The  number  of calories  that are required to increase  the temperature of 13 g of ethanol  from 11c to 23 c is =92.04 Cal

     calculation

 This is calculated Q(heat)= MCΔT   formula  where
Q(heat)=?
M(mass)= 13g
C(specific heat capacity)=0.59 cal/g/c
Δ T(change in temperature)=23-11= 12 c

Q  is therefore = 13g x 0.59 cal/g/c  x12 c= 92.04 Cal
