Thermoscopes were the earliest types of thermometers and they only showed changes in temperature but didn't show any scales. ]]> 2022-03-07 18:36:18 UTC https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082304871 Daniel Fahrenheit created the first alcohol thermometer (1714 - 1724) 2900628 https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082324155  ]]> 2022-03-07 18:46:09 UTC https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082324155 Daniel Fahrenheit Introduced the temperature scale which bears his name was used on the thermometer (1724) 2900628 https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082334941 Fahrenheit thermometer ]]> 2022-03-07 18:51:36 UTC https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082334941 Andres Celsius introduce his temperature scale which means consisting of or divided into 100 degrees this scale is also known as the "centigrade" scale (1742) 2900628 https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082344029 2022-03-07 18:56:28 UTC https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082344029 Galileo galilei invented a rudimentary water thermometer in which, for the first time allowed temperature variations to be measured (1593) 2900628 https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082351603 2022-03-07 19:00:36 UTC https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082351603 The term "Celsius" adopted by the interaction conference on weights and measures in Celsius (1742) 2900628 https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082401029 2022-03-07 19:27:23 UTC https://padlet.com/2900628/45eaya96n9ydjea2/wish/2082401029 The electrical-resistance thermometer was invented in Germany.
