Question

F. Defines:

1. Ignition temperature

2. Fermentation

3. Thermosetting plastics​

Answer 1

Explanation:

1.The ignition temperature of a substance is the least temperature at which the substance starts combustion. Substances which spontaneously ignite in a normal atmosphere at naturally ambient temperatures are termed pyrophoric.

2.the chemical breakdown of a substance by bacteria, yeasts, or other microorganisms, typically involving effervescence and the giving off of heat.

"the fermentation of organic matter by microorganisms in the gut"

3.thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.

hope helpful!?

♡Ignition temperature ➡️ The autoignition temperature or kindling point of a substance is the lowest temperature in which it spontaneously ignites in a normal atmosphere without an external source of ignition, such as a flame or spark. This temperature is required to supply the activation energy needed for combustion.

♡Fermentation ➡️ Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen.

♡Thermosetting plastics ➡️ A thermosetting polymer, resin, or plastic, often called a thermoset, is a polymer that is irreversibly hardened by curing from a soft solid or viscous liquid prepolymer or resin. Curing is induced by heat or suitable radiation and may be promoted by high pressure, or mixing with a catalyst.
