The energy transferred in joules is calculated using the below formula
Q(heat energy) = M(mass) x C (specific heat capacity ) x delta T(change in temperature
delta T = 0. 0c- 14 c = -14 c
M= 29.5 g
C of water is always = 4.18 j/g/c
= 29.5 g x -14 c x 4.18 j/g/c =-1726.34 joules are needed when 29.5 g of liquid water decrease from 14 c to 0.0 C
