Question

Any help is appreciated :)
equations Q=mcΔT and Q=ml
pic attached

Answer 1

Like i know the equations \[Q=mc \Delta T \] and \[Q=ml \] but idk how to find what goes where

Answer 2

For # 10 so far I got m=143g

Answer 3

You have everything you need m = mass c is a constant and deltaT is the change in temp.

Answer 4

Q is the heat solve for Q

Answer 5

oh ok cool that helps! :)

Answer 6

c is not 20 and deltaT is not 45

Answer 7

ohhh :(

Answer 8

c is the specific heat for water do you know what that is?

Answer 9

no :/

Answer 10

c = 4.184 J/gC

Answer 11

deltaT is the change in temp so final - initial

Answer 12

calor específico del agua es cantidad de calor que hay que suministrar a la unidad de masa de una sustancia para elevar su temperatura en un grado , en el agua el calor especifico es aproximadamente 1 cal/g°C

Answer 13

so
m=143
c=4.184
Δt=25

Answer 14

yep

Answer 15

so q= 14,957.8

Answer 16

q is in joules

Answer 17

oh lol 14,957.8 joules

Answer 18

Thank u! :)

Answer 19
