Climate change has always happened on Earth, which is clearly seen in the geological record; it is the rapid rate and the magnitude of climate change occurring now that is of great concern worldwide. Greenhouse gases in the atmosphere absorb heat radiation. Human activity has increased greenhouse gases in the atmosphere since the Industrial Revolution, leading to more heat retention and an increase in surface temperatures. Atmospheric aerosols alter climate by scattering and absorbing solar and infrared radiation and they may also change the microphysical and chemical properties of clouds. Finally, land-use changes, such as deforestation have led to changes in the amount of sunlight reflected from the ground back into space (the surface albedo). It may seem counterintuitive, but
more snowfall during winter storms
is an expected outcome of climate
change. That's because a warmer
planet is evaporating more water
into the atmosphere. That added
moisture means more precipitation
in the form of heavy snowfall or
downpours.
During warmer months, this can
cause record-breaking floods. But
during the winter - when our part
of the world is tipped away from
the sun - temperatures drop, and
instead of downpours we can get
massive winter storms.
Elements in the same group have the same amount of electrons, this affects bonding because it determines how much the element will "want" to form a covalent bond.
The electronic configuration of a ground-state Cr-atom :
1s²2s²2p⁶3s²3p⁶4s²3d⁴
<h3><u>What are electronic configurations?</u></h3>
The arrangement of an atom's or molecule's (or other physical structure's) electrons in their atomic or molecular orbitals is known as the electron configuration in atomic physics and quantum chemistry. For instance, the neon atom's electron configuration is 1s² 2s² 2p⁶, which means that 1, 2 and 6 electrons, respectively, are present in each of the 1s, 2s, and 2p subshells.
According to electronic configurations, each electron moves individually within an orbital while being surrounded by an average field produced by all other orbitals. Slater determinants or configuration state functions are used to mathematically characterize configurations.

According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.
<h3>What is Kinetic molecular theory ?</h3>
Kinetic molecular theory of gases is a theoretical model that describes the molecular composition of the gas in terms of a large number of submicroscopic particles which include atoms and molecules.
According to this theory, gas pressure arises due to particles colliding with each other and the walls of the container.
Because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases.
This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.
Due to the sun's heat, the kinetic energy of particles in the balloon increases and it expands and continues to expand and comes to a stage when the balloon bursts.
Therefore,
According to Kinetic molecular theory, the frozen balloon shrank and it will expands and get burst when it is kept in sun.
