What method of heat transfer is used when cooking a baked potato in the microwave?
When heat is transferred by microwaves, that is called radiant heat transfer.
Which combination of fundamental units can be used to express energy?
Kgxm2/s2
What heat transfer is being used when a heat lamp is heating a box?
conduction
What are the unit used to express heat?
"Heat", as used in physics, refers to heat energy - and the unit for any type of energy is the joule.
What is ntu in thermodynamics?
NTU is nothing but Number of Transfer Units. It is one of the method used to find the heat transfer of hot and cold body it is applicable to both parallel and counter flow.============The NTU Method is used to calculate the rate of heat transfer in heat exchangers when there is insufficient information to calculate the Log-Mean Temperature Difference (LMTD). If fluid inlet and outlet temperatures are specified or can be determined by simple energy balance, the LMTD method should be used; but when these temperatures are not available The NTU or The Effectiveness method is used. It is based off of the maximum possible heat exchange in an infinitely long heat exchanger. From this, different heat exchangers can be compared and estimates of actual heat exchange calculated based on the NTU effectiveness.
Why are coolants used in nuclear power industries?
To transfer the heat produced in the fuel to the steam raising units.
Where in the house is a heat pump used?
A heat pump is often used in air conditioning units and refrigerators because a heat pump is used to transfer heat from one place to another. Often heat pumps are used to remove heat from a building
What Units used to express energy transfer?
Its the exact amount without loosing any in the process. This process is called "The Law of Conservation of Energy".
What units are used to express distance?
metre
What is heat conductor used for?
Its used to transfer heat into electrical signal
What units are used to express energy and work?
joules
What do conduction and convection have in common?
They're both modes of heat transfer via material media.
What is a radiator used for?
To transfer heat.

cubic or cubed
Which are units used to express volume?
liter and cubic centimeter
Which are the units used to express volume?
