How does alcohol in a thermometer work?
Alcohol in a thermometer expands when heated and contracts when cooled. This change in volume causes the level of alcohol in the thermometer to rise or fall. By measuring the level of the alcohol, the temperature of the substance being measured can be determined.
What is the situation called when alcohol in the thermometer doesn't rise?
It is called a broken or non-functioning thermometer. This can happen due to a variety of factors such as a leak in the thermometer or issues with the alcohol solution inside.
A thermometer works on the principle that a rise in temperature causes?
A rise in temperature causes the particles in the thermometer to move faster, which in turn causes the liquid to expand and rise in the thermometer tube. This increase in volume is then calibrated to display a corresponding temperature reading.
What happens to the thermometer when the temperature goes up?
When the temperature goes up, the mercury or alcohol inside the thermometer expands, causing the level to rise. This increase in volume is directly correlated with the increase in temperature, allowing the thermometer to indicate the higher temperature.
What does an analog thermometer measure?
An analog thermometer measures temperature by using a liquid (like mercury or alcohol) that expands or contracts with changes in temperature, which causes the level to rise or fall in a narrow tube to display the temperature.
