This may be a better way to ask this...
When pouring Nutrient agar into Petri plates, the procedure instructs you to keep the covers slightly ajar. Explain why the plates don't get contaminated from organisms suspended in the air?
Inoculation is the process were in you will introduce bacterial samples on a nutrient broth or nutrient agar. If the medium you use contain bacteria it is now called inoculum. there are different technique in introducing bacteria in the medium like streaking, spreading, pouring.
To pour a liquid properly, hold the container steadily with one hand and tilt it slightly. With the other hand, guide the liquid to control the flow. Pour smoothly and steadily to avoid spilling, and adjust the angle of tilt to control the speed of pouring as needed.
Why we cool agar before pouring depends on WHY we are pouring it. If we are pouring a gel or standard media for streak culture then we allow some cooling to take place because we don't want to burn our fingers. If we are pouring a pour plate we allow a lot of cooling to take place so we don't kill our microbes through heat steralization. As my teacher used to say "boiled bugs don't grow".
No, pouring water into a glass is not an example of momentum. Momentum is the product of an object's mass and velocity, and pouring water into a glass does not involve a specific object moving with velocity.
Decantation usually refers to pouring liquid. It can be just pouring liquid from one container to another, or removing the liquid from a solid sediment by pouring the liquid off and leaving the solid behind.

To improve your saucering technique when pouring coffee, try pouring the coffee slowly and steadily into the saucer to prevent spills. Practice tilting the saucer slightly to control the flow of the coffee. Additionally, focus on maintaining a steady hand and a consistent pouring motion to achieve a smooth saucering experience.
Human waste contains many different bacteria, and bacteria such as cholera happily grow on human feces. Industrial waste contains heavy metals, which can poison the ground where the water meets it and they can also be dispersed via the air.
It is with salt or vinegar that homemade weed-killer tends to be made. The salt may be either diluted for pouring or spraying or sprinkled while the white distilled vinegar is diluted heavily or slightly for pouring or spraying the ground.

the boy is pouring water away the rain is pouring down
I'm assuming you want the phrase "pouring in" and not just the word "pouring." Rain is pouring in through the hole in the roof. Whenever she takes over a company, money just starts pouring in.
To properly dispose of coffee grounds, you can compost them to create nutrient-rich soil for plants, or you can dispose of them in the trash. Avoid pouring them down the sink as they can clog the drains.
The rain is not pouring down.
Yes, as in pouring a cup of tea.
