The relationship between heat and temperature, latent heat and specific heat capacity, and the laws of thermodynamics are covered in this unit. It is recommended that excessive emphasis on mathematical relationships be avoided. This is particularly true in the section on thermodynamics, which should be treated descriptively in the Secondary Level Physics program. The main focus throughout the unit should be on a descriptive development of kinetic molecular theory, and on performing investigations which provide a basis for understanding calorimetry.
The difference between heat energy and temperature is confusing
for some students. This needs to be developed and reinforced
carefully in the unit
.
In this unit students will increase their abilities to:
Demonstrate an understanding of the kinetic molecular theory.
Explain how theories are used in science.
Perform experiments to investigate heat energy.
Develop an enthusiastic pursuit of learning as a life-long endeavour.
Recognize the need to control variables in experiments.
Demonstrate the need for precision in measurement and careful observation in experiments.
Recognize that both qualitative and quantitative analysis of data have important roles in scientific investigations.
Demonstrate respect for the environment and for all forms of life.
Use a wide range of possibilities for developing knowledge of the major concepts within physics. (COM)
Develop understanding of the uses and abuses of mathematical concepts in everyday life. (NUM)
Promote both intuitive, imaginative thought and the ability to evaluate ideas, processes, experiences and objects in meaningful contexts. (CCT)
Develop a contemporary view of technology. (TL)
Support students in treating themselves and others with respect. (PSVS)
Access information. (IL)
