When an alcohol thermometer is placed in
water, the thermometer will record temperature
.
Further explanation:
Temperature:
It is a physical quantity that measures the hotness or coldness of any substance. It is an intensive property. The device used to measure temperature is a thermometer. Three common scales are there to measure the temperature of a substance. These are the Celsius scale, Kelvin scale, and Fahrenheit scale. SI unit of temperature is Kelvin (K).
An alcohol thermometer is a substitute for mercury thermometers. It is an equipment that is used to measure the temperature of any object. The alcohol thermometer has less toxic contents as compared to those present in mercury thermometer.
Thermal expansion arises when there is change in the size and shape of the substance with a change in temperature.
Volume expansion occurs when a substance is expanded in three-dimensional space. The expression for volume expansion is as follows:
…… (1)
Here,
is the change in volume.
is the initial volume.
is the coefficient of volume expansion.
is the temperature change.
Rearrange equation (1) for
.
…… (2)
The change in temperature is inversely related to the coefficient of volume expansion. The value of
for mercury is
and that for alcohol is
. So the temperature recorded by the alcohol thermometer will be greater than
.
