An iron cube floats in a vessel containing mercury at 20^ C . If the temperature is increased by 100^ C , then the cube will float

Options

  1. Alower
  2. Bhigher
  3. Cat same level
  4. Dlower or higher depending on mass of cube

Correct answer

A. lower

Step-by-step solution

Lower (conceptual question). When temperature is increased, then the density will decrease, so cube will float lower.
