Conduction and radiation.
Heat always flows from the hotter of two objects into the colder - until their temperatures are the same.
To measure heat temperature. (thermo- meaning heat; -meter meaning measure)
OK basically depending on what thermometer. the glass tube is filled with either alcohol or Mercury. and when it gets hotter, the liquid expands and takes up more space inside the tube. and colder.......the liquid compacts and moves down the tube.....and it's taken years to calabrate the markings on the tube to show the correct reading.
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
Basically you have two different kinds of metal with different coefficents of expansion put together. As they expand it creates a curving effect because one is expanding more than the other. This drives the needle and gives the indication. http://en.wikipedia.org/wiki/Bi-metallic_strip

A thermometer measures temperature using a temperature-dependent physical property, such as liquid expansion or electrical resistance. A thermocouple, on the other hand, generates a voltage proportional to the temperature difference between its two junctions, based on the Seebeck effect. Thermocouples are typically used in more extreme temperature environments compared to thermometers.
To find relative humidity using a wet bulb and dry bulb thermometer, first measure the temperature with both thermometers. The dry bulb thermometer provides the air temperature, while the wet bulb thermometer, which is moistened and exposed to airflow, measures the cooling effect of evaporation. Using the readings from both thermometers, you can refer to a psychrometric chart or use a formula to calculate the relative humidity based on the difference in temperatures. The smaller the difference between the two readings, the higher the relative humidity.
Using an uncalibrated thermometer can result in an incorrect measurement of the boiling point of a liquid. This can lead to inaccurate data for experiments or cooking processes. It is important to calibrate thermometers regularly to ensure accurate temperature readings.
Some pool thermometers do contain mercury, but there are alternatives available that use different substances like alcohol or digital sensors. If you are concerned about the presence of mercury in a pool thermometer, look for options that explicitly state they are mercury-free.
It generally made using fluid which expand or contract linearly with temperature such as mercury, water or alcohol. Electronic thermometer use the relation of thermal property effect electrical conduction difference to measure temperature.
The thermometer reading will change from reading the solution temperature.

It would depend on a contingency of variables. Being, how hot is the substance that it is being removed from, the temperature of the room, how long it takes from the time removed from the liquid until it is read, and the type of thermometer reading device.
temperature is a measure of effect of heat energy. It tells us about the degree of hotness or coldness of a body. Increase in volume, change in specific resistance, emmision of electro magnetic waves (like Light) are the general effects of the temperature. Based on these principles temperatures are measured. Change in volume --- Liquid thermometers -- Mercury thermometers Change in resistance --- Resistance thermometers ---- digital thermometers Emmission of E/M waves --- Radiation thermometers --- Pyrometers RAMKI--India
One of the problems with water in a thermometer is the effect of capillary action - the column of water tends to "stick" to the sides of the thermometer and create a U-shaped surface at the top. This makes it very difficult to read the thermometer. Previously mercury was considered to be a good medium for thermometers, but this has been discontinued due to the health risks from a broken mercury thermometer; the current medium in thermometers is dyed ethanol or methanol.
A thermometer measures the amount of thermal energy a material has. This thermal energy is related to the vibrational and rotational energy the particles in the material have. By using the thermometer to measure the temperature of a material you are, in effect, measuring the amount of energy the particles of that material have.
Yes, definitely you can keep the meat thermometer while it is cooking inside the oven. There are some types of food thermometer that allows the thermometer to remain inside the food while it's cooking in the oven. There are bimetallic coil food thermometers that are safe to use inside the oven. These oven safe bimetallic coil food thermometer are especially used in thick meat and for roasting.
