chmvijay · Answer

to increase one degree u need 2.4 J/g-C
but you have temperature difference of 16 u have to increase then the energy released is 
=2.4*16 =X  find X 
since its per gram of material
but u have 193 gram so
it will be =2.4*16*193= X *193 gram= Y ur answer

@abb0t following chmvijays instructions I now have 38.4*193=7,411.2
I thought I was suppose to use the formula Q=m C delta T
I am so confused please break it down

abb0t · Answer

yes, you should be using $Q=mc\Delta T$

anonymous · Answer

ok so Q=heat

 m=mass (in grams) C=specific heat
T= the change in temperature 
right?

abb0t · Answer

yes.

anonymous · Answer

Q=?
m=193g
C=2.4 J/g*C
T=19-35C
whats Q?
and did I fill this out right?
