How does transient heat transfer differ from steady state heat transfer?
In transient heat transfer, the rate of heat transfer is changing with time. By definition, in steady-state heat transfer, the rate of heat transfer does NOT change with time. In the real world, heat transfer starts out as transient and then approaches steady-state with time until the difference between the actual and the ideal becomes negligible or until thermal equilibrium is approached.
Does heat transfer mean the same as heat transformation?
heat transfer is when heat from one object transfers to another. Heat transformation is when you have enough heat or cold to change the state of an object (ice to water).
Which state of matter is least likely to transfer heat by convection?
Solid state because the particles are unable to circulate. Liquid and gas both transfer by convection.
What is the difference between steady state and unsteady conduction?
good
Heat can be transfered by conduction or convection?
By both way. Conduction is the basic of heat transfer, the energy (heat) is transfer from molecule to molecule from different in temperature gradient. Concept of convection is when there is motion of molecule come to concern like wind blow and take away the heat rapidly. Convection heat transfer can only occur in fluid state e.g. liquid and gas. In solid, only conduction heat transfer taken place.

What is convective heat transfer?
Convection heat transfer is the transfer of heat by the movement of a fluid.

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.
What is the difference between steady state and unsteady conduction?
good
What is the study of heat transfer during chemical reactions and changes of state is?
Thermodynamics
State one way of reducing heat transfer by draught?
Using draught
What are two examples of heat transfer?
Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
What is delirium in a sentence?
He was in a delirium state of mind. It means a very disturbed and unsteady state of mind.
