Class 6 Science Curiosity Temperature and its Measurement
If you are looking for Class 6 Science Curiosity Temperature and its Measurement solutions, then you are at the right place.
Q: What is temperature?
A: Temperature is a reliable measure of hotness (or coldness) of a body.
Q: What device is used to measure temperature?
A: A thermometer is used to measure temperature.
Q: What are the two main types of thermometers ?
A: Clinical thermometers and laboratory thermometers.
Q: What is the normal temperature of a healthy human body?
A: The normal temperature of a healthy human body is taken to be 37.0°C.
Q: What scale is commonly used in clinical thermometers?
A: Clinical thermometers generally use the Celsius scale.
Q: What is the unit of temperature on the Celsius scale?
A: The unit of temperature on the Celsius scale is degree Celsius, denoted by °C.
Q: What is the typical range of a laboratory thermometer?
A: The typical range of a laboratory thermometer is from -10°C to 110°C.
Q: What liquids are commonly used in laboratory thermometers?
A: Laboratory thermometers generally use alcohol (colored red) or mercury.
Q: Why is mercury being replaced by other substances in thermometers?
A: Mercury is being replaced because it is an extremely toxic substance and difficult to dispose of if the thermometer breaks accidentally.
Q: What is the Fahrenheit equivalent of 37.0°C?
A: 37.0°C is equivalent to 98.6°F on the Fahrenheit scale.
Q: What is the SI unit of temperature?
A: The SI unit of temperature is kelvin (K).
Q: How can you convert temperature from Celsius to Kelvin?
A: Temperature in Kelvin = Temperature in Celsius + 273.15
Q: Why should the thermometer be read while it is still immersed in the substance being measured?
A: The temperature should be read while the thermometer is immersed because the liquid column begins to fall as soon as it’s taken out.
Q: What precaution should be taken when placing a thermometer in water?
A: The bulb of the thermometer should not touch the bottom or sides of the container.
Q: What is the correct way to hold a thermometer while reading it?
A: The thermometer should be held vertically, and the eye should be directly in line with the level of the liquid column.
Q: What happens to the temperature of water while it’s boiling?
A: The temperature of water remains constant while it is boiling.
Q: What happens to the temperature of ice while it’s melting?
A: The temperature of ice remains constant while it is melting.
Q: What is a room thermometer used for?
A: A room thermometer gives an approximate idea of the room temperature.
Q: Who was known as the ‘Weather Woman of India’?
A: Anna Mani was known as the ‘Weather Woman of India’.
Q: Why can’t a laboratory thermometer be used to measure body temperature?
A: A laboratory thermometer can’t be used to measure body temperature because its range is typically from -10°C to 110°C, which is too wide for precise body temperature measurements.
