CAPE UNIT 1 PHYSICS : MODULE 3 Flashcards - Quizlet In this type of thermometer, the pressure of a fixed mass of gas is measured using a mercury nanometer The glass bulb holds a fixed volume of gas In order to ensure that the volume of the gas remains constant, the height of the movable tube is adjusted so that the mercury is always at the fixed volume marker
Thermo Thursday: chapter 1. 1 - Eugene Fischer (a) Get a mercury thermometer, No estimate the size of the bulb at the bottom, and then estimate what the inside diameter of the tube has to be in order for the thermometer to work as required
Thermometers with Mercury: Everything You Need to Know In this blog post, we will delve into the fascinating history of thermometers with mercury and explore why there is an increasing shift towards safer, mercury free alternatives As we begin, we will examine mercury’s unique properties that made it ideal for measuring temperature
Where does mercury in thermometers come from? - Answers Digital thermometers use electronic sensors to measure temperature and display it on a screen, while mercury thermometers contain mercury that expands or contracts with temperature
How Does a Thermometer Work? The Hidden Science Inside a . . . A thermometer works because of a simple yet fascinating scientific principle: liquid expansion and contraction 🌊🔍📏 The liquid inside a thermometer, usually mercury or alcohol, reacts to temperature changes
1. 1 Thermal Equilibrium — Real Physics documentation Why do thermometers work? In a mercury thermometer, temperature changes the mercury such that it either expands or contracts You are really seeing how big the mercury is, and inferring from that the temperature
Heat: 7th Class NCERT CBSE Science Chapter 04 Question: Instead of water explain the reason, why do the mercury is used in the thermometer? Answer: Due to following reasons, mercury is used in the thermometers instead of water When the thermometer breaks, the mercury can be easily collected Mercury can has more expansion than the water
