How did rumford cannon boring experiment provide evidence for the caloric theory?
The Rumford cannon boring experiment showed that heat could be produced indefinitely through mechanical work, without the need for a finite amount of caloric to be consumed. This contradicted the caloric theory, which proposed that heat was a material substance that could be transferred but not created or destroyed. Therefore, the experiment provided evidence against the caloric theory and supported the later development of the concept of conservation of energy.
What was the prevailing theory of heat during Benjamin Thompson's time?
The prevailing theory of heat during Benjamin Thompson's time was the caloric theory, which posited that heat was a fluid substance called "caloric" that flowed from hotter bodies to colder bodies. This theory was later replaced by the kinetic theory of heat, which described heat as the motion of molecules.
Which scientist believed in the caloric theory?
Antoine Lavoisier was a scientist who believed in the caloric theory. He proposed that heat was caused by the motion of caloric fluid in materials.
When energy balance in the body is positive body mass decreases?
This statement is incorrect. When energy balance in the body is positive (caloric intake exceeds caloric expenditure), body mass increases. To decrease body mass, energy balance must be negative (caloric intake is less than caloric expenditure).
What are the differences between caloric and kinetic theories of heat in the 18th century?
In the 18th century, the caloric theory suggested that heat was a fluid substance called "caloric" that flowed from hotter bodies to colder ones. On the other hand, the kinetic theory proposed that heat was due to the motion of particles within a substance. The kinetic theory eventually replaced the caloric theory as a more accurate explanation of heat transfer.

When your caloric balance status is in caloric excess you will?
Gain weight.

What is outcome goals for caloric intake expenditure?
By reducing caloric intake, one would lose weight. By increasing caloric intake, you'd gain weight.
What happens if your daily caloric intake is the same as your caloric output?
weight maintenance will occur
If your average daily caloric intake is less than your average daily caloric output?
you will lose weight
Why are you not making any significant gains with your weight training?
Caloric burn MUST exceed caloric intake.
What is caloric value?

What happens when your average daily caloric intake is less than your average daily caloric output?
you gain weight
What is the caloric value of lipids?
Lipids do indeed have a high caloric value.
What caused the caloric theory to be abandoned?
The caloric theory came under attack soon after its introduction. It maintained that heat is a substance that could not be created or destroyed. Yet it was known that heat can be generated indefinitely by rubbing one's hands together or rubbing two pieces of wood together. In 1798, the American Benjamin Thompson (Count Rumford) (1753-1814) showed in his papers that heat can be generated continuously through friction. The validity of the caloric theory was also challenged by several others. But it was the careful experiments of the Englishman James P. Joule (1818-1889) published in 1843 that finally convinced the skeptics that heat was not a substance after all, and thus put the caloric theory to rest.
