Sentences with phrase «radioactive elements inside»

If the original asteroids were bigger than about 20 kilometers across — and there's no reason to think they weren't — decaying radioactive elements inside them would have made the rock hotter than that.
By measuring the amount of radioactive elements inside Earth, the detector can study how the planet formed.

That water is saltier than seawater and may contain naturally occurring arsenic and radioactive elements trapped inside rock formations deep underground.
These measurements may also shed light on the proportion of radioactive elements like uranium and thorium inside the Moon, since their decay produces heat and should increase the amount of heat radiated by the Moon, says Paul Spudis of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, US, who is developing radar instruments to fly on LRO and Chandrayaan - 1.
If you put a radioactive element into lukewarm soup in a Dewar flask in order to maintain its temperature and put the flask into a refridgerator, then the outside skin of the Dewar would be lower than the inside skin which would be lower than the soup temperature.
Since energy is constantly being added from the decay of the radioactive elements in the planet's core, the temperature inside a perfect reflector would rise until the reflector melted.
SImple experiment: put a sample of a radioactive element (which has a measured temperature) inside of a Dewar flask and measure if the temperature of the radioactive element rises as a result of radiative reflection from the inner walls of the flask.
