The bulb of a thermometer is usually made of glass to allow for expansion and contraction of the liquid inside. When the thermometer is subject to sudden changes in temperature, the glass can crack or shatter due to thermal stress, causing the bulb to break.
If you hold a mercury thermometer from its bulb, the heat from your hand can cause the mercury to expand and rise in the tube, giving an inaccurate reading. Additionally, mercury is toxic, so it is not safe to handle a broken thermometer. Always handle thermometers by the plastic casing to avoid these issues.
The wet bulb thermometer is typically read lower than the dry bulb thermometer because the evaporation of water on the wet bulb cools the sensor by removing heat from it. This process is known as evaporative cooling and results in a lower temperature reading on the wet bulb thermometer compared to the dry bulb thermometer.
A psychrometer has two thermometers: a wet bulb thermometer and a dry bulb thermometer. It is used to measure relative humidity and can also determine dew point.
The wet bulb temperature is always lower than the dry bulb temperature. The wet bulb temperature is the temperature taken by a thermometer covered in a wet cloth and exposed to moving air, and it reflects the evaporative cooling effect.
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
No, the wet bulb is always lower. Evaporation from the wet bulb reduces its temperature.
The bulb of a clinical thermometer breaks when placed in very hot water because the sudden increase in temperature causes the air inside the bulb to expand rapidly. This rapid expansion of air creates pressure within the bulb, leading to its breakage.
