Frequent question: How do you measure the temperature of boiling water?

Contents

Which thermometer do you prefer to measure the temperature of boiling water between a clinical or a laboratory thermometer and why?

Clinical thermometer generally is used for measuring body temperature which is not as high as 100 degree. Therefore it does extend to the readings for such high temp. For measuring the temperature of boiling water we have to use a lab thermometer.

What happens to the temperature of water while it is boiling?

When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. … Therefore the temperature of the liquid remains constant during boiling. For example, water will remain at 100ºC while boiling.

Which thermometer can be used to measure boiling water?

A Celsius thermometer will measure the boiling point of water at 100° and its freezing point at 0°; a Fahrenheit thermometer will measure the same events at 212° for the boiling point of water and 32° as its freezing point.

Can we use digital thermometer to measure boiling water?

Q23) Can a clinical thermometer be used to measure the temperature of the boiling water ? Give reason for your answer. Solution : No, a clinical thermometer cannot be used to measure the temperature of boiling water because it has a small range and might break due to extreme heat.

Why we Cannot use alcohol thermometer to measure boiling water?

The contents of alcohol are less toxic and will evaporate quickly as compared to the mercury-in-glass thermometer. Since, alcohol starts boiling at 80℃ while the boiling point of mercury is 375℃. … Therefore, No alcohol thermometer cannot be used to measure the temperature of boiling water.

Which cools faster water or soil?

It takes less energy to change the temperature of land compared to water. This means that land heats and cools more quickly than water and this difference affects the climate of different areas on Earth. … Earth’s oceans are far more important than the land as a source of the heat energy which drives weather and climate.

What is Class 9 boiling point?

Hint: The temperature at which conversion of liquid on heating takes place at standard atmospheric pressure is called the boiling point of that liquid and the phenomenon is called boiling. Complete step by step solution: … Pure water at standard pressure (1atm) boils at 100∘C.

Why should a clinical thermometer not be washed in hot water?

A clinical thermometer should not be washed in hot water, because it will break up. Explanation: Clinical thermometer is used to measure the temperature 95 to 105F (35°C to 42°C). It is used to read the temperature of human and animals.

What’s the normal range for body temperature?

The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the “normal” body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most often means you have a fever caused by an infection or illness.

Why it is not advisable to wash the clinical thermometer with hot water?

Answer: Because you will break it. The clinical thermometer has been made to measure temperature around our physiological temperature or 95 to 105F (35 to 40C. Using it in boiling water would break it, going way past the max temperature for this thermometer.
