Why is heat produced in a wire when current is passed through it?
I am not sure what exactly happens at the quantum level; and it might be quite complicated. But you can imagine some electrons, that usually make up the current, bumping into atoms or other electrons, and losing their energy. That "lost" energy, of course, is converted into heat.
What is the tendency of water to resist temperature change?
High specific heat of water due to it's polarity. Many hydrogen bonds are forming and reforming constantly so that energy added to water has more difficulty breaking these bonds and this resists temperature change in the upward direction.
Is your tongue more sensitive to salty taste or sweet?
It depends on your tongue, cause everybody's taste buds are different.
What has more sensory your tongue or foot?
foot
What happens if you heat up a lemon?
Absolutely nothing. Lemon just tastes very sour, nothing more. It is possible that the tongue can go through extreme pain and stay for a day and you can lose the ability to taste anything sour.
Is the tongue or finger more sensitive?
The finger is more sensitive to touch. The tongue is more sensitive to temperature. Test it out for your self!
Does your fingers or your tongue have more nerve endings?
Finger tip has numerous nerve endings and that's why they are too sensitive. Similar is the case with tongue which has numerous nerves in order to propagate the taste sensation from the taste buds on the tongue
Where can you be shot and not die?
this one is easy. lots of places. tip of any finger , any toe , in the middle of your hand, in the tongue (when sticking it out) , ear , nose (from the side) , and any where from the forearm to the finger tips. (there also may be more)
Why doesn't talking help a tongue piercing heal faster?
The friction irritates the piercings and reopens it in a way. Like, if you had a gash on your finger. You wouldn't want to move the finger because you would just keep the wound open and cause more pain.
Does the color violet deflect or resist heat more than other colors?
Darker colors absorb light and heat....Lighter colors refract...so violet is the closer to last on the list of colors that refract.
Why do cattle resist the heat of the sun?
Most do not. There are many breeds of cattle that do not nor cannot resist the heat of the sun without succumbing to it. Black-coloured thin-hided cattle are more apt to become heat stressed than those who are lighter coloured and/or have thicker hides. Angus cattle are less adapted to the southern USA, for example, than other breeds like Herefords, Gelbvieh or Brahman.

Why do babies put things in their mouth?
The tongue and mouth contain many more nerve endings than the hands and hence can provide information in much more detail (try feeling in the side of you mouth with your tongue and your finger and compare the difference in what you feel). By putting things in their mouths, babies are simply trying to discover their shape and size.
What will take in more heat a silver spoon or a wooden log?
wooden log, the silver spoon would melt at a lower temperature than the wood could resist. (Im not 100% on this though! melting pt for silver is about 900 C)
What is a scientific principle concerning a transfer of heat that takes place during the evaporation of liquids?
The latent heat of evaporation - (if you wet your finger and then blow on it it feels cool this is because the evaporating water takes heat out of your finger). This heat is recovered when the liquid re-condenses - (water droplets forming on the outside of a cold glass of beer heat the glass with this recovered energy and the beer in the glass warms up far more quickly than it would if the air was dry).
Why do employees resist change?
Employees may resist change because of fear of losing their current positions. They may also resist because they believe the change will put them under more scrutiny or put more pressure on them.
