How are heat and work similar and different?
Both heat and work are forms of energy transfer between systems. However, heat transfer occurs due to a temperature difference and is a non-mechanical process, while work transfer requires a force acting over a distance and is a mechanical process.
What is capacity to do work or transfer heat?
That would be energy. Energy is the ability of a system to do work or transfer heat.
Which thermodynamic process takes place when work is done on the system but no energy is transferred to or from the system as heat?
The thermodynamic process that takes place when work is done on the system but no energy is transferred as heat is an isochoric process, also known as an isovolumetric or constant volume process. In an isochoric process, the volume of the system remains constant, so there is no heat transfer, and all the work done goes into changing the internal energy of the system.
How do heat transfer fluid systems work?
Heat transfer fluid systems work by circulating a fluid (such as oil or water) through a closed loop system to transfer heat from one area to another. The fluid absorbs heat at the source, such as a heater or solar panel, and then moves to a heat exchanger where it releases the heat to the desired location, such as a room or water tank. The process is continuous and controlled to maintain a stable temperature.
what are the three types of heat transfer and how do they work?
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves.

Why work and heat transfer are not property of the system?
irstly from Thermodynamics point of view, we need to call heat as Heat transfer. Both Heat and work transfer are energies in transit. They come into picture only when a process is taking place. Also the quantity of heat transfer depends on the type of process or path followed. So Heat Transfer is a path function but not a property(which is a point function). 📷 In case of properties, the difference in properties (here P2-P1 or V2- V1)between state 1 and state 2 always remains same irrespective of the path followed. So properties are called Exact Differentials or Point functions. But in case of Heat transfer and Work transfer, the quantity of heat and work transfer between state 1 and state 2 depends on the path followed. Therefore heat and work transfer are not exact differentials,they are Inexact differentials or path functions.

How do the three types of heat transfer work together to to heat the troposphere?
three types of heat transfer work together to heat the troposphere by heating the solid with (conduction) air ( convection) and radiation from the sun.

What are the functions of the heat?
The main purpose of a heat sink is to expel heat from a generating source. Heat sinks work through the process of conductive and convection heat transfer. Heat sinks are a passive form of cooling, as they have no moving parts and require no power.
what are the three types of heat transfer and how do they work?
The three types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through direct contact of particles. Convection is the transfer of heat through the movement of fluids or gases. Radiation is the transfer of heat through electromagnetic waves.
What is an adiabatic process?
An adiabatic process is one in which there is no heat transfer into or out of the system. This means that any change in internal energy of the system is solely due to work done on or by the system. Adiabatic processes are often rapid and can lead to changes in temperature and pressure without heat exchange.
How does Convection always work more quickly than conduction?
Convection involves the movement of fluid particles, which can transfer heat more efficiently than the direct contact of particles in conduction. In convection, the fluid transports heat by circulating, allowing for a faster transfer of thermal energy compared to the slower process of heat transfer in conduction through stationary particles.
