In a country with a cold climate, a bicycle has been kept outdoors overnight. The cyclist notices that the plastic hand grips feel less cold to the touch than the steel handlebars. Which row correctly states the temperature and the property of the two materials?

  • Athe temperature of the steel is much lower than that of the plastic; the plastic is a better thermal conductor than the steel
  • Bthe temperature of the steel is much lower than that of the plastic; the steel is a better thermal conductor than the plastic
  • Cthe steel and the plastic are both at the same temperature; the plastic is a better thermal conductor than the steel
  • Dthe steel and the plastic are both at the same temperature; the steel is a better thermal conductor than the plastic
