If Maria wants to have the best chance of blowing out all of the birthday candles on her birthday cake, she should bend down close to the candles, take a deep breath, make a small opening with her lips and then push her breath out. Why does doing it this way work the best?

A)It keeps the air she breathed in cool enough to put out the candle flames.
B) It makes the air come out with enough force to blow out the candle flames.
C)The air forms a blanket over the candles and pushes the candle flames down.
D)The air spins around when it comes out and hits all the candle flames this way.

Three things cause fire: fuel, oxygen, and heat. Remove one, the candle goes out.

By blowing in a constricted stream, you remove the heat from the wick, and it cools, and the fire is out. B is the best answer, but it is not as good as the above description.

thanks sooo much!

B) It makes the air come out with enough force to blow out the candle flames.

By bending down close to the candles and taking a deep breath, Maria is able to focus and concentrate a larger volume of air in her lungs. Making a small opening with her lips allows for better control of the airflow, and pushing her breath out generates a higher velocity of air. This increased force is essential in blowing out the candle flames.

The correct answer to this question is B) It makes the air come out with enough force to blow out the candle flames.

When Maria bends down close to the candles and takes a deep breath, she is able to inhale a larger volume of air into her lungs. This increases the amount of air available for her to exhale and blow out the candle flames. By making a small opening with her lips, Maria is able to direct the airflow and create a higher velocity of air coming out of her mouth. This increased airflow velocity creates more force, which is necessary to blow out the candle flames.

It is important to note that options A, C, and D are not correct because:

A) It keeps the air she breathed in cool enough to put out the candle flames: The temperature of the air Maria breathes in doesn't significantly affect her ability to blow out the candle flames. The force created by exhaling is the primary factor.

C) The air forms a blanket over the candles and pushes the candle flames down: While it is true that the air from Maria's breath forms a flow around the candles, it does not act like a blanket pushing down the flames. Instead, the force from the exhaled air blows out the flames.

D) The air spins around when it comes out and hits all the candle flames this way: The spinning motion of the air is not a significant factor in blowing out the candles. The primary force comes from the velocity of the air coming out of Maria's mouth.
