Sumit takes out water in a beaker from a bucket for an experiment. He puts the thermometer in the water in beaker and notes the reading as 35°C. Which of the following conclusions drawn by him are correct? A. The temperature of water in beaker and bucket are almost same. B. The heat in water in beaker and bucket are same C. The temperature of water in beaker is less than the temperature of water in bucket. D. The heat in water in bucket is more than the heat in water in beaker Correct Answer A and B

Concept: 

  • When heat is absorbed or lost by the system leads to a change in temperature.
  • Change in temperature due to heat transfer is measured by a thermometer.
  • Temperature is an intensive property 
  • It does not depend on the amount of substance

Explanation: 

  • As we know temperature is an intensive property so it will not change by transferring some amount of it into another vessel.
  • Heat is transferred through the material in three forms
    • Conduction
    • Convection
    • Radiation 
  • But in this problem we have not provided heat externally, so, heat will not be transferred by any of these forms.
  • Therefore, the temperature of water in the beaker and bucket are almost the same.

Additional Information

  •  Heat is a form of energy.
  • Heat flows from an object which is at a higher temperature to a body of lower temperature or from a hotter body to a colder one.
  • Heat continues to flow until the heat content of the two bodies becomes equal.
  • At this point, the temperature of the two bodies is the same and they have reached thermal equilibrium.
