Which statement describes how an atom in the ground state becomes excited

Marysya12 [62]

The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron. ... An electron can become excited if it is given extra energy, such as if it absorbs a photon, or packet of light, or collides with a nearby atom or particle. (I do not take credit for that answer)

A sample of gas occupies 10 L at STP. What

puteri [66]

Pressure is 5.7 atm

Explanation:

P1 = Standard pressure = 1 atm

P2 = ?

V1 = Volume = 10L

V2= 2.4L

T1 = 0°C + 273 K = 273 K

T2 = 100°C + 273 K = 373 K

We have to find the pressure of the gas, by using the gas formula as,

$$\frac{P 1 V 1}{T 1}=\frac{P 2 V 2}{T 2}$

P2 can be found by rewriting the above expression as,

$$P 2=\frac{P 1 \times V 1 \times T 2}{T 1 \times V 2}$

Plugin the above values as,

$$P 2=\frac{1 \text {atm} \times 10 L \times 373 \mathrm{K}}{273 \mathrm{K} \times 2.4 \mathrm{L}}=5.7 \text { atm }$
