One would think that you use more energy when hot, because it makes everything in your body move faster.
To transfer heat from hot to cold, you can use a method like conduction, convection, or radiation. For cold to hot, you would typically need to add energy to the colder object, such as through heating elements or flames.
We use nuclear energy on a limited basis due to its instability. One reason we do not use it more is because the energy is not sustainable. There are two types of nuclear fission. Hot fission and cold fission. Hot fission is currently the only method we know how to utilize. Cold fission produces approximately 10 times the energy and produces fewer radiation spikes. We simply do not know how to initiate cold fission.
Probably not. If a refrigerator were in a room so cold that the outside temperature caused the refrigerator to be very cold inside, the thermostat in the refrigerator might not ever cause the device to actually use any energy. For most normal purposes, the refrigerator will be better off in a cooler room simply because the outside atmosphere will not be constantly warming up the fridge from the outside. Think about how much more you need the air conditioning on to keep a room at 70 degrees on a hot day than on a cold one.
Yes, UV lights can get hot when in use due to the energy they emit.
Using a washing machine on a hot cycle can be more expensive because it requires more energy to heat the water to a higher temperature. This extra energy consumption adds to the overall cost of running the machine.
No, its more energy efficient.
A starfish has a great ability to ensure that they don't get too hot or cold. They will reserve energy and use it as they need it. If they are in cold waters, they use more energy to warm themselves up.
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.

In the winter it's cold and you need energy to keep you warm and in the summer it's hot you don't need energy you let out energy when you sweat etc.
ONLY USE COLD WATER for a swollen eyelid. Hot water stimulates the cells and makes it more swollen.
I use cold.
The house had hot and cold running water. When I had the flu, I alternately felt hot and cold.
Colder more than hot. They are Swiss MOUNTAIN dogs after all. :)
Particles move slower in cold solids. In the solids, they are more compact and closer together. Particles move slower as temperature drops, so particles in this case move slowest in cold solids. This is because the higher the temperature the particles receive, the more kinetic energy they get as well, and thus the faster they move. If it helps, try thinking of when your cold. You use energy to warm yourself up by moving around, rubbing your hands, even shivering, this is all in an effort to raise your body temperature, so the more movement, the more energy and therefore the higher temperature! Hope this helps! :)
They use more energy because it gets cold
hot and cold b/c Hot + Cold = warm which is the best temp
