Hari takes out a glass water bottle and a plastic water bottle kept overnight in the refrigerator. He instantly puts a thermometer on the walls of the plastic bottle and records the temperature as 10°C. What is the most likely temperature of the water glass bottle? Correct Answer almost equal to 10°C

Concept:

Temperature:

  • The temperature refers to the degree of hotness and coldness which decides the substance will supply or absorb heat from one another.
  • SI unit is Kalvin.
  • CGS unit is Celsius.

Thermal Conductivity:

  • It states that the amount of heat that flows through the face of solid material is directly proportional to the area of the cross-section, the temperature difference, and the period and inversely proportional to its thickness. 

Explanation:

  • In this case, plastic and glass bottles behave similarly because the lower thermal conductivity of plastic is offset by a thinner wall.

Thus, from the above discussion, we can say that the temperature of the water glass bottle is almost equal to 10oc.

Paddy transplantation in Punjab is a very hard labor-intensive back-breaking job. In the transplant season, teams of special people swarm the entire rural landscape employed by the farmers and can be seen laboring away in the fields under the hot sweltering sun. Farmer Jagtar Singh has a full-time help at his sprawling farm who goes by the name of Hari, and who hails from Allahabad, UP. During the paddy transplant season, it is up to Hari to rope in his brothers, sons, and cousins from his native village to complete the task well in time. All his people are skillful and masters of the trade and equally efficient at their jobs. So, this past season, this is how the work went. Hari started the work and after 't' hours was joined in by his brother Jaggi. After another 't' hours, Neelu, their cousin, also jumped into the fray. So, after every 't' hours, 1 person kept on joining the team of already working men, and this process kept on continuing till the completion of the work. The last person worked for 't' hours. In the last season, the very same men had completed the same work working 2 shifts of 12 hours all of them working simultaneously owing to some peculiar weather conditions and time constraints. Jagtar Singh is a fair and just paymaster which is why he faces no labor shortage at this crucial time and which is why the whole 'Hari clan' are more than happy to work for him and are at his beck and call. He pays each of them individually proportional to the work done by them. This time around, Hari received 11 times as much as Surinder, his eldest son, who was the last person to join in. In how much time was the work completed?
