Question

examples of solid expansion in our daily life

Answer 1

जैसे ट्रेन की पटरी or बरसात के दिनों में दरवाजों का बढ़ जाना

Answer 2

Most liquids follow a fairly predictable pattern of gradual volume increase, as a response to an increase in temperature, and volume decrease, in response to a decrease in temperature. Indeed, the coefficient of volume expansion for a liquid generally tends to be higher than for a solid, and—with one notable exception discussed below—a liquid will contract when frozen.
