Coal releases carbon dioxide when burned. The reaction looks like this:
C(s)+O₂(g)→CO₂(g)
I hope this helps. Let me know in the comments if anything is unclear.
The amount of heat that is required to melt 22g piece of ice at -8 degrees to water at 14 degrees is 1,011.56 Joules.
<h3>How do we calculate the required heat?</h3>
Required amount of heat will be calculated by using the below equation as:
Q = mcΔT, where
m = mass = 22g
c = specific heat of ice = 2.09 J/g. degree C
ΔT = change in temperature = 14 - (-8) = 22 degree C
On putting all values, we get
Q = (22)(2.09)(22) = 1,011.56 J
Hence required amount of heat is 1,011.56 J.

The options a and b are correct
Explanation:
This options provided to the question are the answers to the question. But for clarification. When the fat melts, the change of state that occurs here is from solid to liquid (which is called melting) while the change of state that occurs when the water evaporated is from liquid to gas (which is called evaporation).
