Question 8:
A piece of wood floats inside water at room temperature with a fraction of it above the liquid surface. As the temperature of the water is raised, the part of the wood above the liquid will
  • A Decrease because the density of water decreases with temperature
  • B Increase because the density of water decreases with temperature
  • C Decreases because the density of water increases with water temperature
  • D Increase because the density of water increases with temperature
