Question

NEED HELP ASAP PLEASE!!

How much heat would be required to melt 100g of ice?(1g requires 80 cal of heat) show your work...

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)
