Heat Transfer and Thermometric Properties

Your feet feel warmer when you step onto a rug from an adjacent tile floor because the rug



 
Which of the following methods of heat transfer involves the actual physical movement of high temperature molecules to regions of lower temperature?
 
If one's hands are being warmed by holding them to one side of a flame, the dominate form of heat transfer is which of these processes?
 
The higher the temperature of a black-body radiator, the

 
When two objects are in thermal equilibrium,



 
When a bimetallic bar made of brass and iron strips is heated, the band bends towards the iron strip. The reason for this is




 
Compared to a giant iceberg, a hot cup of tea has



 
Heat flows from an object with a high


 
If 25 g of hot water are added to 35 g of cold water, the heat lost by the hot water is ___ the heat gained by the cold water.
 
The first law of thermodynamics is a restatement of the



 
As the Kelvin temperature of a body increases, the total internal energy of the body
 
Temperature is proportional to the ____ in a substance.



 
If only the potential energy of the molecules in a body is increased, the absolute temperature of the substance
 
Consider a piece of copper at 22 ºC. If its internal energy is directly proportional to its absolute temperature in Kelvin, what final temperature would be needed to have a new internal energy equal to three times its original value?
 
A copper rod has one end of its ends placed in a bunsen burner's flame and the other end is embedded in an ice block. By what factor is the rate of heat flow changed when the rod length is tripled?
 
A copper rod has one end of its ends placed in a bunsen burner's flame and the other end is embedded in an ice block. By what factor is the rate of heat flow changed when the rod's radius is tripled?
 
If the absolute temperature of a spherical object were tripled, by what factor would the rate of radiated energy emitted from its surface be changed?
 
If the inside and outside temperatures remain the same but the surface area of a window pane is doubled, then the amount of heat conducted through the window will
 
Place equal masses of aluminum and copper the same distance from a fire. If aluminum has a higher specific heat than copper, the one to undergo the fastest increase in temperature will be the
 
Heat is added at a constant rate to a sample of pure substance that is initially a solid at temperature To. The temperature of the sample as a function of time is shown in the graph below.



From the graph, one can conclude that the
