- Introducing OpenAI o3 and o4-mini
OpenAI o3 is our most powerful reasoning model that pushes the frontier across coding, math, science, visual perception, and more It sets a new SOTA on benchmarks including Codeforces, SWE-bench (without building a custom model-specific scaffold), and MMMU
- What is Ozone? - US EPA
Ozone (O3) is a highly reactive gas composed of three oxygen atoms It is both a natural and a man-made product that occurs in the Earth's upper atmosphere (the stratosphere) and lower atmosphere (the troposphere)
- Ozone Therapy: What It Is, Uses and Side Effects
Ozone (O3) is a molecule made up of three oxygen atoms It’s highly unstable and explosive in liquid or solid form But as a gas, this supercharged oxygen may potentially have therapeutic qualities
- Ozone - American Lung Association
What Is Ozone? Ozone (O 3) is a gas molecule composed of three oxygen atoms Ozone is good up high, bad nearby The ozone layer found high in the upper atmosphere shields us from much of the sun's ultraviolet radiation
- Ozone | Definition, Properties, Air Pollution, Importance, Structure . . .
Ozone is 1 5 times as dense as oxygen; at −112 °C (−170 °F) it condenses to a dark blue liquid, which freezes at −251 4 °C (−420 °F) The gas decomposes rapidly at temperatures above 100 °C (212 °F) or, in the presence of certain catalysts, at room temperatures Although it resembles oxygen in many respects, ozone is much more reactive; hence, it is an extremely powerful oxidizing
- Explainer: What Is Ozone Pollution? | Earth. Org
Ozone (O3) is a colourless gas that is formed naturally in the atmosphere, and is made up of three oxygen atoms bound together Ozone gas can be used as bleach or disinfectant, and a sterilising agent for air and drinking water due to its strong oxidative property that kills microorganisms
- What Is Ozone? Definition and Facts - Science Notes and Projects
Even though the ozone layer only contains a low concentration of the molecule, it is enough for absorbing harmful solar ultraviolet radiation The combination of O2 and O3 entirely screens harmful UV-C and most UV-B Some UV-B and nearly all UV-A reaches the Earth’s surface
- Ozone (O₃) - Definition, Structure, Preparation, Uses . . . - Examples
InChI=1 O3 c1-3-2: EU Number: 233-069-2: Gmelin Number: 1101: RTECS Number: RS8225000: Uses of Ozone(O₃) In the Atmosphere Protects from UV Rays: The ozone layer in the Earth’s stratosphere acts as a shield, absorbing and blocking the majority of the sun’s harmful ultraviolet radiation This protection reduces the risk of skin cancer and
