Answer is the ideal gas law
Answer:
16 cm
Explanation:
Because when you look at the ruler, it shows the length as 16 cm
The volume of the air mattress in litres is 385 litres when absolute pressure was 3.5 kilopascals.
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Given data:
P= 3.5 kPa
V=?
n= 0.55 moles of air
T= 295K
R= 8.314 (L kPa/mol K)
We use the constant rate of 8.314 because we are using kilopascals in this problem.
Using the equation:
PV=nRT,
V =
V = 385.4132857 L.
Hence, the volume of the air mattress in litres is 385 litres.

In his experiment, Thompson shot a beam of alpha particles at a sheet of gold foil<span>, and only a few of the particles were deflected or reflected right back. Before the experiment, the plum pudding model was believed to be true, where a cloud of positive ions distributed throughout the inner space of an atom. Thompson concluded that there's a high-energy dense nucleus at the center of an atom.</span>
