In the light spectrum, the photons with a higher frequency (hence smaller wavelengths) have higher energy. The lower the energy the lower the frequency and longer the wavelengths. The intensity of light does not change the energy levels of these photons. The higher the intensity the higher the density of the photoelectrons.

In the mathematical equation showing that volume (V) divided by temperature (T) remains equal to a constant (k), volume and temp

NARA [144]

Answer:

Directly

Explanation:

$\dfrac{V}{T} = k$

If V increases, then T must also increase to keep the same ratio.

If V decreases, then T must also decrease to keep the same ratio.

V and T are directly proportional, because a change in one always causes a change in the other and the changes are in the same ratio. The constant k is called the proportionality constant.

A sample of Hydrogen gas has a volume of 25.5 liters at a pressure of 15.0 kPa. If the temperature is kept constant and the pres

patriot [66]

Answer:

<h2>7.65 litres </h2>

Explanation:

The new volume can be found by using the formula for Boyle's law which is

$P_1V_1 = P_2V_2$

Since we're finding the new volume

$V_2 = \frac{P_1V_1}{P_2} \\$

15 kPa = 15,000 Pa

50 kPa = 50,000 Pa

We have

$V_2 = \frac{15000 \times 25.5}{50000} = \frac{382500}{50000} \\ = 7.65$

We have the final answer as

<h3>7.65 litres </h3>

Hope this helps you
