well, you must have a object that gets put under pressure by pistons or what not.
For a molecule to absorb infrared radiation, it must have a change in its dipole moment when it vibrates. This means that the molecule must have different charges distributed unevenly within it, causing it to interact with the infrared radiation and absorb its energy.
For a collision between reactant molecules to be effective in producing new chemical species, they must have enough kinetic energy to overcome the activation energy barrier, and they must collide in the correct orientation to break and form chemical bonds.
Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew. That's the first requirement ... the weather conditions: Liquid water droplets in the air. But that doesn't guarantee a rainbow. Here's what else you need: -- The sun, shining in a clear sky, standing less than 42 degrees above the horizon, behind you. If more than 42 degrees high, none of a rainbow can be above the horizon. -- From where your head is, the clear sun and the watery air must be in exactly opposite directions.
An aqueous solution is considered neutral when it has a pH of 7, indicating an equal concentration of hydrogen ions (H+) and hydroxide ions (OH-) in the solution. This balance ensures that the solution is neither acidic nor basic.
For a substance or solution to exhibit electrolyte behavior, it must be composed of ions that can move freely in the solution and the substance must be able to conduct electricity when dissolved in a solvent.

For a rigid body to be in equilibrium, two conditions must be met: the sum of all external forces acting on the body must be zero, and the sum of all external torques acting on the body must also be zero.
In this context, "and" is used to indicate that both conditions must be met, while "or" is used to indicate that only one of the conditions needs to be met.
For a spontaneous process to occur, the conditions must involve an increase in entropy and a decrease in free energy.
A series of conditions must be met to affect an output condition.
they must be in the same circle or congruent circles they must have the same central angle measure
