NEET · Physics · Thermal Properties of Matter
Statement (I) : A device in which heat measurement can be made is...
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?
Options
- AStatements I, II and III are true
- BStatement I is true, but statements II and III are false
- CBoth statements I and II are true, but statement III is false
- DBoth statements I, III are true, but statement II is false
Correct answer
D. Both statements I, III are true, but statement II is false
Step-by-step solution
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
