Guida verificata passo dopo passo1
Understand the purpose of each laboratory instrument listed: an Analytical balance is used to measure mass, a Bunsen burner is used to heat substances, a Beaker is used to hold and roughly measure liquid volumes, and a Desiccator is used to keep substances dry.
Recall that estimating the volume of a liquid requires an instrument that can contain and allow for volume measurement, even if approximate.
Recognize that an Analytical balance measures mass, not volume, so it is not suitable for estimating liquid volume.
Note that a Bunsen burner is a heat source and does not measure volume.
Conclude that among the options, a Beaker is the most appropriate instrument for estimating the volume of a liquid because it is designed to hold liquids and has volume markings for approximate measurement.
