irinina [24]

Answer:

THE DISTANCE OF THE ROCK REFLECTING HER VOICE IS 82.5 METERS.

Explanation:

In sound waves, the speed of a sound is equal to twice the distance divided by time.

Mathematically,

Speed = 2 * Distance/ Time

Speed = 33- m/s

Time = 0.5 second

Distance = unknown

So re-arranging and introducing the variables into the formula, we have;

Distance = speed * time / 2

Distance = 330 * 0.5 / 2

Distance = 82.5 meters.

The distance away from the rock face which is reflecting her voice is 82.5 meters.

The volume of a gas is 1.15 L at STP. At what temperature would the volume of the gas increase to 1.56 L, if the pressure is dec

denis23 [38]

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.

<h3>What is an ideal gas?</h3>

An ideal gas is a gas whose behavior can be explained through ideal gas laws. One of them is the combined gas law.

A gas occupies 1.15 L (V₁) at STP (T₁ = 273,15 K and P₁ = 760 mmHg). We can calculate the temperature (T₂) at which V₂ = 1.56 L and P₂ = 650 mmHg, using the combined gas law.

$\frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2}\\T_2 = \frac{P_2 \times V_2 \times T_1}{P_1 \times V_1} = \frac{650mmHg \times 1.56 L \times 273.15K}{760mmHg \times 1.15 L} = 317 K$

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.
