Heat And Temperature Flashcards
What is the definition of Convection?
Circular movemenr of a fluid due to temperature differences within fluid
Definition of Radiators
Slow the movement of the enery form the particles of another substance
Definition of thermal energy?
The average particle motion heat, temperature of a substance
Definition of radiation
Made of waves of different sizes
Reflexr or absorb when hitting different materials
All radiation travels at 300 000 km/s
What is Geothermal energy?
Harvesting thermal energy from volcanic activity underground. Usually used to produce electricity and hot water.
What is solar energy?
Harvesting radiant energy from the sun, to create electricity and thermal energy. Can be passive of active collectors.
What is Passive Solar Heating?
A low technology version of capturing solar radiation. Using absorptive material (black or dark) to capture heat thermal energy in some way.
Definition of active solar heating
Harvestinf solar radiation using complex technology such as solar panels, batteries, and electrical gas.
Non renewable recources
Like fossil fuels
Name all of these fossil fuels
Crude oil, coal, natural gas, and byproducts of crude oil such as plastics.
Definition of electromagnetic radiation
Another word for radiation electromagnetic radiation.
Definition of thermal energy
Thermal energy is a measurement of the average motion of particles in a substance measure by temperature.
Definition of heat
The measure of the average particle
motion of a substance, the average
thermal energy of particles in a substance,
and it measured using a device capable of
measuring temperature. Most importantly
heat is the process of thermal energy
transfer from hot to cold particles.
Definition of temperature
The measure of the average particle motion
of a substance, the average thermal energy
of particles in a substance, and it measured
using a device capable of measuring
temperature.
The particle model of matter
Definition 1 All matter are made of tiny particles 2. Those particles are always in motion 3. There is always space between particles
