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.
