Among several things in the room, the thing which has lower temperature than room temperature.
Answer to Problem 29A
None
Explanation of Solution
Introduction:
Temperature of the body defines the kinetic energy of the molecules which comprise the body.
In the room, table, chair, and persons are there. Among these things none has the temperature lower than the room temperature.
Conclusion:
Therefore, among the several mentioned things, nothing inside the room has temperature lower than room temperature.
Among several things in the room, the thing which has greater temperature than room temperature.
Answer to Problem 29A
The temperature of the people inside the room has temperature greater than the room temperature.
Explanation of Solution
Introduction:
Temperature of the body defines the kinetic energy of the molecules which comprise the body.
When the temperature of the body increases, molecules inside the body starts vibrating. Temperature measures the amount of thermal energy contained in the system.
Conclusion:
Therefore, the temperature of the people inside the room has temperature greater than room temperature.
(c)
Among several things in the room, the thing which has the temperature equal to room temperature.
(c)
Answer to Problem 29A
The temperature of the table, chair has temperature equal to the room temperature.
Explanation of Solution
Introduction:
Temperature of the body defines the kinetic energy of the molecules which comprise the body.
Suppose room contain the chair and table. These materials are made up of insulator. These materials are the bad conductor of heat. Since these material does not allow to pass heat through them so, the temperature of table and chair is same as the temperature of the room.
Conclusion:
Therefore, the temperature of chair, table inside the room has temperature equal to room temperature.
