SCI 2233: Heat and Temperature Definitions

Temperature

A measure of the average kinetic energy of particles in a substance.

Thermometer

An instrument that uses the physical properties of materials to determine temperature accurately.

Heat

The transfer of energy due to temperature differences. The meaning of positive or negative signs in heat transfer problems

Internal Energy

The total energy (kinetic + potential) within a system

Units of Heat

Specific Heat Capacity

The amount of heat required to raise the
temperature of 1g of a substance by 1°C.

Latent Heat

The energy required for a phase change without changing temperature.

Phases of Matter

Solid, liquid, gas, plasma, and their transitions for
example: melting, freezing, etc

Types of Heat Transfer

Conduction, convection, and radiation.

Laws of Thermodynamics

Principles governing the relationship between heat, work, and energy, including the conservation of energy and entropy.

Properties of Water

Boiling, point, freezing point, density, specific
heat capacity
