Heat of fusion (? hfus) is used for calculations involving a phase change between solid and liquid, with no temperature change. for h2o, ? hfus=6.02 kj/mol. specific heat capacity (c) is used for calculations that involve a temperature change, but no phase change. for liquid water, c=4.184 j/(g? ? c).heat of vaporization (? hvap) is used for calculations involving a phase change between liquid and gas, with no temperature change. for h2o, ? hvap=40.7 kj/mol. part ahow much heat is required to raise the temperature of 92.0g of water from its melting point to its boiling point? express your answer numerically in kilojoules.

q = 38,5 kJ

Explanation:

In its melting point, at 0°C, water is liquid. The boiling point of water is 100°C. It is possible to estimate the heat you required to raise the temperature of water from 0°C to 100°C using:

q = C×m×ΔT

Where C is specific heat of water (4,184J/g°C), m is mass of water (92,0g) and ΔT is change in temperature (100°C-0°C = 100°C)

Replacing:

q = 4,184J/g°C×92,0g×100°C

q = 38493 J, in kilojoules:

q = 38,5 kJ

I hope it helps!

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.
