A thermos bottle has a shiny interior What type of heat transfer does it prevent?
It prevents heat loss through radiation.It prevents heat loss through radiation.It prevents heat loss through radiation.It prevents heat loss through radiation.
What is heat absorption and loss?
heat gain is when an object get hotter. heat loss is when an object gets colder.
Is melting heat gain or heat loss?
Heat gain, otherwise, a heat loss would be like turning off the heat beneath a saucepan on the stove.
Why a hair dryer has a high- heat setting with a lower resistance than the low-heat setting?
Because a higher resistance would have resulted in more heat loss, but the higher is he current, the more energy is lost to heat. Therefore, a lower resistance would release more heat.AnswerPower is equal to voltage squared divided by resistance. So, for a given voltage, the lower the resistance the higherthe power.
What is the difference between heat gain and heat loss?
These are exact opposities - heat gain is an increase in energy that results in an increased temperature of the material. Heat loss is a loss in energy that results in a decreased temperature of the material.
What are two affects of resistance?
Heat & power loss.
How could having foam walls be good for the environment?
They reduce heat loss through the walls, hence you need less fuel (directly or at the power-station) to heat the building and maintain the temperature for a given heat rise and time.
Is evaporation heat gain or heat loss?
For what?It requires a heat gain for the water,but a heat loss for whatever the water is in contact with.
Why does coffee stay hot longer in a shiny pot?
because it absorbs the heat given off by the coffee reducing heat loss.
What are the effects of a severe heat wave?
A severe heat wave can cause dehydration, loss of appetite, Power outages etc...
Is precipitation heat loss or heat gain?
heat loss
What is copper loss?
Copper loss is the term often given to heat produced by electrical currents in the conductors of transformer windings, or other electrical devices
Which transistor is used for high speed power application?
In transistor the heat is created during transition stage means from cutoff to saturation and reverse, so if transistor used for high frequency application power loss can be minimized. The heat produced during switching is actually power loss.
Where does power loss goes?
since energy must be conserved, we know that the power is not actually lost, just converted. The loss youre reffering to would almost always be in the form of heat.
What is the heat of electricity?
Amount of electrical energy converted to heat energy when current flows through a conducting material.According to Joule's Law, quantity of heat energy dissipated is given by,Q=i2Rtnotein power transmission, aluminum wires* are used to reduce the heat energy lossusing a step up transformer,we increase the voltage and reduced in current to reduce heat loss.(heat loss is proportional to the square of current.)* though silver is the material with minimum resistance,it is too dear to be used as transmission wires.
A power loss occurs when you apply carburetor heat because?
The flow of air in the carburetor venturi is restricted.
A thermos bottle has a shiny interior What type of heat transfer does it prevent?
It prevents heat loss through radiation.It prevents heat loss through radiation.It prevents heat loss through radiation.It prevents heat loss through radiation.
