Expert Solution

Specific heat capacity : Specific heat capacity of any substance is defined as the amount of heat required (or to be added to the substance) to raise the temperature of 1 g of the substance by 1 degree (C or K). its units are J/g (⁰C or K).

State function : State functions are functions whose value depend only upon the initial and final state of the system and are independant of the path followed to reach the final state. For example, temperature, volume, mass etc.

Standard State : Standard state of any substance is used as a reference in chemistry to measure different properties of that substance in different conditions. It is taken differently for different substances for eg for gases,standard state is the state it would have as a pure substance obeying the ideal gas equation at 1 bar pressure.

Enthalpy change: When any chemical reaction takes place in constant pressure (isobaric) conditions, the heat involved (added or released) is known as enthalapy. It can be calculated as difference in enthalapy of products and reactants. Units are kJ/mole.

Heat: Heat is a form of energy which passes between a system and its surroundings apart from the energy transferred between them by doing work or by transfer of matter. Its units are joules (J) or calories.

Temperature: Temperature is defined as a measure of hotness or coldness of any substance. Its units are Kelvin or degree celsius.

The standard enthalpy of fusion of water is 6.01 kJ/ mol, the molar heat capacity at a constant pressure of liquid water can be assumed to be constant at 75.5 J/mol*K, thoughout the liquid phase, and the standard enthalpy of vapoziration is 40.7 kJ/mol at the boiling point. Calculate the total entropy change (in SI units), for heating one mole of water, starting with ice just below the melting point and going to just above the boiling point at standard...

Heat Capacity Learning Goal: To understand the concepts of heat capacity, specific heat, and molar heat capacity. Heat capacity, C, is the amount of energy required to raise the temperature of a substance by exactly 1 degree Celsius. The energy needed to warm an object increases as the mass of that object increases. We see this in our everyday life. For example, we know that it takes much more energy to heat a large tank of water than a small...
