Homemade Thermometer In middle school your child will be learning all about heat energy and temperature measurement‚ and will likely get to use a lab thermometer. This project will enable your child to construct a homemade thermometer that will compliment what he’s learning about this instrument in school. What You Need: * Tap water * Rubbing alcohol * 11-ounce clear‚ narrow-necked plastic bottle * Red food coloring * Clear plastic drinking straw * Modeling clay *

the capillary tube‚ I recorded the temperature. I then repeated these steps two more times and took the average of the temperatures. The next step was to determine the melting point of acetamide. I crushed the acetamide and filled the capillary tube with 2mm if the powder. I then attached the capillary tube to the thermometer and put it into a beaker that is half filled with water. I then heated the beaker and when the acetamide melted I recorded the temperature. Observations Data Table 1: Experiment

the purity of a mixture using melting point tests. • In order to determine the melting point of a substance whose melting point was higher than 100 degrees Celsius you would use oil or glycerol just to achieve a higher temperature so you can run measurements at those high temperatures. Melting point can be measured very precisely at least for pure compounds. • Adding more crystals in the capillary tube would cause there to be errors in the experiment. If too many crystals were added‚ it would cause

various components (called fractions)‚ is to do it using the differences in boiling temperature. This process is called fractional distillation. You basically heat crude oil up‚ let it vaporize and then condense the vapour The various components of crude oil have different sizes‚ weights and boiling temperatures; so‚ the first step is to separate these components. Because they have different boiling temperatures‚ they can be separated easily by a process called fractional distillation. The steps

Allow about 15 min for the mixture to come to equilibrium and then measure and record the temperature of the mixture. Theoretically‚ this temperature is 0°C. Set up a beaker

the ensuing temperature variation around either wall may be predicted. Contrary to what might be expected‚ the waI1 temperature variation is very substantial in turbulent as well as laminar flow.

Why does snow melt in the sun at temperatures below freezing? The rate of snow melt is dependent on energy availability‚ which is mostly in the form of radiation. Cold snowpacks have a negative energy balance‚ but warming causes the snowpack to become isothermal and additional energy results in positive energy balance and melt. Daily snow melt in forested areas is considerably less than melt in open areas‚ as forests protect the snow cover from solar radiation and wind. Canopy warming can increase
