Heat is the transfer of energy d one part to another of a body or between bodies k temperaturas.El are at different heat is energy in transit and always flows from hotter bodies smaller alos
temperature: the quantity that tells us so hot and so cold qe is an object in comparison with a reference
celsius: esl international unit most used to haunt ordinary qe
Fahrenheit: The temperature unit is proposed by Gabriel Fahrenheit, which is fixed at zero to one hundred i congelacioni temperatures evaporation of ammonium chloride water
kelvinIt is the temperature unit scale established by William Thomson, on the basis of degree Celsius, absolute zero point set keeping the same dimension i
kcal
joule
lime
Driving: the way of propagation of heat otrava a solid body due to the clash between their molecules
Convection: characterized pork is produced through a k fluid transports heat between areas with different temperatures
radiation: the propagation of heat through electromagnetic waves k spread, even in the vacuum
dilatation: volume change in length or some other metric dimension k undergoes a physical body temperature due wing
linear expansion: is the increase or decrease of length k undergoes a solid with increasing temperature
linear expansion coefficient: the incrmento d k has a rod length d dterminada substance, with an initial length of a meter, when its temperature rises one degree Celsius
dilated superficial expancion or contraction is linear in 2 dimensions
cubic expansion: it involves a change in the dimensions of a body: lengthwise, width and height, the cubic expansion differs from the linear dilatation pork also implies an increase in volume
cubic expansion coefficient: the volume k incrmento Xperimenta a body given substance d d equal volume to unity, to raise its temperature 1 ° c
specific heat: d a substance is equal heat capacity C d wing the substance of its mass
heat released and absorbed: in any heat exchange made, heat is transferred to iwal absorbed in other words heat lost = heat gained
