Because your finger doesn't give you a number for temperature. And also, if the liquid is quite warm, it can burn your finger obviously. The thermometer on the other hand is made to deal with extreme temperatures, unlike your finger. It gives a precise, almost accurate reading of the temperature.

There is no standard term "finger jellury." It might be a misspelling or variation of a different term. If you can provide more context or clarify the term, I can try to assist you better.
When you touch a metal ice tray that has just been removed from the refrigerator, condensation forms on the surface causing your finger to stick. The moisture acts as a sort of adhesive, creating a temporary bond between your finger and the cold metal surface. This effect is due to the difference in temperature between the metal tray and your warm finger.

Your ring finger is the finger between your middle finger and your pinky.
It depends on how hot I want it to be. If I want regular out-of-the-tap hot water, I stick my finger in it quickly and then shout and wave my hand about when it's actually hot. If I need boiling water to be a certain temperature, I measure the temperature with a candying thermometer.
The temperature of a finger bowl is typically lukewarm, meaning it is neither hot nor cold. It is meant to be comfortable for rinsing fingers after a meal.
Taking the temperature orally with a glass thermometer, when the patient is unconscious is risky, as the patient may suddenly wake up and bite and break the thermometer. Apart from the glass splinters, a mercury thermometer is a great hazard. The temperature could be more safely taken from the armpit, or anus, with less risk. Nowadays, most hospitals take temperatures using electronic devices that are placed into or near the external part of the ear, or are clipped to the finger and registered onto a computer like console.
Put the finger in water, temperature 100 - 104F.

Heat transfer occurred from your finger to the cold water, as heat moves from a higher temperature region (your finger) to a lower temperature region (the water) in an attempt to reach thermal equilibrium.
You can get a finger splint or better yet you can go to your family doctor and ask that.
When you dip your finger into cold water, thermal energy is transferred from your warmer skin to the cooler water. This transfer of heat occurs because heat moves from areas of higher temperature to areas of lower temperature in an attempt to reach thermal equilibrium. As your finger loses heat, you perceive the sensation of cold. The water molecules, being at a lower temperature, absorb the heat, which causes the temperature of your finger to drop.
When you dip your finger into the water, heat and kinetic energy transfer from your finger to the water. Direction of transfer goes from your finger (higher temperature) to the water (lower temperature).
18 finger dogs have 18 fingers. 20 finger dogs have 2o fingers20 finger is better dog then 18
It will implode and create a black hole. not really, it'll just measure the heat..
It determines how long you will keep your finger on it : )
