Question

How much heat will be absorbed by a 66.3 g

Answer 1

Q=mcΔt

Q=66.3 x 0.93 x (67-23)

Q=2712.996 J

Answer 2

$\quad \huge \quad \quad \boxed{ \tt \:Answer }$

$\qquad \tt \rightarrow \:Q = 2.713 \:\:kJ$

____________________________________

$\large \tt Solution \: :$

$\qquad \tt \rightarrow \: Q = ms\Delta T$

$\textsf{Q = heat evolved/absorbed = ??}$

$\textsf{m = mass in gram = 66.3 g}$

$\textsf{s = specific heat = 0.930 J/g °C}$

$\textsf{ΔT = change in temp = 67 - 23 =44°C}$

$\large\textsf{Find Q : }$

$\qquad \tt \rightarrow \:Q=( 66.3) \sdot (0.93) \sdot(44)$

$\qquad \tt \rightarrow \:Q = 2713 \: \: joules$

$\qquad \tt \rightarrow \:Q= 2.713 \: \: kj$
