What happens to the oceanic crust at a deep ocean floor

1 answer:

3 0

Mid-ocean ridges and seafloor spreading can also influence sea levels. As oceanic crust moves away from the shallow mid-ocean ridges, it cools and sinks as it becomes more dense.

Answer:

protons in the atom.

Explanation:

The identity of an element relies on the number of protons in its atom. This is called the atomic number. The atomic number is the basis of the periodic table of elements. Modern periodic law states that "the properties of elements are a periodic function of their atomic number".

Atomic number of atoms do not change and they are convieniently used in identifying an atom.

enyata [817]

Answer 1) : The density of the hot air inside the balloon can be found out by using ideal gas equation;

PV = nRT;

As n is number of moles and in gases, number of moles along with mass per mole is equal to the density of the gas.

If the moles in the gas are more the density will be more.

here, density (ρ) = mass (m) / volume (V); substituting in the ideal gas equation we get,

ρ = mP / RT

Answer 2) ρ (hot air) = ρ (cold air) X $\frac{T_{h}}{T_{c}}$
