Ch-08: Thermal Properties of Matter

Ch-08: Thermal Properties of Matter 

After studying this unit, the students will be able to:

• Define temperature (as quantity which determines the direction of flow of thermal energy).
• Define heat (as the energy transferred resulting from the temperature difference between two objects).
• List basic thermometric properties for a material to construct a thermometer.
• Convert the temperature from one scale to another
• Describe rise in temperature of a body in terms of an increase in its internal energy.
• Define the terms heat capacity and specific heat capacity.
• Describe heat of fusion and heat of vaporization.
• Describe experiments to determine heat of fusion and heat of vaporization of ice and water respectively by sketching temperature-time graph on heating ice.
• Explain the process of evaporation and the difference between boiling and evaporation.
• Explain that evaporation causes cooling.
• List the factors which influence surface evaporation.
• Describe qualitatively the thermal expansion of solids.
• Explain thermal expansion of liquids.
• Solve numerical problems based on the mathematical relations learnt in this unit.
