You are planning an investigation to compare the mass of a gas (air) and a liquid (water). How would you design the experiment to collect data on the mass of both substances?
A. Use a balance to measure the weight of air in an open container and water in a sealed container, then compare the readings.
B. Measure the volume of air and water using a thermometer, then calculate their mass.
C. Use a thermometer to measure the temperature of the air and water, then measure their volume to calculate the mass.
D. Use a balance to measure the mass of the liquid water and use a scale to measure the volume of the air.
A. Use a balance to measure the weight of air in an open container and water in a sealed container, then compare the readings.
If you were to create a plan for an experiment to determine if different liquids have the same mass at the same temperature, which combination of materials and equipment would you use?
