Question

Using the formula qmetal = m × c × ΔT, calculate the specific heat of the metal. Use the data from your experiment for the metal in your calculation.

Answer 1

@thushananth01 would I be solving for ΔT here?

Answer 2

@Somy can you help me? :3

Answer 3

nope, you need to find specific heat capacity here

Answer 4

how would I do that?

Answer 5

alright

Answer 6

could you write all the info from pic ?

Answer 7

Yeah; the measured mass of the metal is 27.776 g, distilled water is 26 mL, distilled water temperature is 25.3 c, temperature of metal is 100.6 c, temperature of the mixture is 38.9 c

Answer 8

alright look
when it comes to formula
Q= mc Delta T

only values you care about are about water

Answer 9

in this case i mean

Answer 10

so distilled water is 26 mL, distilled water temperature is 25.3 c

Answer 11

yes and temp of mixture?

Answer 12

38.9 c

Answer 13

do consider this one because that metal is with water
and because metal had some temperature which raised waters temp after putting it water

Answer 14

so now we actually will find Q

Answer 15

Specific heat capacity of water is 4.18

Answer 16

would I set it up like this:
\[q= 26 * 4.18 (38.9 - 25.3)\]

Answer 17

yeah

Answer 18

and q is 1442?

Answer 19

no, its close but u made mistake in some number

Answer 20

it'll be 1478.048

Answer 21

or we can say 1478 J

Answer 22

where did I make the mistake?

Answer 23

never mind I checked my calculations

Answer 24

ok) now lets move on

Answer 25

now we have value for Q
and now we are going to consider metal

Answer 26

what is metal's mass? and Delta T

Answer 27

ok so it would be

q= 27.776 x 4.18 x (100.6 - 38.9) ??

Answer 28

no no specific hear capacity is what we need to find

Answer 29

Q is what we found in the other part

Answer 30

heat*

Answer 31

oh okay so we use q that we found ok sorry

Answer 32

1478 J = 27.776* X* (100.6-38.9)

Answer 33

yes thats right :) because the question is asking for specific heat capacity of metal

Answer 34

is it clear?

Answer 35

yes! i'm doing the calculations now

Answer 36

good :))

Answer 37

i got 1.16? :x

Answer 38

let me check if something is wrong with my calculator ok?

Answer 39

i did 1713 by 1478 instead of 1478 by 1713

Answer 40

no no

Answer 41

it should be 1478/1713

Answer 42

ok then sorry its .8628

Answer 43

yeah :)

Answer 44

thank you so much you're the best!

Answer 45

hehe you are welcome :))♥♥♥
