7.むずかしい

Equal masses of sand and water sit in the sun and absorb the same amount of heat. Which warms up more, and why?

  1. ASand, because it has a higher specific heat capacity than water
  2. BSand, because it has a lower specific heat capacity than water
  3. CWater, because it has a higher specific heat capacity than sand
  4. DBoth warm equally, because they absorbed the same heat
8.むずかしい
