HalpPlease:
does anyone know latent heat fusion formula's and specific latent heat etc. and also what are all the ways of improving experiments.

Thanks :D

Ghost Of Highbury:
specific heat capacity =

specifc latent heat =

the expirmental changes can be

-repeat for average and accuracy
-insulate
-switch of power source when recording readings to prevent heating of the wire and change in resistance
-use data logging for accurate time intervals
-transfer hot objects into beakers of water more quickly to prevent heat loss
-check for zero error- (vernier calliper & screq gauge)
-read measurements perpendicularly to scale-avoid parallax
-use a lid (to avoid heat loss)




if i get more i'll add them here

dlehddud:
yea the formulas right
and the accuracy problems differ with each question
it depends wot topic the questions on

yea..those were the general ones/.

if u know more..cud u plz add on..

dlehddud:
transfer hot objects in to beakers of water more quickly to prevent heat loss
check for zero error- measurements start at zero
read measurements perpendicularly to scale-avoid parallax
use a lid - seperate mark from insulate

nd looking 4 more  :D :D
