Heat 2 Science
Study Guide
| There are three ways in which | |
|---|---|
| There are three ways in which heat moves from place to place. | Radiation, Conduction and Convection |
| Heat is transferred through space in waves | Radiation |
| Heat move through the collisions of particles | Conduction |
| Heated liquids or gases move in currents | Convection |
| The TOTAL energy of all the particles in a substance | Thermal |
| A measure of the average kinetic energy of the particles in an object. | Temperature |
| The water in a bathtub and in a cup is at the same temp. The water in the bath has more because it has more water molecules. | Heat |
| Heat, like work, is measured in units called | Joules |
| Heat moves only from objects to objects. | hot to cold |
| The amount of energy needed to raise the temperature of 1kg of something 1degreeK. | Specific heat |
| Water has a higher specific heat than land. Therefore, will heat up quicker. | Land |
| The handle of a spoon in a bowl of soup becomes warm due to heat transfer by the process of | Conduction |
| Stars transfer heat through this process | Radiation |
| Three best insulators are | Vacuum, Paper, Cotton |
| Three best conductors are | Aluminum, Silver, Iron |
| Fiberglass is a common . | Insulator |
| This is a material that slows the transfer of heat | Insulator |
| Most substances, like liquid in a thermometer acts like this when heated. | Expands |
| There are four states of matter | Solid, liquid, gas and plasma |
| The temperature at which a solid changes into a liquid is called the | Melting point |
| Water boils at this temperature C, F or K | 100C, 212F, 373.16K |
| Water freezes at this temperature C, F or K | 0C, 32F, 273.16K |
| The temperature at which all motion of particles stops is called | Absolute Zero |
| Absolute zero = ________K __________C | 0 Kelvin -273 Celcius |
