Referencing the figure to the left, how much energy in J would be needed to change 59 g of ice at -22.75 °C into steam at 128.65 °C

Important numbers/equations:
q = Cpm: AT
Specific Heat of Water (liquid) = 4.18 J/go°C
Specific Heat of Water (solid) = 2.06 J/g•°C
Specific Heat of Water (gas) = 2.01 J/g °C

Molar Heat of Fusion of water: 6009 J/mol
Molar Heat of Vaporization for water: 40790 J/mol

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
