00:00Hi kids today we will learn measuring temperature in a thermometer. Thermometer
00:10is a tool for measuring temperature or to know how cold or hot something is. It
00:18is a vertical number line. There is a red or silver vertical line inside the
00:27thermometer. Temperature is shown in increasing order starting from the
00:35bottom on this number line on the tube. The line goes up if the temperature
00:44rises and the line goes down if the temperature decreases. Below zero degrees
00:54Celsius or temperature in minus is very very cold or ice-cold. Zero to ten
01:07degrees Celsius is cold. Ten to twenty degrees Celsius is cool. Twenty to thirty
01:17degrees Celsius is warm and 30 degrees Celsius and up is hot. Zero degrees
01:29Celsius is a freezing mark of water. Okay tell me ten degrees Celsius will it be
01:39above or below zero degrees Celsius? Look at the picture. Yes it will be above
01:50zero degrees Celsius. Tell me 20 degrees Celsius will be above or below zero
02:02degrees Celsius? Yes it will be above zero degrees Celsius. Tell me minus two
02:15degrees Celsius will be above or below zero degrees Celsius? Yes it will be
02:24below zero degrees Celsius. Good so what have we learned? We have learned that the
02:36thermometer is used to measure temperature and temperature increases as
02:44the silver line inside the thermometer rises and temperature decreases as the
02:52same line comes down and freezing point of water is zero degrees Celsius. Also
03:02not to forget below zero degrees Celsius or temperature in minus is very very
03:11cold or ice-cold. Zero to ten degrees Celsius is considered cold. Ten to twenty
03:23degrees Celsius is considered cool. Twenty to thirty degrees Celsius is warm
03:31and thirty degrees Celsius and up is hot. Good now you may go ahead and take a
03:42quiz to learn more. Bye bye!
