First steps to using a Bunsen burner:

• Place on heat proof mat, connect gas hose to a gas tap and make sure the air hole is closed

• Place on heat proof mat, connect gas hose to a gas tap and make sure the air hole is open

• Place on heat proof mat, connect gas hose to a gas tap and light the Bunsen burner

Air hole closed means __________ safety flame and air hole open means _________ heating flame.

• Yellow, blue

• Blue, yellow

• Blue, orange

• Yellow, green

During an experiment, a Bunsen burner is placed on:

• Gauze mat

• Tripod

• Heatproof mat

• Science bench

When heating a test tube you.....

• Wear safety goggles, use a test tube holder and hold the test tube away from you

• Wear safety goggles, use tongs and hold the test tube close to you

• Wear safety goggles, use a test tube holder and make sure the flame is only yellow

The different parts of a bunsen burner include:

• Barrel, collar, air hole, gas hose and base

• Barrel, collar, air vent, gase hose and base

• Barrel, collar, air vent, gas hose and bottom

• Barrel, neck, air hole, gas hose and base

When you lift a bunsen burner, you hold it from the:

• Barrel

• Gas hose

• Base

• Collar

When you first light a bunsen burner, the flame should be:

• Yellow

• Blue

• Either

• Non existent. You shouldn't be using a bunsen burner to light things in the lab
