Important Topics for Halliday Resnick and Walker Fundamentals of Physics Volume 1 Solutions Chapter 18: Temperature, Heat and The First Law of Thermodynamics
Thermometer and Temperature
The thermometer is the device that helps us to measure temperature. Temperature is basically an NSI based quantity which will help to identify hot and cold. Thermometer contains a working substance with a measurable property like length or pressure. In the chapter, you will know how thermometers work.
Zeroth Law of Dynamics
Whenever a thermometer any other object cone in contact with each other they reach a stage of thermal equilibrium. You will then take the reading of the thermometer which will help you to identify the temperature of the other object. The process provides you with consistent temperature measurement. These measurements are because of the zeroth law of dynamics.
The Kelvin Temperature Scale
The kelvin temperature scale is also from the SI system which is based on the triple point of water, 273.16K. In the chapter, you will know the connection between the temperature and kelvin.
Celsius Fahrenheit Scales
In the chapter, you will know about these two types of scales with their equations.
All the objects change their size with the changes in their temperature. In the chapter, you will know the change in linear dimension with the change in temperature.
Heat is the energy that transfers between the system and the environment because there is a temperature difference between them. Heat can be measured in joules, calories, kilo calories or British thermal units.
Heat of Transformation
You know that matter can exist in three forms that are solid, liquid and vapour. The heat that a material absorbs can change the stage of the material for example: solid to liquid or liquid to gas. Thus the amount of energy required per unit mass in order to change the state of a particular material is known as the heat of transformation. Also in the chapter, you will know about the heat of evaporation and heat of fusion.
Other Topics Discussed in the chapter
- Work associated with volume change: that gas can easily exchange energy with its surrounding by doing some work. In the chapter, you will know how to calculate the amount of work done to change the state.
- First law of thermodynamics: mainly the principle of conservation of energy for a thermodynamic process is known as the first law of thermodynamics.
- Applications of the first law: the first law of thermodynamics will help you to understand the applications in different cases like adiabatic process, constant volume process, cyclical process, free expansion.
