Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements.
Explanation:
Answer: 63.6 u
Explanation:
RAM = RAM of isotope-1 X (% abundance) + RAM of isotope-2 X (% abundance) ÷ 100
63 X 70% + 65 X 30% ÷ 100 = 63.6 u
Explanation:
We should have an invariant point condition (The degree of freedom F=0 as per phase rule) for a quadruple point to occur and to test whether this argument is valid or not we must implement phase rule in a given case.
So, as per the Phase Principle F= C-P+2 Here in this situation all types are allotropic implying they consist of the same chemical compound, i.e. each have the same chemical composition.
Then constituents C=1, P= 4 (because they have 4 phases) Also no parameters for the given system are 2, Pressure and Temperature, these are found by including 2 in the formula of phase rule
Therefore, F= 1-4+ 2=-1 is certainly not equal to 0 and therefore the claim that they found a quadruple point is counterfeit.
