• Behavior of atoms and particles on microscopic scales

• Behavior of chemical reactions

Who introduced the uncertainty principle in 1927?

• Albert Einstein

• Niels Bohr

What does the uncertainty principle state about measuring a particle's properties?

• Velocity can be measured precisely, but not position

• Position can be measured precisely, but not velocity

• Both position and velocity can be measured precisely

• There is a limit to how precisely both position and velocity can be measured simultaneously

What is a Bose-Einstein condensate?

• A state of matter with high energy

• A state of matter with low density and high temperature

• A state of matter formed at temperatures close to absolute zero

• A state of matter with high viscosity
