Muscles are metabolically active - they use energy in order to perform their functions. Calories are the energy, hence muscles use (burn) calories in order to function.
Fat is metabolically inactive - it doesn't useenergy, it stores it.
Since muscle contains more water, and water has a slightly higher "specific heat", yes, you could say that muscle retains more heat than the equivalent amount of fat would retain. Remember too that muscle PRODUCES heat, even when it's not working hard muscle is converting energy to heat. Fat just sits there.
With the proper mix of healthy diet and exercise, you can replace fat with lean muscle. After a few weeks you will start noticing big changes in your body.
because of ya mum
Metal baths (enamel on steel or cast iron) retain more heat than their acrylic or fiberglass versions
yes
muscle's are more apt to stiffen if the horse is allowed to stand, and moving muscle's dissipate heat better than stationary ones.
no. glass retains the heat for almost twice as long.
Black actually dissipates heat faster than other "colours" or say chrome.
Because it is less dense. The ability of a material to absorb or retain heat is governed by its molecular density, and is known as "specific heat". Wood, which is cellulose, has a much lower density than metals, and will both heat more slowly and cool more quickly in air. Lighter metals, such as aluminum, similarly display a substantially lower ability to retain heat than denser metals such as iron. When cooling materials, light metals or porous wood can be effectively cooled by the air (a low specific heat), while other denser substances are more effectively cooled by water (higher specific heat, and can absorb heat by evaporating).
no fat is more jigglely than muscle
That is not a straightforward answer because heat isn't produced by body weight but as a waste product of metabolism. The more metabolically active a tissue is, the more heat it will generate. So like muscle tissue will generate more heat than adipose (fat) tissue.
For heat loss to be an advantage to humans rather than a disadvantage, the heat lost must be equal to that produced.
to stay warm/retain body heat.
Oil will retain the heat longer than water.
