Question

what does the k represent in the newtons law of cooling? @Data_LG2 @Catch.me

Answer 1

I think k is some kind of constant (specific heat capacity). Different objects have different values for k. But I'm not really sure. I forgot my physics now :/

Answer 2

or the cooling rate o.o

oh boy i messed up, sorry

Answer 3

Thanks, but do you have an idea what the constant represents? I was thinking the weight of the object being frozen or cooled but I'm not sure. .-.

Answer 4

oh since you said specific heat capacity would it maybe be the specific cooling capacity or the specific frozen capacity?

Answer 5

I don't think it's the weight. I'm thinking that it's only concerned about the surface of the materials.

for your question, i really don't know. i'm confused too.
maybe i'll try to revise my chemistry later -.-

Answer 6

Alright, thanks anyway.

Answer 7

sorry

Answer 8

No, its fine really.

Answer 9

ok but if you need help in mathematics or physics you can tag me ^_^

Answer 10

Will do :)

Answer 11

@aliboo997
r = h A/C.
h is the heat transfer coefficient (assumed independent of T here).
A is the surface area of the heat being transferred.
C is the heat capacity.

Answer 12

I was talking about the cooling law, but thanks anyway. & sorry for such a late respond.
