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.

What does a thermometer tell you?
A thermometer measures temperature. It tells you how hot or cold something is by showing a numerical value on a scale.
What does it mean for something to be hot or cold?
Something is hot when it has a high temperature, while something is cold when it has a low temperature. Temperature is a measure of the average kinetic energy of the particles in a substance.
What has more energy something hot or something cold?
Something hot has more energy than something cold because temperature is a measure of the average kinetic energy of particles in a substance. Higher temperatures correspond to higher kinetic energy levels.
What tool can be used to measure how hot or cold something is?
A thermometer can be used to measure the temperature of an object or environment, indicating how hot or cold it is.
What is the measure of how hot or cold something is specifically a measure of the average kinetic energy of the articles in an object?
Temperature is the measure of how hot or cold something is. Temperature is specifically a measure of the average kinetic energy of the particles in an object.
What is used to tell how hot or cold something is?
The temperature of the object will provide this information.
What does temperature tell?
Temperature tells what degrees it is like how hot or cold something is
How can you tell hot from cold?
usually the hot will be steaming so you know that is hot and what is not steaming could be cold
What is the difference between ectothermic and endothermic?
endothermic is when something changes from to hot to cold and ectothermic is when something changes from cold to hot.
