唔係latent咩??

specific latent heat of a substance is the energy transferred
by heating to change the state of 1KG of substance without
a change in temperature.
即係 latent heat for 1 kg 0既substane

Specific latent heat is the latent heat per unit mass of a substance. It is a physical property of material that makes up an object. For example, when an object of mass m changes from solid to liquid, the latent heat absorbed is E=ml where l is the specific latent heat of fusion of the substance.

姐係唔係咁:
好似水咁
由冰變水個過程
放出既就係latent heat
溫度係不變
Specific latent heat 就係個種substance(1 kg) 變態個陣放出既
e=ml

specific heat capacity 就係:
一種substance (1 kg) 升一度temp 所要既e?
e=mc T

咁點解一定要放d野出來

同埋點解temperature不變

change state既時候咪不變囉

由0既水--->0既冰

所需既energy只係change state 既時侯

所以咪不變囉

睇書應該幾易明,...不過"ｓｐｅｃｉｆｉｃ　ｌｅｔｅｎｔ　ｈｅａｔ"唔係會考課程黎o架咩???

中3咪開始讀會考lor

latent heat真係好難明

乜而加咁早就讀定o架??好似以前d小六讀中一咁...

洗唔洗呀,你估一定讀理科架咩

唔怪得而加d人咁多『壓力』!

我覺得lenses 仲難明

所以
讀文科個d 人
都放棄哂phy chem bio e 3科
