The heat energy from the fire is transferred to the pot by
- <em>radiation</em> — the hot coals radiate heat to the pot.
- <em>convection</em> — the hot gases from the fire travel upward until they reach the pot
The pot absorbs the heat energy and <em>conducts</em> the heat to the water inside.
The hot water <em>conducts</em> heat to the peas in three steps:
- warming the frozen ice and peas to 0 °C.
- thawing the ice and peas at 0 °C.
- heating the peas to 100 °C and cooking them at that temperature.
<em>Note</em>: Heat always flows spontaneously from a hotter to a cooler object.
Not sure but i think c Particles that struck the edges.

Answer: The name of this Hydrate is magnesium sulphate monohydrate.
Explanation:
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
a) If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of = 87.0 g
Mass of = 13.0 g
Step 1 : convert given masses into moles
Moles of =
Moles of =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For =
For =
Hence the empirical formula is
Thus the name is magnesium sulphate monohydrate.
