LAB 1 OBJECTIVES: • To acquire an operational definition of temperature and to understand the connection between temperature and thermal equilibrium. • To understand how the temperature of a body changes as it undergoes thermal interactions with its surroundings. • To understand the difference between the quantity of heat energy transferred to or from an object and its temperature.
A 40 kg timber wolf uses approximately 19,000 kJ of energy during the course of a day. A komodo dragon, a reptilian predator of the same size, uses only 2,100 kJ. Explain why this is using the concepts covered in this lab.
