when we rub our hands some heat is produced. may i know why?

Answer 1

we know that energy exists in different forms and one form may get converted into another. When we rub our hands together, mechanical energy through friction between our hands. In the same way the tyres of a car heated up as the car moves, due to friction between the tyre and the road.

Answer 2

When you rub your hands against each other the friction between the two surfaces converts the kinetic energy (from the rubbing) into heat which is what you feel in your hands.

Answer 3

You are converting work (rubbing your hands takes energy / calories) into heat energy. The rougher your hands, and or the faster you rub them the more energy you are using, and therefore the more heat you will feel on your hands.

Friction is the force opposing your hand rubbing, which is a larger force if the surface is rough, you press your hands together harder, or if you rub faster. The larger the opposing force, the more work (think energy) you have to put into rubbing your hands, the more heat energy you create.

Answer 4

rubbing any 2 objects together usually produces heat because of the friction between the objects. It takes energy to rub your hands together, and that energy is dissipated as heat.

Answer 5

Well congratulations and I am sorry to hear about the problem. I know first hand how heart retching, emotional and physically draining this can get so when the mom and pups sleep you rest as well. The tube feeding is the best way for what you are doing and you need to have someone show you the proper way. You do not want to a.) Get fluid in their lungs and b.) Let them become dehydrated. Either could kill them. If you don’t know how to check for dehydration, pick the skin up off the back of the neck or just the back to check for elastically. If it does not spring back almost immediately they are starting to get dehydrated and you will have to get a little more aggressive in giving them fluids. Increase the amount you are giving them and shorten the time in between feedings. Example if you are giving them 10cc every 3 hours, up it to 12-14cc every two hours. And call your vet for proper dosage. Keep them and mom warm. Set up the box to be an incubator type situation but not so hot they get dehydrated. Keep all traffic out, except for you and one other person to fill in for you if you are gone or resting. Hope this helped Good Luck and ask your vet or a friend if they know someone that might mentor you. It is not your fault or the puppies; you just need guidance and help.

Answer 6

Heat is produced in this situation because of friction.

Answer 7

Friction is turned into kinetic energy which then turns into thermal energy. This caused because the atoms in your hands are gaining a lot of kinetic energy in motion, therefore, the temperature rises in your hands.

Answer 8

When u rub ur hands, there is friction between ur palms and heat is produced.It is due to transformation of energy.The kinetic energy of ur hands gets converted into heat energy.

Answer 9

Because of friction. Friction is the force that opposes the relative motion or tendency toward such motion of two surfaces in contact.

Answer 10

due to friction.....when we rub our hands, mechanical energy changes into heat energy
