1
Energy that is made up small particles, called atoms & molecules; the faster the movement of particles the warmer it becomes; this is what kind of energy? THERMAL ENERGY
2
LIGHT (ELECTROMAGNETIC OR
Energy that travels in waves such as visible light, ultraviolet radiation, microwaves & infrared radiation are called what? LIGHT (ELECTROMAGNETIC OR RADIANT) ENERGY
3
Energy stored in the nucleus of a atom & released during nuclear reactions is called what?
NUCLEAR ENERGY
4
Three Temperature Scales
Fahrenheit Celsius Kelvin Water Boils 212° 100° 373 K Body Temperature 98.6° 37° 310 K Room Temperature 68° 20° 293 K Water Freezes 32° 0° 273 K
5
An increase in the size of a substance in response to an increase in the temperature of the substance is known as what? THERMAL EXPANSION
6
The temperature at which molecules stop moving (0 on the Kelvin scale)
ABSOLUTE ZERO
7
Lesson 2: What is Heat? The movement of thermal energy from an area of higher temperature to an area of lower temperatures
8
The transfer of energy as heat through material is known as what?
THERMAL CONDUCTION
10
A material through which energy can be transferred as heat is what?
THERMAL CONDUCTOR METALS (COPPER & IRON)
11
A material that reduces or prevents the transfer of heat is called what?
THERMAL INSULATOR
13
The transfer of thermal energy by the movement of the particles from one part of a material to another is called what? CONVECTION
14
What is the transfer of thermal energy by collisions between particles in matter?
CONDUCTION The transfer of thermal energy by electromagnetic waves is called what? RADIATION
16
The quantity of heat required to raise a unit mass of homogeneous material (the same) 1 K or 1°C in a specified way given constant pressure & volume is what? SPECIFIC HEAT (MELTING POINT)
17
Lesson 3: Matter & Heat The states of matter are the physical forms in which a substance can exist. They are Solids, Liquids or Gases.
18
(Examples include: freezing, melting, boiling & condensing)
The change of a substance from one physical state to another is called? A CHANGE IN STATE (Examples include: freezing, melting, boiling & condensing)
19
The change in state from a solid to a liquid is called what
The change in state from a solid to a liquid is called what? The change of a state from a liquid to a solid is called what? “I’M MELTING!” MELTING FREEZING
