It will rise from the moment it is heated - for example, from the moment it has contact with the body. But it is expected to stabilize after a few minutes.

Time it take for light to get to Mercury?
it takes about 3-4 minutes for light to travel to mercury
How long does the light from the sun take to get to mercury?
It really depends on the current distance of Mercury from The Sun. The orbit of Mercury (and of all the planets) is not perfectly circular. There are times Mercury is closer to The Sun than other times. When it's at its closest, or perihelion, Mercury is a little over 28.5 million miles from The Sun, and light takes just over 2 minutes and 33 seconds to travel from The Sun to Mercury. When Mercury is at is farthest distance, or aphelion, it is almost 43.4 million miles from the Sun, and light takes just over 3 minutes and 53 seconds to travel from The Sun to Mercury. So, based on the dates that Mercury is at aphelion and perihelion, your answer is: On August 21st, 2009, light takes 3 minutes and 53 seconds to travel from The Sun to Mercury On October 4th, 2009, light takes 2 minutes and 33 seconds to travel from The Sun to Mercury.
What are the 3 types of thermometer?
The three types of thermometer are oral, rectal and tympanic. The most reliable is the rectal thermometer.
What is an instrument that measures changes in air pressure using liquid mercury?
Any liquid can actually be use in a tube (barometer) to measure air pressure, but there are various advantages in using mercury for the purpose. 1. Mercury is a shiny liquid (a liquid metal) so it can be easily seen through the glass tube. Other liquid like water are transparent. 2. Mercury is very heavy. So only 76cms of it rises in the tube. Had you been using water for the purpose, you would need a glass tube as long as 55ft. 3. Mercury does not stick to the glass surface inside, so the reading obtained is much more accurate and precise. Remember: Water droplets stick to glass.
Calculate the time it takes light from the sun to reach Mercury?
Mercury's average distance from the sun is about 58 million kilometers, or 58 billion meters. Light travels at a speed of about 300 million meters per second. Divide the distance by the speed of light to get the time needed, and you end up with about 193.3 seconds, or about 3.2 minutes.You can check this answer to make sure that it makes sense by remembering that light from the sun takes roughly 8 minutes to reach Earth. Earth and Mercury are both terrestrial planets, Mercury is closer, and 3 minutes and 8 minutes aren't wildly different times, so the answer looks reasonable.
How long should you keep the thermometer under your tongue?
You must hold your mouth closed and keep the thermometer in place for a certain period of time. If you have a digital thermometer, it will tell you when it's "done". If you are using an old "mercury thermometer", the thermometer must stay under the tongue for at least a minute to 2 minutes.NOTE: Mercury thermometers are being phased out. The mercury inside is highly toxic and you should dispose of all mercury thermometers by taking them to a recycling center that handles that. DO NOT THROW IT IN THE TRASH. Mercury is poisonous to every living thing.UPDATE: GERATHERM offers MERCURY FREE thermometers that work the same as the mercury ones. They are supposed to be safe.
What are the four kinds of thermomether?
1. Alcohol or spirit thermometer 2. Mercury thermometer 3. Liquid crystal thermometer 4. Quartz thermometer 5. Reversing thermometer 6. Resistance thermometer
Why do you use mercury thermometer?
As tempertature rises, the Mercury in the thermometer expands, causing it to go up. As temperature decreases, the mercury in the thermometer contracts, causing it to go down on the scale. However, mercury thermometers are very dangerous if it breakes and gets on your skin. so it it reccomended to use an electric thermometer. these thermometers use thermoelectric current to measure temperature. ergo. they are safe if they break cheers <3 -Eli

How do you take temperature with a clinical thermometer?
Step 1: Clean your glass thermometer with isopropyl alcohol before using it, then dip the tip into some cool water, or wipe with a tissue, to remove the taste of the alcohol. Step 2: Shake down your glass thermometer until the mercury line is below 96.6 degrees F. Step 3: Slide the tip of the thermometer under one side of the tongue, well into the back of the mouth. Step 4: Close your mouth around the thermometer using your lips - don't clench the glass thermometer with your teeth. Breathe through your nose, with your mouth closed. Step 5: Leave the thermometer under your tongue for 3 full minutes. Step 6: Remove the thermometer and hold it under a bright light, so you can see how high the mercury has risen. An arrow will point to the normal temperature, which is 98.6 degrees F.
What is normal temp for rat terrier?
A rat terrier's normal temperature is 101 to 102.5 degrees Fahrenheit (38.3 to 39.2 degrees Celsius). To take your dog's temperature, you'll need a rectal thermometer. Put some petroleum jelly on the bulb of the thermometer. Ask someone to hold your dog's head while you lift his tail and insert the thermometer about an inch or so into the rectum. Do not let go of the thermometer. Hold it in until the temperature is read (about 3 minutes for a mercury thermometer), and then remove gently.
How do you use the clinical theamometer?
1.shake the thermometer vigorously so that the murcery goes below the normal mark 2.keep the rhermometer either in the armpit or under the tongue of the person whose temperature is to be taken 3.wait for 2 minutes 4.take out the thermometer and read the mark where the silver mark of mercury ends
How long does it take the sunlight to travel to mercury?
It takes approx 3 minutes.
How many minutes to get the body temperature using a thermometer?
The time required is as follows: 3 minutes if used in mouth and 5 minutes if used under the armpits. One degree is added in the last instance.
What instrument measures changes in temperature?
Temperatures are measured by instruments called thermometers.The instrument usually used to measure air temperature is the maximum-minimum thermometer. It consists of a U shaped tube with bulbs at each end and mercury at the bottom. Air heats or cools the bulbs causing the air inside to expand or contract, therefore pushing or pulling the mercury upwards or downwards.There are 3 types of thermometer: minimum thermometer, maximum thermometer,and the "Six's thermometer" -- these record the temperatures over a period of time.it says in my book that a thermometer measures air temperature
