How do you measure room temperature using thermometer?
-- Bring thermometer into room. -- Wave it around in the air of the room for a minute or two. -- Do not hold the thermometer in your hand or breathe on it. -- Wait a while for the room temperature to get through the thermometer glass. -- Look through the glass at the sliver of liquid inside the thermometer. Find the end of the liquid, and see what number is marked on the glass at the same level. That number is your room temperature.
What metal element is used to make thermometers?
it is mercury. its actually a liquid at room temperature.
What does a max min thermometer do?
Mercury expands on heating.so at noon when the sun is overhead in the thermometer the Mercury expands and pushes the index down.And then the alcohol which is half filled in the maximum tube rises.then the max.temp is taken.
Why does the liquid level rise in a theremometer when the temperature is higher?
When the liquid is heated (by the environment), the particles in the liquid have more energy, and start moving around more, which causes the liquid to expand and take up more room. Conversely, in cold temperatures, the particles do not have as much energy, and do not move as much, so the liquid contracts.
The amount of water in the air compared to the amount the can hold is called?
The measure of the amount of liquid that a glass can hold is called its capacity or volume, and in most cases is measured in millilitres (ml) or ounces (oz.). The glass may have a measuring line inscribed on the side to indicate when it has been filled to this capacity, unless the glass is intended to be filled to the brim.
What is the the name of the object a thin glass tubbed filled with liquid that measures temperature?
Thermometer
What is liquid-in-glass thermometer?
what do they use for the liquid in glass ball thermometer
Which device has a liquid in glass components?
thermometer
Why are the thermometers called liquid in glass thermometers?
A so-called "glass" thermometer has a small bore-hole in the center of the glass that has some liquid in it. It's the activity of the liquid in the narrow hole that makes the thermometer a thermometer.
Which device has liquid in glass components?
thermometer
What are the four kinds of thermomether?
1. Alcohol or spirit thermometer 2. Mercury thermometer 3. Liquid crystal thermometer 4. Quartz thermometer 5. Reversing thermometer 6. Resistance thermometer
How does the thermometer used to measure air temperature differ from the thermometer used to take your temperature?
A thermometer used to measure air temperature uses a glass tube filled with a liquid either alcohol or mercury. When the temperature increases the particles of liquid expand, filling the glass tub. Thermometers that are used to measure you body temperature uses infrared sensors.
What are the materials in a thermometer?
For a classic thermometer: glass and mercury, colored ethanol or another liquid.
What was used to measure temperature before thermometers came out?
There was something called a Galileo thermometer that was completely different than the modern mercury thermometer. The Galileo thermometer is a glass cylinder filled with clear liquid in which a series of globes floats. The globes are filled with different colored liquid and have tags hanging on them with temperatures written on the tabs. You read it by looking to see which globes are floating and which are sinking.
How does a liquid in a glass thermometer?
the heat makes it expand you see
How does a glass thermometer works?
As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
What is a laboratory thermometer?
A laboratory thermometer is used to check the temperature, or changes in temperature, of an object with precise accuracy.
