Why in a clinical thermometer the bulb is not quite full of mercury at room temperature?

In a clinical thermometer, the bulb is not completely full of mercury at room temperature to allow for the expansion of the mercury when it is heated. This design ensures that the mercury can rise freely in the narrow capillary tube without any obstruction, providing an accurate reading of the temperature. Additionally, the small air pocket in the bulb prevents the mercury from spilling and enables it to return to its original position after the thermometer is removed from the heat source.


What are the procedures for taking temperature using 4 methods?

Oral method: Place the thermometer under the tongue for the recommended time. Axillary method: Position the thermometer in the armpit and hold the arm close to the body for a few minutes. Tympanic method: Gently insert the thermometer into the ear canal and follow the device's instructions. Rectal method: Lubricate the tip of the thermometer and insert it gently into the rectum for the appropriate duration.


What thermometer measures maximum and minimum pressure?

There is no special name for a maximum-minimum thermometer. It generally consists of two scales one will push a slider up as the temperature increases and the other thermometer pushes a slider down as the temperature goes down. You read it by observing the position of the sliders and then reset it so that the sliders return to the current temperature.


How does pressure affect a thermometer?

Heat is transferred thru the glass of the thermometer to or from the liquid (mercury) inside. The heat causes the liquid to either expand (hot) or contract. Since the large bulb end contains most of the liquid, but grass doesn't expand as much as the liquid, the expanding liquid forces itself up (if hot) into the narrow tube, which indicated the temperature. On the molecular level, particles outside the thermometer have a certain kinetic energy (KR) and the particles inside the thermometer also have a certain KE probably a different amount or they are already at the same temperature. Particles (either molecules or atoms) when in either the solid or liquid state, are constantly in motion (for solids, they just vibrate about a fixed, central position. Collision of the particles outside the thermometer and the thermometer itself cause exchange of some KE until the average KE of the outside particles is equal to the average KE of those in the thermometer. When this occurrs they are at the same temp. This change in KE of the particles in the thermometer causes more motion, and this extra motion causes what we call expansion. All molecules in the thermometer are pushing against each other with more force (KE).


How does cell differentiation and cell determination differ?

cell determination is closely linked to the position of the cells in the embryo. if the cells are surgically involved from the embryo and grown on, they will sitll produce the predetermined cell type as cell differentioation takes place to form tissue and organs, diffrent types of cell produce more an more proteins specific to their celll type
