Answer:

False

Explanation:

An atom itself is made up of three tiny kinds of particles called subatomic particles: protons, neutrons, and electrons. The protons and the neutrons make up the center of the atom called the nucleus and the electrons fly around above the nucleus in a small cloud.

Answer:

164atm

Explanation:

Given parameters:

Initial pressure = 150atm

Initial temperature = 27°C = 27 + 273 = 300K

New temperature = 55°C = 328K

Unknown:

New pressure = ?

Solution:

At constant volume, the pressure of a given gas varies directly with the absolute temperature.

Mathematically;

$\frac{P_{1} }{T_{1} }$ = $\frac{P_{2} }{T_{2} }$

P and T are pressure and temperature values

1 and 2 are the initial and new states

Insert the parameters and solve;

$\frac{150}{300}$ = $\frac{P_{2} }{328}$

300P₂ = 150 x 328

P₂ = 164atm
