Matter are anything that is made up of atoms. The quantity of matter can be observed only on the basis of mass and volume calculation. Therefore, humidity in grams/cubic meter is 19.5.
Matter is a substance that has some mass and can occupy some volume. The matter is mainly used in science. Matter can be solid, liquid or gas.
Matter is anything that is made up of atoms. Anything around us that can be physically seen and touched are matter. Ice, water and water vapors are example of matter.
So as we saw that matter has some mass so mass can be measured in gram only. Mass can also be represented as number of molecules. We also saw that matter occupy some volume and that volume is measured only in liter.
humidity =30 × 65% =19.5 grams/cubic meter
Therefore, humidity in grams/cubic meter is 19.5.

Answer:19.5 grams/cubic meter
Explanation:30 times 65% search it it equals 19.5
Answer:
Crushing or grinding increases the surface area of the salt that is exposed to the molecules of water. Stirring increases the speed at which the particles of salt come in contact with the water molecules.
Electopositivity is the measure of the ability of elements to donate electrons to form positive ions. Whereas the Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Group 1 is more electropositive than group 17 and group 17 is more electronegative than group 1.
Answer: Finding out that asbestos is dangerous and limiting its use in building materials
Explanation:
(2) The atom’s radius decreases and the atom becomes a positive ion.
(3) The atom’s radius increases and the atom becomes a negative ion.
(4) The atom’s radius increases and the atom becomes a positive ion.
When an atom loses an electron, it becomes a positive ion and the radius of the atom decreases. The correct answer is option 2.
An atom is the basic unit of matter that consists of a nucleus, which contains positively charged protons and uncharged neutrons, surrounded by a cloud of negatively charged electrons.
Therefore, option 2. The atom’s radius decreases, and the atom becomes a positive ion is the correct answer.

Answer:
When an atom loses an electron, the atom's radius decreases and the atom becomes a positive ion.
(2) 2-7-8 (4) 2-8-8
The electron configuration that represents the atoms of chlorine in an excited state is 2-7-8. This is because in the excited state, an electron has moved from the second energy level to the third
The electron configuration represents the distribution of electrons in an atom's energy levels. The standard electron configuration for a ground state (normal state) chlorine atom is 2-8-7. However, when an atom is in an excited state, one or more electrons have moved to a higher energy level. In the case of chlorine, an electron from the second energy level could be excited to the third energy level. So, the electron configuration representing an atom of chlorine in an excited state would be option (2) 2-7-8.
