In raised objects |
|
|
|
Where is chemical energy stored? |
In muscles, food, batteries and fuel |
|
|
|
When is sound energy released? |
By vibrating objects |
|
|
|
Where is electrical energy stored? |
In moving charges or static electric charges |
|
|
|
Where is elastic potential energy stored? |
In stretched or squashed objects |
|
|
|
Where is nuclear energy stored? |
In the nuclei of atoms |
|
|
|
What is specific heat capacity? |
The specific heat capacity of a substance is the amount of energy needed to change the temperature of 1 kg of the substance by 1°C. |
|
|
|
What is conduction? |
Conduction is the process where vibrating particles transfer energy to neighbouring particles. |
|
|
|
In which state does conduction mainly occur? |
In solids |
|
|
|
What is convection? |
Convection is where energetic particles move away from hotter to cooler regions. |
|
|
|
In which states does convection usually occur? |
Liquids and gases |
|
|
|
What reduces the rate of energy transfer by heating? |
Insulation - You can have thick walls made from a material with low thermal conductivity and you can have thermal insulation: •Cavity walls with an air gap between two walls to reduce the amount of energy transferred by conduction through the walls •Loft insulation •Double glazed windows •Draught excluders around doors and windows to reduce energy transfers by convection |
