Overview
Thermal properties of matter describe how heat, temperature, and matter interact. Temperature measures hotness, while heat is energy transferred because of a temperature difference. Matter expands on heating, stores heat differently according to its nature, changes state at fixed temperatures under
Key Concepts
Heat is the form of energy
Heat is the form of energy transferred between systems or between a system and its surroundings because of temperature difference. Temperature is a re
The ice point and steam point
The ice point and steam point of water are fixed points used for calibration. On the Celsius scale these are 0 °C and 100 °C, and on the Fahrenheit sc
The Kelvin scale begins at absolute
The Kelvin scale begins at absolute zero, which is -273.15 °C. The relation is T = t_c + 273.15. For a low-density gas, PV = μRT. Boyle's law gives PV
Most substances expand on heating
Most substances expand on heating. Linear expansion is given by Δl/l = α_lΔT, volume expansion by α_v = (ΔV/V)(1/ΔT), and for an ideal gas at constant
Water contracts on heating between 0
Water contracts on heating between 0 °C and 4 °C and has maximum density at 4 °C. This is why lakes and ponds freeze at the top first.
Learning Objectives
- Understand the difference between heat and temperature.
- Learn how temperature is measured using fixed points and scales.
- Use the ideal gas equation and absolute temperature scale.
- Describe thermal expansion in solids, liquids, and gases.
- Apply specific heat capacity, calorimetry, and latent heat ideas to numerical problems.
