TS EAMCET · Physics · Thermal Properties of Matter
Statement (I) : A device in which heat measurement can be made is called calorimeter. Statement (II) : Skating is possible on snow due to the formation of water below the skates. Water is formed due to the increase of temperature and ice melts. Statement (III) : Two bodies at different temperature are mixed in a calorimeter. Total internal energy of the two bodies remains conserved. Which of the following is correct?
- A Statements I, II and III are true
- B Statement I is true, but statements II and III are false
- C Both statements I and II are true, but statement III is false
- D Both statements I, III are true, but statement II is false
Answer & Solution
Correct Answer
(D) Both statements I, III are true, but statement II is false
Step-by-step Solution
Detailed explanation
While skating a person pressure the snow downwards with his weight due to which melting point of ice lowers and ice melt into water, which acts as a lubricant for skates. So, (II) is false. And, statement (I) and (II) are correct
