Step 1
What is meant by the temperature of a body?
Answer
The temperature of a body is a measure of its hotness or coldness. It quantifies the amount of thermal energy present, which corresponds to the average kinetic energy of the particles within the substance. A higher temperature indicates greater energy and faster-moving particles, while a lower temperature signifies reduced energy and slower particle movement.

Step 4
The diagram shows a laboratory thermometer, what is its thermometric property?
Answer
The thermometric property of the laboratory thermometer is its length, which varies with temperature changes. As the temperature increases, the liquid inside the bulb expands and rises in the capillary tube, providing a measure of temperature based on the length of the liquid column.

Step 6
Why is there a need for a standard thermometer?
Answer
There is a need for a standard thermometer because different thermometers can measure temperature differently and yield varying results. A standard thermometer ensures consistency and accuracy for calibration purposes, allowing for reliable comparisons in scientific and industrial applications.
