How much heat is needed to condense 22.25 grams of nitrogen gas at –195.8°C? The latent heat of vaporization of nitrogen is 199.
2 answers:
The correct answer to the question is : 4427.75 J.
EXPLANATION :
As per the question, the mass of the nitrogen gas m = 22.25 gram.
The latent heat of vaporization of nitrogen
As per the question, the nitrogen gas will condense. During condensation, the nitrogen gas will lose or release heat equal to its latent heat.
Hence, the heat released by nitrogen gas Q =
= 22.25 × 199.0 J
= 4427.75 J.
Hence, the amount of heat released will be 4427.75 J.

Explanation:
The principle of conservation of momentum, states that if the sum of the forces acting on a system is null, the initial total momentum of the system before a collision equals the final total momentum of the system after the collision. The collision is completely inelastic, which means that the players remain stick to each other after the collision:
