Question

in an experiment, 50 g of each material were placed in a calorimeter with the same starting water volume and temperature. which is the best interpretation of the chart? lead has the highest specific heat of the four materials shown. the energy transferred and type of material are inversely proportional to each other. different materials have different abilities to transfer energy. mass and type of material are proportional.

Explanation:

• Specific heat is related to the amount of energy required to change a material's temperature. Lead transferred the least energy, so it does not have the highest specific heat.
• Inverse proportionality would mean as one variable increases, the other decreases in a specific mathematical way. The chart does not show a clear inverse proportionality relationship.
• The chart shows different materials (sand, aluminum, steel, lead) transfer different amounts of energy (4 J, 5 J, 3 J, 1 J respectively). This indicates different materials have different energy - transfer abilities.
• The mass of each material is the same (50g), so there is no indication of a proportional relationship between mass and type of material.

Answer:

Different materials have different abilities to transfer energy.
