Chapter 16 Temperature and Heat Q.1CQ

Answers to odd-numbered Conceptual Questions can be found in the back of the book A cup of hot coffee is placed on the table Is it ¡n thermal equilibrium? What condition determines when the coffee is in equilibrium?

Solution:

A body is said to be in thermal equilibrium, if there is no exchange of heat between the body and its surroundings

The moment a coffee cup is placed on the table, its temperature is different from that of its surrounding atmosphere. Hence, there is a transformation of heat energy from the coffee cup to the surroundings Therefore, the coffee is not in thermal equilibrium Over time, the temperature of the coffee will decrease until it is the same as the room temperature At this point, it will be in equilibrium, as long as the room stays at the same temperature

Chapter 16 Temperature and Heat Q.1P

The official record for the lowest temperature ever recorded on Earth was set at Vostok, Antarctica, on July 21, 1983. The temperature on that day fell to —89.2°C, well below the temperature of dry ice. What is this temperaturein degrees Fahrenheit?
