Study Notes
Thermal Expansion
- The term for the relative expansion divided by the change in temperature is called the coefficient of thermal expansion.
- As the energy in particles increases, the intermolecular forces between them decrease.
- Materials that contract on heating within certain temperature ranges are known as anomalous expanders.
Water's Thermal Expansion
- The coefficient of thermal expansion of water drops to zero at a temperature of 4°C.
Temperature and Kinetic Energy
- The relationship between temperature and the average molecular kinetic energy of a substance is that as temperature increases, kinetic energy also increases.
Expanding Expressions
- The fundamental concept in mathematics that involves simplifying algebraic expressions by multiplying out brackets is called expanding expressions or algebraic expansion.
- Expanding expressions allows us to simplify expressions and solve complex problems in various areas of mathematics, science, and engineering.
- In finance, expanding expressions is used to calculate interest rates, loan payments, and investment returns.
- The property of expanding expressions involves combining like terms and simplifying equations.
- Computer science uses expanding expressions to develop algorithms and solve computational problems.
Test your knowledge of the basic principles of thermal expansion and its effects on the properties of matter in response to temperature changes.
