During the Industrial Revolution, life changed dramatically as a result of technological advancements, urbanization, and changes in social structures. There was a shift from rural agricultural economies to urban industrial centers, leading to the growth of cities and the rise of factories. The standard of living improved for many as new goods became more affordable, but working conditions were often harsh and labor movements emerged to demand better rights for workers.

What are IR-active and inactive molecules?
In order for a molecule to be IR active, the vibration must produce an oscillating dipole. This usually means that the bond (or bonds) in question have are polar to begin with so that they have a dipole. Therefore symmetrical molecules like O2 and N2 are not IR active, but molecules like H2O with polar bonds are IR active.
Why are some vibrational modes of benzene IR inactive?
Some vibrational modes of benzene involve a change in electric dipole moments. These are IR active modes. Some vibrational modes have no net change in dipole moment (which is true for most of the modes since benzene is a planar symmetrical molecule) when they stretch, so they are IR inactive. There are 30 vibrational modes for benzene altogether, 8 of which are IR active. Some vibrational modes of benzene involve a change in electric dipole moments. These are IR active modes.

Transparent material for IR?
One common transparent material for infrared (IR) radiation is sapphire, which is often used in IR windows and lenses due to its clarity over a wide range of wavelengths. Other materials, such as germanium and zinc selenide, are also widely used for IR applications due to their transparency in the IR spectrum.
Why KBr using in IR?
KBr is transparent to IR radiation, most alkali halides are transparent in ir
What is the difference between IR and FT IR instruments?
A standard IR runs a single spectrum. An FT-IR uses an interferometer and makes several scans and then uses Fourier Transforms to convert the interferogram into an infrared spectrum.
Why is IR critical in the search for life elsewhere?
IR as in infrared? Who says it is "critical"? Search for life elsewhere in the Galaxy, or here on Earth?
What changes with the electric current?
Since V=IR then the answer would be voltage and/or resistance.AnswerIn the equation, V = IR, resistance is a constant -so it does not change with a change in current.
How did change life change for during the neolithic ages?
Life changed for people during the Neolithic Age because that was when they found out how to make fire.
Why positive terminal of megger is grounded during IR measurement of electrical equipments?
during ir test we are grounding the positive terminal to avoid osmosis effect.
What is a change of shape during a frogs life?
It is Metamorphosis.
Did prawns change their gender during their life time?
No, prawns do not change gender during their lifetime. They are born either male or female and remain the same gender throughout their life.
Do football players on IR receive Super Bowl rings?
Yes. Because a player that is on IR has at some point during the season been active and gotten hurt during a game and has been placed on IR to heal up from say a dislocated shoulder or knee surgery
Why do people get animals during a change in their life?
God knows
What does IR do?
makes your Iron Renic play cool in life and be famous
