High energy density means that there are a lot of calories in a small portion of food, while lower energy density means that there fewer calories in a large portion of food.
Not exact matches
Supercapacitors have a much
higher energy density than batteries,
meaning they can charge and discharge extremely quickly; this is useful to meet quick spikes in electricity demand on the rail system.
Conversely, batteries have
high energy density and low power
density, which
means they can last a long time, but don't deliver a large amount of
energy quickly.
Researchers were able to cut people's caloric intake nearly in half, from 3000 calories a day down to 1570 without cutting portions, just by substituting less calorie dense foods, which
means lots of fruits, vegetables, whole grains, and beans, compared to a
high energy density meal with lots of meat and sugar.
this should
mean that normally your appetite is suppressed so you while it is a
high fat diet in terms of calorie profile, it is not a lot of fat because of the
energy density.
Foods with
high energy density,
meaning they pack the most calories per gram, included candy, pastries, baked goods and snacks.
It also has
high power
density,
meaning that it produces more
energy per gallon than many other liquid fuels.
So it's all gases at greatest
density will be doing the same thing around the planet at the same time (*) and as these change with differences in
density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the
higher one goes, then,
energy conservation intact, the hotter will rise and cool because losing kinetic
energy means losing temperature, thus cooling they which began with the closest in
density and kinetic
energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.
Well, in my opinion, it
means we need to treat our liquid fuels (with
high -
energy density) as very precious resources as we have yet to prove that we can create a renewable liquid fuel even nearly equivalent to gasoline (petrol) or diesel.
