The choices can be found elsewhere and as follows:
<span>A 10 timesB 2 timesC 4 timesD 8 timesE 16 times
I believe the correct answer from the choices listed above is option E. If you turn up the temperature of an oven from 250 degrees kelvin to 500 degrees, the oven will be radiating 16 times.</span>
The higher you go upwards the cooler it becomes.
Since the troposphere is the lowest layer of the atmosphere, it will be the warmest.
C. Troposphere
The official web site of the Nobel Prize explains that Marie Curie’s chemistry prize was partly for her discovery that the radioactivity of a substance is unaffected when it undergoes a chemical reaction. The discovery implied was that, Radioactivity involves Radioactivity involves only neutrons.
Explanation:
- The official web site of the Nobel Prize explains that Marie Curie’s chemistry prize was partly for her discovery that the radioactivity of a substance is unaffected when it undergoes a chemical reaction. The discovery implied was that, Radioactivity involves only neutrons.
- Marie Curie studied about the radiation of all compounds containing the known radioactive elements, including uranium and thorium, which she later discovered that they were radioactive.
- she discovered the following results,
- the exact measurement of the strength of the radiation from uranium;
- the intensity of the radiation was found to be proportional to the amount of uranium or thorium in the compound .
- the ability to emit radiation is not dependent on the arrangement of the atoms in a molecule;
- it must be linked to the interior of the atom itself which is a revolutionary discovery.
