One of the science fiction magazines is having a call for conference topics. You decide to submit the following topic: ''what would the world be like if solid water (ice) was denser than liquid water?"
Create a brief synopsis and include a brief discussion on the following issues: how you think the world would be different and the implications for aquatic life.© BrainMass Inc. brainmass.com October 24, 2018, 7:56 pm ad1c9bdddf
Well it would surely be different! Everywhere and anywhere where temperatures at any time would allow water to freeze the situation for life, especially life in water, would be seriously affected. The interesting fact is that the molecular structure of liquid normal water makes it densest at + 4 C (=277 Kelvin). Below 0 C (=273 Kelvin) ice (frozen water) is so much less dense than liquid water (at any temperature, except when the water is boiling - then the steam bubbles will make the fluid on average so less dense that ice will ...
Guidance to Questions on Alternatives to Petrol Fuels
Need to write a critical review about the attached published article, with respect to the prospects for renewable energy in the transportation sector, can you please help and make it simple as I have read the article over and over again, hopefully about 400 words in total should be enough to answer each point below thanks.
Apologies but this is all I can offer for total credits, unfortunately I have just a part time job and brainmass gives me that opportunity to have things explained a lot more clearer for me to understand, I wish I can offer more but I can't sadly, I ask for 400 words no more, thanks for your support.
Please can you base your review on the following guideline questions:
How have the authors formulated the problem/issue?
Do the authors refer to the work of others that they do not agree with?
What are the key concepts or the main factors or variables discussed?
What are the relationships between these key concepts, factors or variables?
What evidence is lacking, inconclusive, contradictory or too limited?
What, if any, evidence might seem unsatisfactory and why?
In what ways does this article contribute to your understanding of the role of renewables in a sustainable energy system?
