Thermos bottles are generally used to keep liquid from changing temperature for a longer period of time. Usually, one pours hot liquid into the bottle, and it will remain warm for longer, but they are also effective at keeping cold liquid cool.
you tell me if you fill a thermos with hot soup or hot chocolate put the lid on and then touch it is it hot or cold. odds are it is warm so it is hard to say. but the thermos is an insulator
thermal energy is energy caused by friction friction is when two or more objects touch kinetic energy is when somthing is falling after you realesed potential energy that's all i can tell ya
Heat and light for the earth, to keep us warm, to grow food, and recently to provide electricity for the world.
Cotton when wet exhibits a capillary effect and wicks much water into its volume. It does not keep you warm.
well mostly because we might have packed a lunch and wanted to bring something that had to stay warm. Thermos are used to keep your food warm
No. It would have to be in a thermos to keep it warm.
A thermos bottle (Actually a thermos container, which has a wider lid) will work.
Put them in a thermos :D
if its hot outside

She put the warm apple cider into a thermos so that it would stay warm at the ski resort.
yes it would keep your food warm,they are used worldwide in fast food outlets and caffes to keep cooked food warm.
A thermos is only good because of the material it is made with. A thicker material will keep whatever is inside cold or warm longer.
I usually microwave an ice pack for 30 seconds then rubber band it around the thermos.
Thermos Flasks were invented in 1892 by Sir James Dewar. They consist of two flasks, one placed over the other and joined at the neck. The main advantage of using a Thermos is to keep hot beverages hot and cold beverages cold.
Thermos are double walled containers. Between each wall, the space is vaccuum sealed, so there are no air particles. This decreases the transfer of energy (by convection) from inside the warm drink to outside in the atmosphere. The second way your thermos keeps your drink warm is the shiny surface inside your thermos. Photons carrying energy bounce off the shiny surface inside the thermos, keeping high energy photons around the infrared wavelength inside the thermos. Next time you drink from your thermos, think science!
