|
Heat is a type of energy called? |
Thermal energy. |
|
|
What is the specific heat capacity of a material? |
The amount ofenergy required to raise 1kg of the material by 1 °C. |
|
|
What is the equation to find out howmuch energy is needed to raise the temperature of a material? |
Energy=mass*specific heat capacity *temperature change. |
|
|
How does conduction work? |
Conduction works by transferring heat from one molecule to another by vibrating through a substance, |
|
|
What is kinetic energy? |
It means that the free electrons move faster and transfer the energy through themetal. |
|
|
Why don't insulators conduct heat? |
They don't have free electrons and so they do not conduct heat . |
|
|
What method of heat transfer occurs mainly in solids? |
conduction |
|
|
Which states of matter are fluids? |
Liquids |
|
|
What method of heat transfer can occur in a vacuum? |
Radiation is the only method of heat transfer that does not require particles . |
|
|
What method of heat transfer occurs when particles with a lot of energy take the place of those with less? |
Convection because when particles with a lot of energy they take the place of those with less. |
|
|
What method of heat transfer do we see in our weather patterns? |
We see convection currents (and so heat transfer by convection) in our weather patterns. |
|
|
What surfaces best absorb infrared radiation? |
Black |
|
|
What surfaces best emit infrared radiation? |
Black |
|
|
What method of heat transfer explains why hot air balloons rise? |
Hot air balloons rise because of convection. |
|
|
Which part of the human body loses the most heat? |
The head. |
|
|
What different ways can thermal energy be transferred. |
Conduction Convection Radiation |
|
|
The transfer of kinetic energy between particles using vibrations or free electrons is called |
Conduction |
|
|
what do we call the transfer of heat when a liquid or gas gets heated and expands, causing a change in density therefore a flow of fluid. |
Convection |
|
|
The transfer of heat using infrared electromagnetic waves is called |
Radiation |
