knp bila kita sejuk, sentuh air kita rasa panas suam?

michiru_iko

salam sumer..

Pernah x korang sumer alami keadaan ini? apabila korang sedang dlm keadaan sejuk tetapi bila korang sentuh atau berendam dlm air korang rase suam2 kuku (for sure air yg sy mention bukan air panas tp air paip biasa.) tlg explain pada yang tahu

khaieza86

SALAM...
mmg la klu kite sjuk then g toilet air yg kite rase 2 suam....
sbb air 2 bertindak balas ngan haba tgn kite yg sejuk bangat 2...
air 2 bertindak untuk nuteral kan blik haba yg hilang akibat kesejukkan 2.......

secretsmile81

nie soklan jenis ape nie? macam tak patut tanya je......

khaieza86

cik newbie....
michiru_iko just tny jer sbb nak tambah ilmu pengetahuan...
so klu u rasa u xnak tolong die bg jawapan better u xpyh sent anything k...
sori klu i terkasar....

syaiful

betul3...
dgn nada ipin

that's what we called "keseimbangan terma" - ni kena rujuk fizik form 4 ...tang topik topik  haba pendam .. semua tu lah ....

kita rasa sejuk tapi sentuh ayaq kita rasa panas meaning your body absorb haba dari ayaq tu sebab tu ayaq tu rasa panas...

tapi bila kita demam , bil asentuh aayaq rasa sejuk , kan? so haba tu mengalir kat mana?

hehe....sila jawab

good question though

well ..when people ask..sayang...

kita  just answer dulu ...rasanya kita put aside nilai bad or not .....

tapi what we could do is to paraphrase or rephrase cara tanya

a.ceCCo

aku selalu perasan time mandi sungai pagi2 buta (kat camp)
bila masuk je kaki dalam sungai tu mak aii   sejuk gilerr
tapi bila dah rendam seluruh baddan and stay still - tak bergerak sambil peluk tubuh - tiba2 rasa suam

michiru_iko

ooo fizik form 4 dulu x kasi contoh nie tp contoh lain

tp thanks a lot for the info its help a lot

mbhcsf

i juast wanna know

in what way does it helpful to you?

so, kita still dalam tajuk yg sama

apa jadi kalau kita letak Voltmeter kat  satu bikar yg berisi ayaq panas and satu beaker lagi ayaq sejuk / atau ais ker ..?


apa jadi ?

think about the process....

what is obvious ?

ni semua kat physics form 4.....

michiru_iko

it help me understand why it happen everyday

awak nie macm cikgu fizik je

dalam perinsip keseimbangan yang lebih akan mengalir ke yg kurang. dari segi epistemology akan ada perinsip entropy dan negentropy.
dalam kehidupan sebenar ramai merasakan bahawa diri kita berhubung secara linear tetapi sebenarnya tidak. tetapi dalam bentuk circular. kesan akibat dan kesan begitula seterusnya.

sama macam air tadi keseimbangan adalah perlu supaya yang satu tidak lebih dari yang lain .


err korang faham ke ni?

teringat kat soklan neraka tu exothermic ker endothermic....

bila disebut term entropy    -  it does ring a bell somewhere  and  has something to do with thermodynamics ? law  but  negentropy ? - ni i never heard before.
This can be very interesting when you try to  see it from epistemological POV.
Cares to elaborate, please?

hmm? macam mana tu? i kurang jelas the basis of the question?

exothermic buang haba
endo serap haba?

neraka - hell fire -- fire serap ker buang ?
hmm?

why do you ask thsi question is more  interesting actually

mbhcsf

saya plain Jane jer bukan cikgu pun....tak dapat jadi cikgu

no, it's not my Q...just something that i read, don't know whether it's true or totally fabricated (since there are a few versions of it across the web, different professor, different uni), but surely it's funny as hell...pardon the pun eh?

here's the kopipes...

Hell from an engineering approach         

The following is an actual question given on a University of Washington engineering mid term. The answer was so profound that the Professor shared it with colleagues, which is why we now have the pleasure of enjoying it as well.

Bonus Question: Is Hell exothermic (gives off heat) or Endothermic (absorbs heat)?

Most of the students wrote proofs of their beliefs using Boyle's Law, (gas cools off when it expands and heats up when it is compressed) or some variant. One student, however, wrote the following:   

"First, we need to know how the mass of Hell is changing in time. So we need to know the rate that souls are moving into Hell and the rate they are leaving. I think that we can safely assume that once a soul gets to Hell, it will not leave. Therefore, no souls are leaving. As for how many souls are entering Hell, let's look at the different religions that exist in the world today.

Some of these religions state that if you are not a member of their religion, you will go to Hell. Since there are more than one of these religions and since people do not belong to more than one religion, we can project that all souls go to Hell. With birth  and death rates as they are, we can expect the number of souls in Hell to increase exponentially.

Now, we look at the rate of change of the volume in Hell because Boyle's Law states that in order for the temperature and pressure in Hell to stay the same, the volume of Hell has to expand as souls are added. This gives two possibilities:

1. If Hell is expanding at a slower rate than the rate at which souls enter Hell, then the temperature and pressure in Hell will increase until all Hell breaks loose.
2. Of course, if Hell is expanding at a rate faster than the increase of souls in Hell, then the temperature and pressure will drop until Hell freezes over.

So which is it? If we accept the postulate given to me by Teresa Banyan during my Freshman year, "...that it will be a cold day in Hell before I sleep with you." and take into account the fact that I still have not succeeded in having sexual relations with her, then, #2 cannot be true, and thus I am sure that Hell is exothermic and will not freeze."

This student received the only A.

well, i wonder whether the student is married or not....? Caucasian , eh? Kokesen ...
good lah  it's really clever ..i like the reasoning minus the fact yg kita punya system nilai lahkan...

u rasa soalan kita  kalau bukan exactly   tanya pepasal hell or heaven  , u rasa dapat  capai tahap macam tu ker?

michiru_iko

wah...my topic are expanding...

bnyak tul genius kat sini ea...

mbhcsf

okay you nak extend the concept of keseimbangan?
tapikan pernah terfikir tak ( i dunno you ni sapa  tapi tak pa ) apa apa pun dalam dunia ni mesti akan patuhi konsep / apa ni merujuk kepada proses bilogi . fizik , chemistry  mesti fenomena fenomena ni nak capai steady state?

napa u  rasa?
