question

The instructions below outline the procedure for a demonstration. Materials: four 100 g metal blocks, each of a different metal four polystyrene foam cups, each containing 150 g of 10°C water Procedure: 1. Place the four cups of water next to each other on the lab bench. 2. Heat each block to a temperature of 60°C. 3. Place each heated block in a separate cup of 10°C water. 4. Measure the temperature change in each cup of water after 100 s. At the end of the demonstration, which block raised the temperature of the 10°C water the greatest amount?

choices

  • the block with the greatest density
  • the block with the lowest surface area
  • the block with the greatest specific heat
  • the block with the lowest thermal conductivity
