HeatGear styles are created with performance fabric that keeps the person wearing it "cool, dry, and light" in warm or hot conditions. ... In order to easily remember the difference between the two fabrics, just remember: HeatGear is for the HEAT and hot weather, and ColdGear is for the COLD weather. Just like it sounds!

The tricky part is knowing what situations calls for hot, and which calls for cold. Sometimes a single treatment will even include both. As a general rule of thumb, use ice for acute injuries or pain, along with inflammation and swelling. Use heat for muscle pain or stiffness.

Hot and cold is assumed on the basis of our sense only. Hotness is due to the high temperature and hence high kinetic energy of molecules in it. And Coldness is due to the very low temperature and hence very low or negligible kinetic energy of molecules in it.

Cold-blooded animals require less amount of energy as compare to Warm-blooded animals, as Warm-blooded produces heat by their own and regulate their consistent body temperature in any environment, whereas Cold-blooded animals maintain their body temperature according to changes in an environment.

Difference Between Cold-blooded and Warm-blooded Animals. Cold-blooded are the animals which cannot regulate their internal body temperature according to the required level and they keep on changing their temperature according to the changes in external environment temperature.

What's the difference between hot and cold water? ... The difference is faster molecular motion in hot water. Temperature is simply a measure of kinetic energy, the motion of molecules. In colder water and other substances, the molecules move a bit more sluggishly.

SAE 20W50 is thicker than 10W30, so it'll be longer to reach your engine parts during cold start, but the 20W50 could give your engine extra protectiom when it's heat and being used for long time running. The sound would be smoother than the 10W30 even you get less responsive on the acceleration.

Once perfected, cold forging ensures bolts can be produced quickly, in large volumes, and with high uniformity. ... Rolling works much like cold forging, and involves running the bolt through a die to shape and mold the steel into threads. Cutting involves forming threads by cutting and removing steel.

Because ice's thermal conductivity is low, like the thermal conductivity of air, an igloo works by stopping heat being transferred into the surroundings, even when the temperature is really low. The ice and the still, unmoving air both act as highly effective insulators.

In general, the greater the temperature difference between the hot and cold areas of fluid, the greater the thermal driving head and the resulting flow rate. However, it is good practice to keep the hot fluid subcooled to prevent a change of phase from occurring.
