A student wants to measure the temperature change of water after adding a 10 cm3 block of iron to container 1 and a 10 cm3 block of lead to container 2. Both blocks were heated to 40°C before being added to the water. The image below shows the experiment immediately after adding the blocks. Why did the temperature increase more for container 1 even though each 10 cm3 block was heated to 40°C and placed in 100 mL of water at 25°C? A. Different materials can have different rates of sinking. B. Different materials can have different densities. C. Different materials can have different rates of dissolving. D. Different materials can have different capabilities of transferring heat.

98 points you will be galileo perform the experiment to determine if objects with different mass fall at the same, or different, rates in the air and in a vacuum. before you conduct your experiment, you need to form a hypothesis. a hypothesis is a prediction of what you think will happen in the experiment. the hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. record your hypothesis here: record the results from step one of the experiment (dropping the objects in the air): first trial: second trial: third trial: record the results from step two of the experiment (dropping the objects in a vacuum): first trial: second trial: third trial: did the experiment support your hypothesis? using the data from your experiment, describe why you believe your hypothesis was either proven or disproven. what forces were acting on the objects dropped in the air? what force was acting on the objects dropped in the vacuum? part two: comparing forces choose two forces and compare and contrast these forces. you must provide two ways that they are alike and two ways that they are different. you may make a list, write in paragraph form, or make a chart. choose two forces and compare and contrast these forces. these must be different forces than used in the prior question. provide two ways that they are similar and two ways that they are different. you may make a list, write it out, or make a chart.
