<u>Answer:</u> The new pressure will be 1.69 atm
<u>Explanation:</u>
Gay-Lussac's law states that the pressure of the gas is directly proportional to the temperature of the gas at constant volume and the number of moles.
Mathematically,
(At constant volume and number of moles)
OR
.....(1)
are the pressure and temperature of the gas
are the final pressure and temperature of the gas
We are given:
Putting values in equation 1, we get:
Hence, the new pressure will be 1.69 atm
Answer:
p = mv
Explanation:
The momentum of an object is given by the equation:
where
m is the mass of the object
v is the velocity
Since velocity is a vector, it follows that momentum is a vector as well, therefore it has a magnitude and a direction (the same as the velocity).
The SI unit of the momentum is
An important law related to the momentum is the law of conservation of momentum, which states that for an isolated system (= zero net external force on it), the total momentum of the system is conserved.
Answer:
The final energy of the system is 168 J
Explanation:
Heat energy released to the surroundings,
Work done, W = 222 J
The initial internal energy,
The change in internal energy is given by the formula,
The final energy of the system is 168 J
