Thermal properties of matter describe how matter behaves when heat is transferred or temperature changes. Temperature decides the direction of heat flow, while heat is energy transferred because of a temperature difference. Matter expands on heating, with solids showing linear, superficial, and volu
Key Concepts
Temperature is the physical quantity
Temperature is the physical quantity that indicates how hot or cold a body is. Heat is energy transferred between two bodies or between a system and i
Thermometry is the branch of physics
Thermometry is the branch of physics that deals with the measurement of temperature. A thermometer uses a thermometric property such as mercury length
The Celsius scale uses 0°C
The Celsius scale uses 0°C for the ice-point and 100°C for the steam-point. The Fahrenheit scale uses 32°F and 212°F as the same fixed points. The Kel
The Celsius and Fahrenheit scales
The Celsius and Fahrenheit scales are related by C/5 = (F-32)/9. This relation is derived from the fixed points of the two scales.
Boyle's law states that PV =
Boyle's law states that PV = constant at constant temperature. Charles' law states that at constant pressure, the volume of a gas is directly proporti
