The independent variables in Part I, the ones intentionally manipulated, are the [___].
The independent variable in Part II, the one that is intentionally manipulated, is the [___].
The dependent variable for both Parts I and II, the one that you measure the response in, is the [___].
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?
Which material has the highest specific heat? [___]
Which are potential sources of error in the experiment? Check all that apply.estimating temperature to the nearest tenth of a degreeestimating the mass of the sample to the nearest tenth of a gramestimating the thickness of the foam cupsthe position of the cups of sand and water under the heat lampthe brand of light bulb used for the heat lampthe air temperature outside the lab
Which are ways to improve the design of this experiment? Check all that apply.Reduce the sample size so the experiment can be done faster.Increase the sample size from 6 cups to 12 cups of sand and water.Use more legible handwriting when recording data.Use more precise digital thermometers.Use more precise scales that measure to the hundredth of a gram.
The unit often used in chemistry and physics to measure energy, such as for work or electrical current, is the [___]. We can also use this unit, as we did in this lab, for measuring [___]. This is a property that is quantified by the energy needed per [___] of material to raise the temperature by one [___]. The unit for this measure is therefore [___].
Which material has the lowest specific heat? [___]
[___]
