Calorimetry

• The specific heat capacity is the amount of energy needed to raise one gram of a substance by one degree Celsius.
• The specific heat capacity is the amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
• Specific latent heat of fusion (J/g) = Energy required to melt one gram of solid at its melting point
• Specific latent heats are used when there is no change in temperature during a reaction, such as melting or boiling.
• Heat capacity is measured in joules per degree Celsius (J/°C) or kilojoules per degree Celsius (kJ/°C).
• Specific latent heat of vaporization (J/g) = Energy required to evaporate one gram of liquid at its boiling point
• Specific latent heat is the amount of energy required to change the state of one mole of a substance without changing its temperature.
• Latent heat of fusion is the amount of energy required to melt or freeze one kilogram of a solid at its melting point, with no change in temperature.
• Latent heat of sublimation (J/g) = Energy required to convert one gram of solid directly into gas without passing through the liquid state
• Latent heat is measured in joules per mole (J/mol), kilojoules per mole (kJ/mol), or calories per mole (cal/mol).
