Did you use ms1∆T1=ms2∆T2
Final temp of both metal and water is 18.3°C btw
i did like
heat of metal and then heat of water initally
and then put that equal to mixture heat
Nahi nahi just equate heat transferred
Mass toh same hi hai
I don't know what you mean by equal to mixture heat
If you don't mind explaining
Mines coming out to be 0.24
Heat cap
Seems very less...
soo like the heat we gave the metal to raise its temp to 75 first that heat and then the heat we gave to water to take it to 15 and the heat that the mix holds at last equating that
tht is the ans
This i did
Don't consider the heat you gave to the metal, assume it is already at 75°C
Similarly with the water, these are pre-determined conditions
Always remember this: heat given out is heat taken, until the temperatures are equal
par pehle ye method worked
in other ques
Could you send one such q
The problem is we don't know starting from which temperature they are heating right
Maante hain they heated metal to 75°, but what was the starting temp of the metal
A 5.00-g sample of aluminum pellets (specific heat capacity 5
0.89 J/8C ? g) and a 10.00-g sample of iron pellets (specific
heat capacity 5 0.45 J/8C ? g) are heated to 100.08C. The
mixture of hot iron and aluminum is then dropped into
97.3 g water at 22.08C. Calculate the final temperature of the
metal and water mixture, assuming no heat loss to the
surroundings
0
But it's not given right
Lemme read
yh ik but this worked last times
Accha dekhta hu
Heat to 100° right, not sure what is the 8 doing
61
So acc to you first we will find how much heat is gone in heating the metals to 100°, then how much heat to raise water to 22°
How will you do that total mixture thing
The equation
If we do equate ms∆T of one obj to total heat in the mixture, we'll assume all that heat went into one particular object, if it makes sense

35:00 is an explanation
Calorimetry ke 14 qs hain 2 min vids concepts clear ho jayenge
I guess I’m late to this discussion but still likh diya chalo lol
Is tarah se socho
Heat kyun flow hoti hai?
Temperature difference right?
To kab rukegi? Temperature same ho Gaya tab
Tab Tak jitni energy hot body lose karegi
Utni hi cold body gain kar legi
yahi to lagake maine kiya
to baki me aaraha
lekin is wale me nhi ara
Yahi lagana hota hai
did u look at this one
There might be some calc error
Bheji konsa hai galat aa raha hai jo
I’ll see ruko
i did that one (61st) like this
and 63rd also like that
and this method worked here
yh this is what i did
Fir conceptual error nahi hai
Something is up with calculations
Calculator se kar ke dekho sab
aaa vapis try karti hu
Is baar hath se mat karo
lmao usi se karti hu mostly
☠️
Galat baat hai yaar
Prep ke time nahi use karna chahiye calc 😭
hnn vo kal ikdam man nhi tha
isiliye
varna usually nhi jati hu calc tak
BAs thik hai fir to
Mujhe to ab dekho thodi bohot calc ke liye bhi lagta hai
Mera man nahi karta bilkul
0.18 aara ......
...uhmmm @Varun_Arora
Ye vo aluminium vala hai
hain?
oh
hain?
mera to 0.24 aara
aur ans hai 0.25
Temperature poocha tha na?
Water se kam kaise ho jayega 😭
Final temperature poocha hai na usme to
ok ok mai confuse ho gyi
Sabse first vaale ka 0.244 hai
Specific heat vaale ka
dusre question se
Usko 0.25 likha hai book ne
Koi ni lol
isme mera 23.9 aaya
3-4 que ik sath me yahi hota hai
upr se mera chasma
Sahi hai vo dw
Bohott Gandi calc hai
Calculator me bhi itna time lag gaya
I was double checking each time
maine is se khrb log kiye hai
dimag me smh
pagal ho gyi hu
Damn
Tbh
Mujhe calc karna bohot faaltu lagta hai 😭
fr
Exams me calculator hona chahiye allowed
Agar ban chuka hai
To kyun na use karein?!
and konsi lab me mujhe bolenge chalo log nikalo
bro vo bhi calc use karte hai
Vahi to
walter jaise teacher tak use karte calc itna
Chalo mai chala abhi
63rd ka batao na equation yahi gadbad hora
Lab ka kaam aa gaya
ok okkk
Thodi der me pakka
hnhnn
Heyy
@Sephrina
63 vala I just saw
Upar usi ka to solution diya tha na?
.....
ye na
par mere tarike me kaha gadbad hori hai?
Ek sec dekhta hun
hn
Tumne use kya kiya?
Thoda describe karo
Usme samajh nahi aa raha
pehle jo heat metal ko mili phir jo water me thi
aur phir end jo heat thi mix me
tumhe mixture ki specific heat capacity kaise pata hai?
3 variable ho gaye na fir to
paani ki use ki maine isiliye glt hai?
Better would be
Mixture ki specific heat capacity paani vaali nahi hogi
Nope
ohhh
ok phir hn
Al or water dono ka net effect aayega
thik got it
hn
Only thing to remember
In thermal
Heat lost by hot body = Heat gained by cold body
okk
