Question:
Anna is conducting an experiment to determine how weather affects cell phone reception. She is trying to decide the best way to conduct her experiment in order to collect meaningful data. Which of the following experiments would help Anna collect the best data? A. Test different cell phones in different locations on days with clear weather. B. Test different cell phones in different locations on days with rainy weather. C. Test a cell phone's reception in one location with clear weather and in another location with rainy weather. D. Test a cell phone's reception in the exact same location under various atmospheric conditions.
Answers
Answer:D. Test a cell phone's reception in the exact same location under various atmospheric conditionsExplanation:Components of an experiment:Independent variable:A manipulated variable, in an experiment or study, whose presence or degree incurs a change in the dependent variable.Dependent variable:A variable which is being studied in the experiment and is supposed to change with respect to the independent variable.Control variable:Control variable includes the variables which are of no concern in the experiment and must be constant so that they do not interfere with the results of the experiment. Change in control variable might affect the results of an experiment.In Anna's experiment, the independent variable is the atmospheric conditions. The dependent variable is cell phone reception that will change according to the atmospheric conditions. All other things related to the experiment are control variables like cellphone, location of the cell phone. Both of these must stay constant to collect the best data.Hence, the best option is D.
Answer:D. Test a cell phone's reception in the exact same location under various atmospheric conditions Explanation:

Assuming the mass of the ice in the beaker was 2000 g (2 kg), calculate the amount of heat that must have been added to convert the ice to water (assume that the entire 2000 g was ice at the start of melting, and the entire 2000 g was water at the end of the melting). Assume that the change took place entirely at 0 °C. The heat of fusion (DHfus) for H2O is 6.12 kJ/mol.
