The heat required to raise the temperature of 69.0 g of water from its melting point to its boiling point is 28.842 kJ
Heat is defined as the amount of energy transferred from a system to its surroundings due to a temperature difference.
The relationship between heat, mass, and temperature is given by
[tex]q = mc \Delta T[/tex]
Where q = heat required to the raise the temperature
m = mass of water
c = specific heat capacity
∆T = change in temperature
The melting point of water, Initial temperature [tex]T_i[/tex] = 0°C
The boiling point of water, Final temperature [tex]T_f[/tex] = 100°C
[tex]\Delta T = T_f - T_i[/tex]= 100 - 0 = 100°C
Substitute into formula, m = 69 g, c = 4.18 J/g°C, ∆T = 100°C
q = 69 × 4.18 × 100 = 28842 J = 28.842 kJ
Thus, The heat required to raise the temperature of 69.0 g of water from its melting point to its boiling point is 28.842 kJ
