A heat bath is an idealized system with an infinite heat capacity, capable of absorbing or providing finite amounts of heat without changing its own temperature. It is commonly used in statistical mechanics to model the interaction of a system with its environment, facilitating the study of thermal equilibrium and energy exchange processes.

Statistical mechanics is a branch of physics that uses probability theory to study and predict the behavior of systems with a large number of particles, bridging the microscopic laws of physics with macroscopic observations. It provides the framework for understanding thermodynamic properties and phase transitions by averaging over the possible states of a system rather than tracking individual particles.

The environment encompasses all living and non-living things occurring naturally, interacting as a complex system that sustains life on Earth. It is crucial for providing resources, regulating climate, and supporting biodiversity, making its preservation vital for future generations.

Thermal equilibrium is a state in which two or more objects in thermal contact no longer exchange energy through heat, resulting in a uniform temperature across the system. It is a fundamental concept in thermodynamics that underlies the zeroth law, which allows the definition of temperature scales.
