LABORATORY THERMOMETER (-10°C - 110°C)

Product Information

Molecules, such as oxygen (O 2), have more degrees of freedom than single spherical atoms: they undergo rotational and vibrational motions as well as translations. Heating results in an increase of temperature due to an increase in the average translational kinetic energy of the molecules. Heating will also cause, through equipartitioning, the energy associated with vibrational and rotational modes to increase. Thus a diatomic gas will require more energy input to increase its temperature by a certain amount, i.e. it will have a greater heat capacity than a monatomic gas. If you have an HSA or an FSA account, know that over-the-counter digital thermometers are eligible for reimbursement without a prescription.

Use this brilliant Thermometer Science Experiment to get your children thinking about liquids and heat, and how they can be measured. When measuring different temperatures, wait at least one minute between readings to allow for accuracy. This process takes about 30 seconds, which is really fast compared to mercury thermometers, as they take 3 minutes to heat up and give you a reading! Alongside the step-by-step instructions, there is a clear explanation that helps your children with the science happening in front of their eyes.Temperature Measurement by L. Michalski. Wiley, 2001. A detailed guide to precise temperature measurements for scientists and engineers. Place the thermometer in the center of the container and make sure that it is not touching any sides or bottom. Mercury thermometers are accurate and have been used since the 1700s. But since mercury is a hazardous substance and can be deadly if inhaled from a broken thermometer, few governments and agencies now support the use of mercury thermometers at home.

Cons: Very loud beep, must turn off and on between readings, colored fever alerts misleading, coin cell battery is more annoying to replace Photo: Alcohol thermometers. As you can just see from the red lines alongside their scales, these historic Dr Pepper thermometers at the Dublin Bottling Works and W.P. Kloster Museum in Dublin, Texas also contain alcohol.

Using simple materials, you can carry out this experiment either at home or in the classroom. Here are the household items you will need:The glass tube of a thermometer usually contains mercury. Mercury is perfect to test temperature because it changes from a solid to liquid very easily. Fill the glass container: Fill a large container with crushed ice, and then add clean cold tap water until it’s filled up. Then stir the mixture. Use the Heat Sources Sorting Worksheet for activity on how to categorise different sources of heat. Challenge them to put items such as toasters, candles and greenhouses under the correct headings. What is happening in the Thermometer Science Experiment? There are separate buttons for "head" and "ear," and to change from one to the other, you need to snap on or off the top cap of the thermometer, which I found a little difficult but still doable. A single kelvin is referred to as a unit, rather than a degree, and is equal to a single degree on the Celsius scale. The Kelvin scale is mainly used by scientists.
