things like homes, and the same idea of application may be applied if there is a material out there with incredible conducting abilities, the likes of which we have never seen.
Thank you for the feedback,

Hey Kavyan,
I liked how your presentation very easy to understand . For a person like me who knows next to nothing about thermodynamics, presentations like these tend to be much more interesting if they are clear and concise. I think that you were a bit heavy on the transitions. The exciting and flashy transitions on every slide were a bit distracting for me.
Is it possible to control the flow/transfer of heat within a closed loop/”circuit” using the principles you showed in this presentation? How? Is this useful?

Thank you for the feedback. I understand your criticism on the transitions, and I will take it into mind.
As for your question, I do believe that the transfer of heat in a circuit can be controlled. I believe that the simple fact that wasted energy turns into heat may contribute to this theory.
Your question is very in-depth, and this is good, but I fear that I may not be able to answer it to your expectations. I can say that the amount of energy flowing through the circuit as well as the current speed flowing through the circuit may be important variables in answering this question.
In terms of this being useful or not, I believe that the ability to control the transfer of heat through a circuit will contribute to the amount of wasted energy, allowing us to use our power to its maximum efficiency.
Thank you for the feedback and the very interesting question,
Kavyan

Great job Kavyan! I really liked all the information that you presented because you seemed to be well informed about your subject! I found that since you had fewer slides, I was able to focus much more on what you were saying rather than what was on the screen. I also found that your speed while speaking helped get your point across. Based on your research about thermal insulators, which one do you think is the most effective? Overall, I thought you made an effective presentation that was awesome!

Hey Glen! Thanks so much for the feedback.
As for you question, there are many sufficient thermal insulators, such as fibreglass and styrofoam.
Fibreglass is the pink fuzz that you see inside housing walls. You can see an image of fibreglass on the slide where I begin to explain the concept of thermal conductivity. Fibreglass is the most common insulation in housing because of its ability to insulate heat at such a good value. The only problem with this material is that since it is just many finely woven strands of silicon and glass powder, it is harmful to the eyes, lungs and skin if there is no proper safety equipment worn.
On the subject of thermal insulators, I figured that I may mention the material with the lowest heat conductivity I could find: Aerogel. Aerogel has the lowest thermal conductivity among solid objects because of the high porosity, low gas conductivity and low radiative transmission. However, aerogel should not be used casually since it is very expensive. Aerogel comes at a cost of $1 for every cubic centimetre, at about $23k per pound.
Now that I have listed one of the most commonly used insulators, fibreglass, and the material with the lowest heat conductivity, aerogel, I hope that I have given you a sufficient answer to your satisfaction.
Thank you for the feedback,

Hi Kavyan, your video was very clear to understand, especially since we recently touched on this topic in science with Mrs. Mulder. I like the idea of experimenting with different metals to get a feel for it yourself, but I was wondering how exactly these tests would expand your knowledge on this topic? Experiments should give you information that you can’t find online, as it is run by yourself with respective twists. So what are your ideas on this?
-Thank you, AJ

HI Adrian! Thanks for the comment. As for your question, I would firstly like to check if my sources online are credible, but I would also like to check if I 100% understand the information I get online. Doing the experiment will help me better understand the properties of the metals I am testing, such as aluminum foil. I hope this answered your question.
Thank you for the comment,

You did a good job speaking clearly and having little pauses to make it easier for the audience to understand. There wasn’t anything major to change in your presentation so great job Kavyan. I was wondering if there would be any advantages for anything to using a metal that doesn’t conduct heat as well as pure silver with the price put aside.

Hello Ronan! Thanks for the comment. As for your question, the only reason you would want to have a metal that isn’t the best for conducting for conducting purposes is if you wanted to try to keep the rate of heat conductivity within a certain range. For example, maybe the fast conductivity of pure silver is too fast for what you are trying to make. I hope that answers your question.
