PhysicsMediumassertion reason
Assertion: In rigid nonexpanding open vessels, water initially at 4°C rises in level both when warmed to 10°C and cooled to 1°C, with no evaporation. Reason: At ordinary pressure water has maximum density near 4°C.
Options:
Answer:
A
Solution:
Mass is fixed. Density decreases away from its maximum near 4°C on either side, so volume increases. A rigid vessel then shows a higher level. Both true, with the stated explanation.
