Heat & Temperature - Coggle Diagram
Heat & Temperature
sources of heat
things that produce heat
eg: sun,light bulb
definition of temperature
measurement of how hot or cold something is
measured by:
clinical thermometer
laboratory thermometer
heat
cannot be seen but can be felt
heat flow
from a hotter region to a colder region
effects of heat gain & heat loss
heat gain
rise in temperature
expansion in matter
implications:
rollers under the bridge
changes in state
heat loss
fall in temperature
contraction in matter
implications:
air spaces in liquid containers
changes in state
good conductors & poor conductor of heat
good conductor
allow heat to be transferred through it easily
eg: Iron, Steel, Copper, Aluminium
poor conductor
does not allow heat to pass through it easily
eg: air, water, rubber, plastic
definition of heat
amount of heat in a matter that makes it hot
