Answer :
Final answer:
The two pieces of equipment used for heating substances in a laboratory are the Bunsen Burner and the Hot Plate. Both tools serve different heating needs, with the Bunsen burner providing rapid direct heat and the hot plate allowing for a flame-free heating method. Beakers and test tubes are used to hold substances but do not generate heat themselves.
Explanation:
Equipment Used to Heat Substances
In a laboratory setting, certain pieces of equipment are specifically designed to heat substances. Among the options provided, the two that are primarily used for heating are:
- Bunsen Burner: This is a common piece of equipment in many labs. It uses a flame produced by the combustion of gas to provide a rapid heat source. It is particularly useful for heating small amounts of substances in test tubes or beakers.
- Hot Plate: This is another versatile piece of equipment. It can heat beakers and Erlenmeyer flasks effectively, making it suitable for both simmering liquids and boiling substances. It is often preferred for heating larger volumes or when a flame-free method is needed.
Other equipment listed, such as beakers and test tubes, are used to contain substances during heating but do not produce heat themselves.
