What mode of heat transfer is involved in the use of a thermometer?
Conduction is the main mode of heat transfer involved in using a thermometer. When the thermometer is placed in contact with a substance, heat transfers from the substance to the thermometer by conduction, causing the temperature to be measured.
What causes a thermometer to show a low temperature?
A thermometer may show a low temperature if it is exposed to a cold environment or if there is a decrease in the surrounding temperature that it is measuring. It could also show a low reading if the thermometer is placed incorrectly or is malfunctioning.
What happens to the mercury level when the cold thermometer is kept in a hot tub of water?
The mercury level in a thermometer placed in a hot tub of water will rise as the temperature of the water increases. This is because the volume of liquid mercury expands with higher temperatures, causing it to climb up the measuring scale in the thermometer.
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 the tube of the thermometer changes as a function of heat.

What is the most accurate method for measuring air temperature?
The most accurate method for measuring air temperature is using a high-quality digital thermometer placed in a shaded area away from direct sunlight and heat sources.
How is teampeture measured?
Temperature is typically measured using a thermometer, which can be digital or mercury-based. Temperature is usually recorded in units such as degrees Celsius or Fahrenheit. The thermometer is placed in the environment or substance being measured, and the reading on the thermometer indicates the temperature.
What change takes place in the liquid inside a thermometer when the thermometer is placed into something cold?
When a thermometer is placed into something cold, the liquid inside contracts and decreases in volume. This causes the liquid level to decrease, indicating a lower temperature on the scale of the thermometer.
How does an ear thermometer measure the temperature?
An ear thermometer measures temperature by detecting the infrared heat emitted by the eardrum and surrounding tissue. The eardrum shares blood supply with the hypothalamus in the brain, which regulates body temperature. By measuring this infrared heat, the ear thermometer provides an accurate estimation of core body temperature.
What happens to the mercury level when the cold thermometer is kept in a hot tub of water?
The mercury level in a thermometer placed in a hot tub of water will rise as the temperature of the water increases. This is because the volume of liquid mercury expands with higher temperatures, causing it to climb up the measuring scale in the thermometer.
Where is a thermometer normally placed in a house?
A thermostat for heating or a thermometer for air temperature is typically placed on an inside wall (not outside wall), and away from heating vents or direct sunlight.
How is accuracy of a thermometer improved?
A Thermometer's accuracy can be improved if it is placed in an area where there is not an object that touches it that can influence a temperature shift.

Why is a thermometer placed in a stevensons screen?
A thermometer is placed in a Stevenson screen to shield it from direct sunlight, precipitation, and other sources of heat or cold that could affect its accuracy. This allows the thermometer to provide a more precise measurement of air temperature.
