Heat is one form of energy, and a quantity of heat
can be described in any unit of energy.
-- joule
-- foot-pound
-- watt-second
-- calorie
-- Calorie
-- BTU
-- erg
-- kilowatt-hour
-- newton-meter
Note:
"Degrees" are units of temperature, not heat.

There is Celsius, the Metric way to measure heat, which is based on the boiling and cooling of water, with 0 degrees being the freezing point of water, and 100 degrees being the boiling point. There is Kelvin, which is the same thing as Celsius, except 0 degrees Kelvin is absolute zero, or the coldest and object can possibly be. Finally, there is Rankine, which is the same thing as Fahrenheit, except 0 degrees equals absolute zero. Fahrenheit is most commonly used in America, and Celsius is most commonly used everywhere else.

What is the chemical term for heat transfer in a reaction?
it is called energy transfer or calories transfer
Heat transfer between two substances that are in contact is called what?
CONDUCTION
Which type of heat transfer occurs in a pot of water when less dense heated water rises to the water's surface and displaces the more dense cooler water at the top causing the cooler water to sink to?
The heat transfer is by conduction.
What is heat condution?
Conduction of heat:Conduction of heat is when heat energy flows through an insulator/Conductor.
How do you measure conduction of heat?
Heat, as distinct from temperature, can only be measured using a medium, ie a substance of known specific heat. Then by measuring its temperature the amount of heat can be calculated. Water is the easiest to use, at least up to its boiling point, and by definition, a rise of 1 deg C per gram of water is 1 calorie. One of the most frequent needs to measure heat is in power stations or industrial processes which use water or steam. If you are working out heat flow using steam you have to use steam tables which are calculated giving the heat content per unit mass of steam at various pressures and temperatures. Sometimes you would need to measure heat flows in other fluids, such as at an oil refinery, then you would have to know the specific heat (that is the heat per degree of temperature) of the fluid being handled.
Why do geologists measure soil temperatures?
Because soil temperatures indicate the heat transfer process occurring at the earth's surface.
What is overall surface efficiency of fins?
it is ratio of the total heat transfer from the surface area associated with both the fins and exposed portion of the base to maximum heat transfer from same surface area (in ideal conditions we get maximum heat transfer)
What type of heat transfer called when molten rock below the Earth's surface rises then cools and sinks below the surface again?
Convection.
How does vasodiliation increase heat transfer to environment?
It increases the surface area of blood that is exposed to the environment, which means there is a greater heat transfer capacity - meaning heat transfer is increased.
What is the heat from below earth's surface called?
Heat from inside the Earth is called geothermal heat.
How can light be transfer to heat?
Light striking and being absorbed by a surface is converted to heat.
What is heat transfer through direct contact called?
The transfer of heat through direct contact is called conduction.
Body heat tranferred to the air by what?
The body transfer heat to air by a heat transfer method called radiation.
How does heat absorbed by earth's surface transfer back into the atmosphere?
Heat transfer more specifically convection. That is what makes wind. No sun no wind
What is the transfer of heat called?
Convection
What is the transfer of heat energy through empty space called?
The transfer of heat energy through empty space is called radiation.
How fast does 4oz of water freeze?
Freezing rate depends on the surface area, the heat transfer medium, and its temperature. If it is a thin layer (large surface area) of water it would freeze faster than a thick layer (smaller surface area). A liquid heat transfer medium, like liquid nitrogen, would have a higher heat transfer rate than a gas, like air. Lastly, the colder the heat transfer medium, the faster the heat transfer rate, the faster the water would freeze.
