What is the liquid in the thermometer called?
Mercury
the liquid inside thermometer is mercury.. but it is called thermometric liquid.Why does liquid in thermometer rise when you put the thermometer in a glass filled hot water?
Because that liquid in thermometer is actually a kind of metal called mercury (atomic symbol Hg). And like all metals it expand when heated. Hot water contains heat. --------------------------------------------- Because the liquid in the thermometer expands when it is warmed. As it expand it takes up more space and therefore rises up the measuring tube of the thermometer.There is liquid in some thermometer but, most have chemicals in it!!!!!!!!!!!
What change takes place in the liquid inside a thermometer when it is placed into somthing cold?
The liquid inside the thermometer "contracts" when it is placed into something cold. This means that it decreases in volume and increases in density. This is the reason that the thermometer can measure heat: the volume of the liquid inside the thermometer changes as a function of heat, and the amount of liquid in the "tube" of the thermometer changes as a function of volume. Because of this relationship, the level of the liquid in…
How do you use a celsius thermometer?
Place the thermometer in the liquid you are measuring. Wait until the temperature stabilizes, and then read the thermometer at eye level, just like you would a graduated cylinder, except that there's no meniscus. If you are measuring a liquid that is being heated over a Bunsen burner, you should have the thermometer held in place with a thermometer clamp. You should have the thermometer positioned about halfway down in the liquid.
Does the mass of liquid change if the volume of it changes?
The only way that the mass can change is if matter is added or taken away. The volume of a liquid can increase if heated, such as the liquid inside of a thermometer. The thermometer is sealed and no liquid gets in or out, so the mass of the liquid is unchanged. But when the temperature goes up, the liquid expands and is forced to go up the thermometer.
Why does the liquid in a thermometer sink down?
This liquid is sometimes colored alcohol but can also be a metallic liquid called mercury. Both mercury and alcohol grow bigger (expand) when heated and smaller (contract) when cooled. Inside the glass tube of a thermometer, the liquid has no place to go but up when the temperature is hot and down when the temperature is cold. Its the process of expansion and contraction
