thermometry is a branch of physics that related to the measurements of temprature.actually thermometer measures temprature,it just deal with these measurements.there are many types of thermometry i.e
1-vapour-pressure thermometry
2-radiation thermometry
3-thermocouple etc,etc
What else can I help you with?
Why thermameter not started with zero?
Probably a cheap one
Why is Mercury used in thermameter?
Mercury's melting point is close to the room temperature, so it is a good indicator of temperature around room temperature.
What type of thermameter?
It seems there might be a typo in your question regarding "thermameter." If you meant "thermometer," there are several types, including digital, infrared, and mercury thermometers. Digital thermometers provide quick and accurate readings, while infrared thermometers measure surface temperature from a distance. Mercury thermometers have largely been phased out due to safety concerns. If you meant something else, please clarify!
Why is it important to record your results over the same amount of time?
because in chemistry we have to record the result fast like if we use thermameter and take it quickiy so we can not measure it exactly
Is thermameter is instrument or equipment?
A thermometer is considered an instrument, as it is a device used to measure temperature. It is not typically referred to as equipment, which usually implies a larger and more complex set of tools or machinery.
Who invented the Mercury thermameter?
A mercury-in-glass thermometer, invented by German physicist Daniel Gabriel Fahrenheit, is a thermometer consisting of mercury in a glass tube. Calibrated marks on the tube allow the temperature to be read by the length of the mercury within the tube, which varies according to the heat given to it. To increase the sensitivity, there is usually a bulb of mercury at the end of the thermometer which contains most of the mercury; expansion and contraction of this volume of mercury is then amplified in the much narrower bore of the tube. The space above the mercury may be filled with nitrogen or it may be less than atmospheric pressure, which is normally known as a vacuum.
What is an everyday example in which you observe a gas expanding when heated?
Example of thermal expansion:Spaces or gaps left between rail lines. The reason is that the movement of trains exerts a huge pressure on the rails, this shows up a rise in temp. in the rails made up of Fe .So, the rail expands because of θ. [ rise in temp.= θ]
