Question

identifying the relationship between type of material and thermal energy transfer
energy transferred for 50g of material
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:

• For the first option: Lead has the lowest bar (energy transferred) among the four materials. Since specific heat \(c=\frac{Q}{m\Delta T}\) (where \(Q\) is energy transferred, \(m\) is mass, \(\Delta T\) is temperature change), for same \(m\) and \(\Delta T\), lower \(Q\) means lower \(c\). So this option is wrong.
• For the second option: Inverse proportionality would mean \(Q\times material - related - factor=constant\). But from the bar - chart, there is no such pattern (e.g., no mathematical inverse - product relationship between energy transferred and a property inherent to the material type).
• For the third option: The bar - chart shows different heights (different energy transferred values) for different materials (sand, aluminum, steel, lead) when mass (\(m = 50g\)) is the same. This implies different materials have different abilities to transfer energy (as \(Q\) (energy transferred) is different for same \(m\) and same experimental setup for heat transfer).
• For the fourth option: The mass is kept constant (\(m = 50g\) for all materials). So there is no proportionality (which would require a change in mass and a corresponding change in a variable related to the material) shown in the chart.

Answer:

Different materials have different abilities to transfer energy.
