The question asks to complete the definition of an open system in thermodynamics. An open system is characterized by its interaction with the surroundings, specifically regarding the transfer of matter and energy.
B) Exchange of Energy — An open system allows for the exchange of both matter and energy with its surroundings. Examples include a boiling pot of water (exchanges water vapor and heat) or a living organism (exchanges food, waste, and heat).
The question asks to complete the definition of a closed system in thermodynamics. A closed system is characterized by its interaction with the surroundings regarding matter and energy exchange.
Correct Option: A) Exchange of Energy is Possible
The question asks for an example of an isolated system. An isolated system is a thermodynamic system that cannot exchange either energy or matter with its surroundings. We need to identify which of the given options best fits this definition.
D) Thermos Flask — A thermos flask is designed to minimize both heat transfer and mass transfer with the surroundings. It has a vacuum between its double walls to prevent heat transfer by conduction and convection, and its reflective surfaces reduce heat transfer by radiation. It is also sealed to prevent the exchange of matter. Therefore, it is the best practical example of an isolated system among the given choices.
What is the full form of (P)(V)(T ) of the system?
(i)Pressure Volume Temperature
(ii)Pete Versus Toby
(iii)Primary Validation Test
The question asks for the full form of (P)(V)(T) in the context of a system. This abbreviation is commonly used in thermodynamics and physics to refer to fundamental properties of a system.
Option (i) "Pressure Volume Temperature" correctly identifies the full forms of P, V, and T as they are universally understood in scientific and engineering contexts, especially when discussing the state of a system (e.g., in the ideal gas law, \(PV = nRT\)).
The question asks for the term that describes a system based on its measurable or macroscopic properties. This is a fundamental concept in thermodynamics.
Correct Option: C) State of a Thermodynamic System — The state of a thermodynamic system is defined by its measurable, macroscopic properties such as pressure, temperature, volume, and composition. These properties describe the bulk characteristics of the system.
The question asks for the term used to describe measurable or macroscopic properties. This relates to the classification of properties in thermodynamics and physical chemistry.
D) Bulk Properties — Bulk properties are those that describe the overall behavior of a large amount of matter, which are directly measurable or observable at a macroscopic level. This aligns perfectly with the definition of measurable or macroscopic properties.
