how does we measure temperature
Answers
Answer:
we can measure temperature with the help of thermometre
Answer:
Temperature is a measure of energy or heat. There are several ways to determine temperature. One way is by just using your senses. Objects with more energy will be warm or hot to the touch. Things with less energy will be cool or cold to the touch.
A more accurate way to measure temperature is by using a thermometer. A thermometer is the instrument used to tell the air temperature. A thermometer is usually made up of a small, hollow glass tube. At the bottom of the tube is a bulb, which holds a liquid such as alcohol or mercury.
When there is an increase in heat, the liquid inside the bulb expands, pushing up into the tube. A decrease in heat lets the liquid contract, moving down the tube. A measuring scale is attached to the tube, to give an accurate measurement of heat energy.
