To make your own homemade thermometer, a person will need a plastic bottle, a clear straw, some putty, water, rubbing alcohol, and food coloring. Fill a quater of the bottle with equal parts water and rubbing alcohol. Add a few drops of food coloring to help see the change in temperature. Place the straw in the bottle and seal the top completely with the putty, making sure the bottom of the straw does not touch the bottom of the bottle. The liquid will rise and fall through the straw when the temperature changes.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
he made the thermometer
a liquid thermometer is made with a glass "shell" and ussually have murcur inside them that dilates when it gets hotter and rises and contracts when its colder and lowers- this has been made by a 12 year old boy
He met Olaus Roemer, a Danish astronomer living in Copenhagen, Denmark. He invented the alcohol thermometer and he realized the scale was unbalanced. So he decided to make his own thermometer and universal accurate scale.
A gas thermometer is a device that measures temperature by the variation in volume or pressure of a gas. It is made by filling a bulb with gas such that the volume of the gas in the bulb remains constant.
by old designed using styrofoam,adjustable kerosene lamp,thermometer
It is then 'homemade'
Galileo made the thermometer in 1593.
It is homemade, as in homemade bread and cakes, etc
Yes, it is. It means made at home, or personally, or designed to mimic things so made. It can also mean jury-rigged or improvised.
Anything that is not pre-packaged is considered to be homemade in cooking. Homemade soup is made with fresh vegetables instead of canned.
made at home
one is homemade and one is factory made...
Homemade means exactly as it says. Anything that is made at home for example 1) cakes or cookies baked at home are homemade confectionary 2) sewing or knitting = home made dresses or jumpers
Using a thermometer we can measure the temperature.
Galileo Galilei made a water thermometer in 1593.
The numbers are where they are because the person who made the thermometer scale decided which numbers go where.
