Question

PLEASEE HELP ME! How much heat is required to change 32.5 grams of liquid water into steam, from room temperature (25°C) to 115°C?

formulas given:
ΔH fusion = 334 J/g
ΔH vaporization = 2259 J/g
Q = mcΔTwhen increasing the temperature within a single phase.
Q = mΔH when passing through a phase change.

Answer 1

I hope this helps I take chemistry too

Step-by-step explanation:

The formula I used is ΔH vaporization = 2259 J/g, ΔH vaporization is the symbol for the molar heat of vaporization. This value is a constant for a given substance.Remember that the water is being condensed. The molar heat of vaporization value is used at the solid-liquid phase change, (boiling or condensing).
