Answer:
A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes.The second change of phase is boiling, as the temperature stays the same during the transition to gas.
Explanation:
A neutral solution has a pH of: 7
Answer choice B.
With a process called Fission. This generates heat to produce steam.
This energy required is the latent heat, which is required for physical transformations. Specifically, when it involves changing liquid to gas, this latent heat is called the heat of vaporization. The formula is:
Q = mΔHvap
The molar mass of the compound is
Q = (48.7 g)(31.6 kJ/mol)(1 mol/84.93 g)
<em>Q = 18.12 kJ</em>
