Final answer:
Temperature is a measure of the average kinetic energy of particles in matter, indicating hotness or coldness. Changes in temperature can affect chemical reactions and the viability of enzymes.
Step-by-step explanation:
Temperature is a measure of the average kinetic energy of the particles in matter. It indicates a measure of how hot or cold an object is. For example, when a substance changes from solid to liquid, it is because there was an increase in the temperature of the material. Chemical reactions usually proceed faster if the temperature is increased.
Enzymes are unstable materials in biology that can be viable longer at lower temperatures. Temperature is an important parameter in chemistry and biology.
