HEAT N' THERMODYNAMICS
KEEP IN MEMORY ........:
mercury thermometers wid cylindrical bulb r more sensitive than those wid spherical bulb.
alcohal thermometers r preffered over clinical thermometers due 2 larger value of d coefficient of cubical xpansion .
at d followin tempt. different temp scales hav d same reading:@fahreinheit & reaumur
-25.6 F = -25.6 R
@reaumur & celcius
0 R =0C
@celcius & fahreinheit
-40 C = -40 F
@fahreinheit & kelvin
574.25F = 574.25 K
@celcius & kelvin cannot hav same readin at any temp
six temp measure minimum & maximum temp durin a day it uses mercury as well as alcohol as thermometric substance
d rankine is d smallest temp range amomg all d scales of temp
water has negative coefficient of volume expansion for temp range (0 C - 4C)
d heat capacity or thermal capacity depend's on d nature of d substance ( specific heat capacity)and d mass of quantity of matter of d body
in d case of meltin and boilin poin temp do not change only internal potential energy of system changes
hydrometer is d branch of thermal physics that deals wid d meaasurements of d amount of water vapour in atmosphere
hope u'll find it useful..............
i knw these points r a mixture
frm different topics
but i felt them 2 b jotted down 2gether
do rate if u like it ......
n waitin anxiously 4 ur comments ......
