Answer:
This question lacks options but it will be answered based on the fact that laboratory processes including heating are done using glasswares. The answer is:
Conical or Erlenmeyer/Boiling flask
Step-by-step explanation:
Glasswares are simply laboratory equipments made of glass. They are used in performing the various laboratory processes like mixing, storing chemicals, heating and cooling etc. Glasswares includes flasks e.g volumetric flask, Erlenmeyer flask etc, beaker, test tube, graduated cylinder etc.
Heating a liquid that would splatter or splash in a laboratory requires using a glassware that can prevent spilling of the liquid outside it. A FLASK such as Erlenmeyer or boiling flask is best suited for this purpose because they generally have a conical shaped body with a narrow neck that prevents liquid chemicals from spilling when heated or shaken. Flasks can also be corked with a lid to prevent the liquid from coming out.
