gas has a volume of 185 ml and pressure of 310 mm hg. The desiered volume is 74.0 ml. What is the required new pressure

Answers

Answer 1

Answer:

Answer:

The required new pressure is 775 mm hg.

Explanation:

We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.

We have to find the required new pressure.

Let the required new pressure be ' $\text{P}_2$ '.

As we know that Boyle's law formula states that;

$P_1 * V_1 = P_2 * V_2$

where, $P_1$ = original pressure of gas in the container = 310 mm hg

$P_2$ = required new pressure

$V_1$ = volume of gas in the container = 185 ml

$V_2$ = desired new volume of the gas = 74 ml

So, $P_2 = (P_1 * V_1)/(V_2)$

$P_2 = (310 * 185)/(74)$

= 775 mm hg

Hence, the required new pressure is 775 mm hg.

Why a soccer ball that is quickly rolling across a grass field slows and finally stops rolling

Answers

friction accord while the ball was rolling in the grass and slowed it down until it finally came to a stop

This is because of friction. If you want to add extra detail you can say that this ties in with Newton's First Law of Motion, which states that an object moving at a constant speed will stay moving at a constant speed unless there is an opposite force, and in this case, the opposite force against the ball is friction.

What happens in a change in temperature as it is heated

Answers

It increases in temperature

Please I need help on this

Answers

Answer: Generally, prevailing winds blow east-west rather than north-south. This happens because Earth's rotation generates what is known as the Coriolis effect. The Coriolis effect makes wind systems twist counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere.
