Answer: The pressure will be 18.05 atm.

Explanation: Expression for ideal gas equation is :

PV=nRT

where,

P = Pressure of the gas = ? atm

V = Volume of the gas = 0.333L

n = Number of moles of gas = 0.250 moles

R = Universal gas constant = 0.082057\text{ L atm }mol^{-1}K^{-1}

T = temperature of the gas = 20°C = (273 + 20)K = 293K

Putting values in above equation, we get:

P\times 0.333L=0.250mol\times 0.082057\text{ L atm }mol^{-1}K^{-1}\times 293K

P = 18.05 atm

Answer:

<em>The correct option is A) The atom has changed over the years.</em>

Explanation:

Option A is not correct because an atom does not change. It remains the same always. The structure of an atom will always contain neutrons, protons and electrons.

Scientific theories tend to change over time as new information is brought up. Novel techniques lead to more advanced experiments and results. As a result, a scientific theory is subjected to change whenever evidence is found for a new theory which challenges the older one.

The atomic theory has changed many times due to novel scientific techniques and experiments.
