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).
the thermometer that works on constant pressure
You need two tools. To measure the air pressure you use a barometer and to measure the temperature at which the substance boils you use a thermometer. The boiling point is defined as the temperature at which the vapor pressure equals atmospheric pressure.
Doug will need a pressure gauge to measure the pressure of the gas, a temperature gauge to measure the temperature of the gas, and a container to hold the gas while adjusting the pressure.
A vapor pressure thermometer is a device that measures temperature by detecting the pressure of a vapor in a closed chamber. As temperature increases, the pressure of the vapor also rises, allowing for temperature measurement. These thermometers are often used in scientific and industrial applications where precise temperature control is necessary.
No, it is not safe to use rubbing alcohol in a simple thermometer. Rubbing alcohol is a disinfectant and can affect the accuracy of the thermometer readings. It is recommended to use a thermometer as per the manufacturer's instructions.

No a barometer does a thermometer measures temperature
You asked the question wrong. The analogy was : Thermometer is to Temperature as Barometer is to Air Pressure.A meteorologist uses his Barometer to measure pressure in millibars, very small changes in the atmosphere's pressure. He uses the Thermometer to measure the air Temperature.
a barometer is used to measure the air pressure, not a thermometer! A thermometer is used to measure the temperature.

Yes, using a cold thermometer can affect the temperature reading by causing it to start at a lower baseline. It's important to ensure the thermometer is at room temperature before use to get an accurate reading.

A vapor pressure thermometer is a device that measures temperature by detecting the pressure of a vapor in a closed chamber. As temperature increases, the pressure of the vapor also rises, allowing for temperature measurement. These thermometers are often used in scientific and industrial applications where precise temperature control is necessary.
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.
No, it is not safe to use rubbing alcohol in a simple thermometer. Rubbing alcohol is a disinfectant and can affect the accuracy of the thermometer readings. It is recommended to use a thermometer as per the manufacturer's instructions.
No, it is not recommended to leave the thermometer in the meat while cooking as it can affect the accuracy of the temperature reading.
