Question

NEED HELP ASAP PLEASE!!

Answer 1

1 g requires 80 cal of heat, then 100 g requires 80*100=8000 cal

1 cal = 4.1868 J

Then Q = 1910.767 J

for you:

The heat energy is defined from the equation:

$Q=mC$Δ$T$

where

• Q: the heat energy in (Joules).
• m: the mass of the material which is heated in (kg).
• C: the specific heat capacity in (J/kg.K).
• Δ$T$: the change in the temperature in (K)
