The following are some common procedures that we should take action of when using a bunsen burner to ensure our safety:
1. Wear safety goggles. Tie up long hair and school ties if needed. This can lower the risk of catching on fire. Put a heatproof mat underneath the Bunsen burner, put a tripod and the beaker of water for heating on top of the burner.
2. Close the air hole. Before we start up the burner, the air hole must be closed or green flame (striking back) may occur
3. light up a match or a lighter. Put it over the chimney.
4. Turn on the gas tap, you should be able to see a yellow flame now. Remove the lighter or match and open the air hole. We should have a blue flame by now.
5. the water should start to heat up. Never touch the hot beaker with bare hands.
6. When the water is heated up to the temperature they wanted to, it's time to close the air hole and turn off the gas tap.
7. If they need to move the hot beaker, use heat protection gloves
These should be the correct procedures that they should follow in order to heat the water safely.
Hope it helps!
It would require frequent rainfall. It cannot survive on dry land without constant water.
Answer:
Fossils are the preserved remains or traces of animals, plants, and other organisms from the past. Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today
Explanation:
The given blank can be filled with a feature resulting from hot volcanic rock.
The geysers refer to the rare characteristics on Earth, only about 1000 of them prevail, and more than half of those are situated in Yellowstone. For a geyser to develop, there must be a source of volcanic heat, enough groundwater, and a geologic plumbing system via which the heated water can escape.
The absconding of water takes place when the groundwater is heated by the hot volcanic rocks. The intensifying steam bubbles push the water above via the fissures in the rock until they overflow from the geyser.
With the absconding of the top layers of the water, the pressure on the hotter waters below diminishes, leading to a violent chain reaction of explosions, which expand the volume of the rising boiling water by up to 1500 times or more.
