    How to Determine if a Substance is Pure

     · A pure solid has a constant/fixed melting point. ie. it will melt completely at one temperature only. With impurities, the melting point of a substance is affected in two ways: The melting point is lowered. For example, pure ice melts completely at zero degree Celsius but the ice we make at home from tap water will start to melt before zero degree Celsius. The more impurities a substance ...

    Is Pure Altruism Possible?

     · Pure altruism, we think, requires a person to sacrifice for another without consideration of personal gain. Doing good for another person because something's in it for the doer is the very opposite of what we have in mind. Kin selection does better by allowing that organisms may genuinely sacrifice their interests for another, but it fails to explain why they sometimes do so for those with ...

    How To Smelt Metals At Home

    Well, what is going to happen to any base metals exposed in nature or buried underground? Sooner or later, air, water, and heat, acting alone or in combination, are going to turn all metals into very unmetallic minerals. This explains why we almost never find raw metals in nature. There are only a few kinds of metals that we can find pure and metallic in nature (mostly noble metals, and maybe ...

  • Thorium

    Thorium

    Thorium is much more abundant in nature than uranium. Thorium can be used as a nuclear fuel through breeding to uranium233 (U233). When this thorium fuel cycle is used, much less plutonium and other transuranic elements are produced, compared with uranium fuel cycles. Several thoriumfuelled reactor concepts are under consideration.
