People use hot air balloons to rise high above the ground and be pushed by air currents from one place to another. The diagram shows a hot air balloon.
A type of chemical reaction, called combustion, takes place between propane and oxygen in the burners.
a. Describe a likely result of this chemical reaction that allows a hot air balloon to rise.
b. Describe a design feature the distance a hot air balloon can travel. Explain your reasoning.

Answers

Answer 1

Fueled by propane cylinders, gas jets produce the hot air that fills the envelope (similar to ones you might use on a portable camping stove).

WorkingSince heated air rises, hot air balloons are functional. with the rest. As though it were floating in water, the balloon rises as a result of this. The balloon naturally starts to slowly deflate if the air is allowed to cool.The molecules in the air start to migrate and spread out as the air within the balloon is heated, which results in a decrease in the air's density. The heated air is pushed below the cooler, surrounding air. the warm air is pushed upward as a result of this.

Answer:  He needs to hit the ball with less force.

Explanation:

hope this helps

1. Momentum = mass x velocity

2. Based off the answer to the first question, by hitting the ping pong ball, momentum is transferred from the boy to the ball. Causing the ball to have more velocity/speed and gain more momentum.

3. Momentum before = momentum after
Every time the ball hits the table, some momentum transfers from the ball to the table. Every time the player hits the ball, some momentum transfers from the player to the ball. This allows the player to continue playing ping pong as the ball always has momentum.
