Heat is absorbed by all solids as they melt and turn into liquids. As a result, the substance changing states absorbs energy throughout the melting process.

Melting and boiling will result in the absorption of heat energy. In both condensation and freezing, heat energy is released (temperature is lowered), which causes the kinetic energy of molecules to decrease. As a result, gas transforms into liquid and then solid as a result. Endothermic chemical processes are those that generally absorb (or use) energy. When bonds in the reactants are broken in endothermic reactions, more energy is absorbed than is released when new bonds are created in the products. Positive energy is released during condensation and consumed during vaporization (negative energy).

Option A is correct. An electron was promoted from the 2p orbital to the 3s orbital.

The elementary electric charge of the electron, a subatomic particle, is a negative one. Due to their lack of known components or substructure, electrons, which are part of the first generation of the lepton particle family, are typically considered to be elementary particles. The mass of an electron is around one-eighth that of a proton (1/1836). The electron's inherent angular momentum (spin), which is measured in terms of the scaled-down Planck constant,, is one of its quantum mechanical properties. The Pauli exclusion principle states that because electrons are fermions, no two of them may be in the same quantum state.

Electrons, like all elementary particles, have the ability to interact with other particles and behave like waves when they are diffracted, similar to how light does. Since electrons have a smaller mass than other particles like neutrons and protons and a longer de Broglie wavelength for a given energy, their wave characteristics are simpler to see experimentally than those of other particles like neutrons and protons.

Option (a) is correct. Except K shell the maximum number of electrons that can be in the outermost shell of an atom is 8. This is according to the octet rule.

According to the octet rule, the outermost shell in an atom cannot have more than eight electrons even if it has a capacity to take up more electrons. The octet rule is explained as a chemical rule that reflects the theory that the elements tend to bond in such a way that each atom has eight electrons in its valence shell giving it the same electronic configuration as a noble gas. It refers to the the tendency of atoms to prefer to have eight electrons in the valence shell. The octet rule states that atoms are at their most stable when they have 8 electrons in their outermost shell. Atoms tend to try and gain or lose electrons until they have eight electrons in their outer shell.

Answer:

i thinks it is B

Explanation:

The pressure of a given mass of an ideal gas is inversely proportional to volume at constant temperature, according to Boyle's law.

P1V1 = P2V2 = (600mmhg*100.0ml = 800mmhg*V2)

The volume of the gas at a pressure of 800 mm Hg is 75 mL.

This empirical relationship, which Robert Boyle, a scientist, first proposed in 1662, argues that, under constant temperature, the pressure (p) of a given amount of gas changes inversely with its volume (v); in equation form, this means that pv = k, a constant.

According to Boyle's Law, as pressure lowers, gas volume grows. According to Charles' Law, when the temperature rises, the volume of the gas also rises.
