hope it helped
Well, not only three that i know... Keeping a spoon in a boiling pot of water and waiting 5 minuites and touching it again can burn your hand. the heat transfered from the water to the spoon and now the spoon in hot.
Yes, hot objects can transfer heat to other objects through a process called radiation. This type of heat transfer occurs without the objects needing to be in direct contact with each other.
No, touching fire will most likely result in burning yourself because fire is hot enough to cause burns. It is not safe to touch fire without proper protection.
A hot iron emits infrared radiation, which is a form of electromagnetic radiation that is invisible to the human eye but can be felt as heat.
The hand detects temperature through nerve endings called thermoreceptors. These receptors send signals to the brain when they come into contact with hot or cold objects, allowing us to perceive the difference in temperatures. Our brain then processes this information and gives us the sensation of feeling hot or cold.
Extremely hot. It'll burn you without touching it
A hot iron will get hotter because hot rollers come off the heating element when you add them to your hair, but the flat iron has the heating element touching your hair at all times with a steady stream of heat
if it is not as hot any more (you have to watch out for that)
tell him hes handsome, or cute...
all you have to do is beat a level with a bomb berry without touching it
Generally, there will be steam coming out of hot water. Also, you will notice when you are turning the taps on, one will say have a C on it, and the other will have H on it, although, of course this varies in different languages. But, some just have a blue spot for cold and a red spot for hot.
It is a muscle reflex. A very fast, involuntary muscle contraction. Because of this, it causes you to jerk your hand away after touching a hot iron.
Answer this question… mechanoreceptors apex
when we touch a hot object we immediately (even without thinking) withdraw our hand. touching the hot object is the stimulus and withdrawing our hand is the response
Just one exmple of matter at a higher temperature touching matter at a lower temperature is soldering. If we apply a hot soldering iron to solder and copper when making something out of stained glass, the hot soldering iron transfers heat (thermal energy) to the solder and copper (thus melting the solder and causing allowing it to flow).
To shape metal you must hit it when it's hot. The colder iron, the less easily you can shape it. In addition, it can break if it's not hot. When iron is heated sufficiently, it becomes plastic, and it can be deformed without breaking. It can be worked easily and effectively by a smith when it's hot.
