What is Specific Heat capacity?
The amount of thermal enery that warms or cools a specific part of an objest by 1'C
What is radiation?
Radiation is the transfer of energy without any movemnt of matter( no particles)
What is Passive solar heating?
uses the materials in a structure to absorb, store, and release solar enrgy.

What is a boiling/ meltign stage?
when a substance reaches certain temperatures
What is thermal conduction?
is teh transfer of thermal energy through direct collisions between particles.
What is Cogeneration?

Name 4 devices that can resord temperture.
Thermocouple, Bimetallic Strip, Recording thermometer, Infrared Radiation
What is Thermal energy?
The energy generated by the movement or vibration pf particles
energy assosiated with hot objects
What is evaporative cooling?
when at the surface of a droplet of liquid, some of teh particles are able to escape into the air, as high energy particles escape the average energy of teh remainig particles is less ans so the liquid cools.
How many features of enrgy systems are there?
5
When is carbon monoxide produced?
When fire burns without enough oxygen.
