Scientists often use containers to hold chemicals. A beaker can hold solids or liquids that won’t release gas and are unlikely to splatter if stirred or heated. A test tube is basically a smaller version of a beaker. It can hold small amounts of chemicals. If you’re worried about a substance splattering, an Erlenmeyer flask might be a good tool to use. Erlenmeyer flasks have a triangular shape to minimize splattering and spilling. To be extra safe about spills, you might use a stopper. However, never heat a container with a stopper on it! According to the passage, why is a substance in an Erlenmeyer flask less likely to spill than a substance in a beaker?

A
because Erlenmeyer flasks can never be heated

B
because Erlenmeyer flasks can only hold solid substances

C
because Erlenmeyer flasks hold smaller amounts of substances than beakers

D
because Erlenmeyer flasks have a triangular shape
