A student using this technique finds that when putting a hot piece of metal into a calorimeter which contains 35.070g of water,

the water temperature increases from 22.4 c to 24.7
c. how much heat (q) was absorbed by the water (s.h of water = 4.184 j/g k)

Q=cmΔt,

c=<span>4.184 j/(g*⁰C)
m=35.070 g
</span>Δt=t(final)-t(initial) = 24.7-22.4=2.3⁰C
<span>
Q=4.184</span> j/(g*⁰C)* 35.070 g * 2.3⁰C ≈ 337.49 J ≈ 338 J
