Question

While working with heat in the laboratory, which of the following should you do?

A.
leave a flame or operating hot plate unattended

B.
point a heating container away from yourself

C.
reach across an open flame

D.
heat a liquid in a closed container

Answer 1

point a heating container away from yourself

Answer 2

I say it would be B. because it is the safest for you. You should never reach across a flame because of the risk of catching on fire. And never leave a flame unattended. Heating a liquid in a closed container could be dangerous as well because it heats fast and could go wrong. I hope this helps!
