When hot water is sprinkled on a thick glass, the sudden temperature change causes the glass to expand rapidly. This expansion creates stress within the glass, which can exceed its tensile strength, leading to breakage. Therefore, the sudden expansion of ...

As water cools from 10°C to 0°C, its density decreases until it reaches 4°C, where it is at its minimum. Below 4°C, water begins to expand as it approaches the freezing point, causing its density to increase again. Therefore, the ...
In summer, the heat causes rubber to harden, reducing its flexibility. As a result, when air inside the bicycle tube expands due to the heat, the hardened rubber cannot adequately accommodate the increased pressure. This leads to increased stress on ...
When a glass rod is exposed to steam, its length increases due to thermal expansion, while its width remains unaffected. Glass primarily expands in the direction of the applied heat, elongating along its length. However, its width does not experience ...
When the solid metal ball is heated, the particles inside it gain kinetic energy, causing them to move more vigorously, leading to expansion. This expansion includes the volume of the cavity inside the ball, resulting in an increase in its ...
When a bottle is filled with water and allowed to freeze, the bottle breaks because water expands as it freezes, exerting pressure on the walls of the bottle. This expansion exceeds the tensile strength of the bottle material, causing it ...
In cold countries, alcohol is preferred over mercury as a thermometer liquid because the melting point of alcohol can be lower. This ensures that alcohol remains liquid at lower temperatures, making it effective for use in cold climates where mercury ...
Thermocouples are made by two dissimilar metals. When these metals are joined at both ends, a voltage is generated when there is a temperature difference between the junctions. This voltage can be measured and used to determine the temperature.
Radiation pyrometers measure temperatures above 800°C. These instruments detect thermal radiation emitted by an object and convert it into a temperature reading. They are commonly used in high-temperature industrial processes such as metalworking, ceramics, and glass manufacturing, where temperatures exceed ...
On the Celsius scale of temperature, absolute zero temperature is -273.15°C. Absolute zero is the lowest possible temperature where particles of matter have minimal thermal motion, theoretically reaching a state of complete rest. It serves as the zero point for ...
