- Ideal Gas
- The particles have no internal structure, are indestructible, do not interact with each other except when they collide, and all collisions are elastic.
- Ideal Gas Constant
- Also known as Molar Gas Constant.
- Ideal Gas Law
- Gases obey the gas laws at low pressures and at temperatures above those at which they liquefy.
- Ideal Solution
- All molecules interact in exactly the same way; the solvent-solvent, solvent-solute, and solute-solute intermolecular forces are all equivalent.
- Idempotent Law
- Combining a quantity with itself either by logical addition or logical multiplication will result in a logical sum or product that is the equivalent of the quantity.
- Identity
- A number that when an operation is applied to a given number yields that given number. For multiplication, the identity is one and for addition the identity is zero.

- States that any expression is equal to itself.
- Idle
- Internal combustion engine operating at no load and minimum engine speed.
- Idler Frequency
- In a parametric amplifier, the difference between the input signal and the pump
signal frequency.
- Idler Gear
- An idler gear may be used between two gears so that the direction of rotation on the two shafts is in the same direction.
