The movement of liquids and gases is generally referred to as a flow,” A concept that describes how fluids behave and how they interact with their surrounding environment .
Answer:
An apple,a person.a table,a computer,wood because they occupies space
non matter=Light, heat, kinetic and potential energy, and sound are non-matter because they are massless
Answer:
These are the isotopes of same element. i.e. hydrogen.
Explanation:
Protium and deutrium are the isotopes of hydrogen.
Isotope:
Atoms of same elements can have different atomic mass but same atomic number . These atom of an elements are called isotopes.
Hydrogen consist of three stable isotopes protium, deutrium and tritium.
These three isotopes are represented as H¹₁ , H²₁ and H³₁ respectively.
Protium consist of one proton and one electron while deutrium consist of one proton , one neutron and one electron. The number of neutron and proton is called mass number while number of electron or proton is called atomic number. The number of proton and electron are always same.That's why protium and deutrium have same atomic number but different atomic mass because there is no neutron present in protium that's why its atomic mass is less than by one from deutrium.
They all have 2 elections in the outer S orbital, and 4 electrons in the P orbitals.
Answer:
Explanation:
Density can be defined as mass divided by volume. But 2 objects made of the same material will have the same density regardless of their volume.
