The Challenge: Make a Thermometer |
Page: 1 2 3 4 5 6 |
There are different
kinds of thermometers, such as electronic, glass, resistance and gas.
Which of these would the Rough Scientists attempt to make with just the
most basic equipment?
What are
we trying to measure?
Temperature is a measurement of how hot or cold a substance is. Temperature
indicates how much energy the atoms inside the substance have. The more
energy the atoms have, the faster they move and the hotter the substance.
For each substance,
there are specific temperatures at which changes
of state happen. These are known as melting and freezing points. Absolute
zero (-273oC, or -459°F) is the coldest temperature that we can get to
and represents the temperature at which all movement of atoms should stop.
Temperature is measured in degrees Centigrade (or Celcuis) by thermometers.
