Learning  Objective: Recall  facts pertaining  to  the  development  of gases  and  the  characteristics  of gases. 5-1. 5-2 Pneumatic  power  is  most  commonly used in complex systems. 1. True 2. False Which  of  the  following characteristics  is/are  true  for gases? 1. They  have  no  definite  volume 2. They have no definite shape 3. Gases are lighter than equal volumes of liquids 4. All of the above Learning Objective: Relate the common  temperature  scales  by converting  temperature  readings between them. 5-7. Which  of  the  follownig  statements is  true  concerning  absolute  zero? 1. 2. 3. 4. It is the temperature at which no heat remains in a gas    but not the lowest temperature  obtainable It was attained only once, at which  time  the  absolute  zero point  of  -273.16°C  was determined It is the temperature at which  all  molecular  activity in a substance ceases It is the temperature to which  liquids,  solids,  and gases can be reduced and at which  most  molecular  activity ceases IN  ANSWERING  QUESTIONS  1-8  THROUGH  5-12 REFER TO FIGURE 11-1 IN YOUR TEXTBOOK. 5-8.
