Answer: 41 atmosphere

Explanation:

Given that:

Volume of water V = 0.5 L

(since 1 liter = 1dm3

0.5L = 0.5dm3)

Temperature T = 500K

Pressure P = ?

Number of moles of gas = 5 moles

Note that Molar gas constant R is a constant with a value of 0.0082 ATM dm3 K-1 mol-1

Then, apply ideal gas equation

pV = nRT

p x 0.5dm3 = 5 moles x (0.0082 atm dm3 K-1 mol-1 x 500K)

p x 0.5dm3 = 20.5 atm dm3

p = (20.5 atm dm3 / 0.5dm3)

p = 41 atm

Thus, the gas is under a pressure of 41 atmosphere

What is the relationship between the kinetic energy of molecules in an object and the object's temperature?
Natalija [7]

Answer: as the temperature increases, the kinetic energy of the molecules increases

Explanation: The kinetic energy of the molecules is the energy possessed by virtue of motion of the particles.

Kinetic energy of the particles is directly proportional to the temperature of the gas.

K.E=\frac{3RT}{2}

where T= temperature

R= gas constant

Thus if the temperature is increased, the molecules start moving more randomly and gain kinetic energy.
