Heat is transmitted through conduction (touch), convection (flowing) and radiation (rays).
When you hold your hand beside a flame the radiated heat will reach you (it radiates out in all directions like the light), but not much of the convected heat, because convected heat flow is upwards (most things expand as they heat up, so they get lighter and rise), and you will not get heat from conduction unless a burning spark flies out and touches you and conducts the heat directly.
With your hand above the flame you are receiving heat from radiation and convection.
With your hand in the flame you would get heat from radiation and convection and conduction.
The hottest part of a flame is the position where most intense combustion is occurring. If you look at a flame there is usually a small more transparent area near the base of the flame. The boundary between this and the bright area above at the centre of the flame is the hottest area. (This is why when using a gas welder you focus this part of the flame on the metal area to be welded.)

∙ 12y agoI think its because the heat his radiating off the flame towards cold areas. Therefore your finger doesn't burn IN the flame but on the outsides of it.

Why if your hand is held high above a burning candle does it feel heat?
Air near the flame is heated and rises, thus reaching your hand. This is heat transfer by convection.
What happens to your hand when you place it above a lighted candle?
it gets warm
Why if your hand is held near to the side of a flame does the front of your hand feel heat?
Mostly the heat you feel will be radiation from the flame, which travels in straight lines. Thus it hits the side of the hand nearer the flame.
Why when a drop of wax from a burning candle falls on your hand do you feel heat?
Heat is transferred to your hand by conduction. The particles of the wax are moving faster than the particles in your skin and energy is transferred by collisions between the two sets of particles.
Why can't you stick your hand through a solid?
You cant cause the molocuels are to tightly packed thus making a barrier like a forcefeild
What earth process would it be if you put your hand next to a candle flame it doesnt really hurt but if you put your hand directly above the flame you burn yourself?
The process of heat rising would be the earth process in force if a candle is touched on the side and it is cooler than a hand over the candle. The hand over the candle will get burned because of the direction of the heat of the flame.
Why is it hotter if you put your hand above a lighted candle than at the sides if the candle's flame?
Yes it is - since heat rises.
Holding your hand 30 centimeters above the flame of a candle you will receive the most heat by means of?
Radiation

What makes a fire bigger?
Fire can make itself bigger because it is a self controlled gas. But I put hand sanitizer in a candle and then lit the candle and kept squirting sanitizer in the flame. The fire roared! Sanitizer can really get a flame going!
How do you snatch the flame from Master Xi's hand in world of warcraft?

What is brandy warmer?
A brandy warmer is an alternative to warming the brandy balloon by hand. It is a wire cradle with a small T light candle at the base. You light the candle and place the brandy in a brandy balloon in the cradle over the flame and let it warm to the right temperature. Quicker but not as civilized as warming it in your hands!!

Mostly the heat you feel will be radiation from the flame, which travels in straight lines. Thus it hits the side of the hand nearer the flame.
How do you keep a candle lit?
by keeping your hand over it par.
What song is this close your eyes give me your hand darling do you feel what I?

How safe are candles?
candles are safe but you have to be careful not to get too close to them to where your hand could touch the flame. Many people have done that before just to see what it would do and many found out the incorrect way.Mackenzie
