Explanation:
<u>Step 1: Define</u>
<em>Identify</em>
[Function] f(x) = 6x + 1.5
[Given] f(2.5) is <em>x</em> = 2.5 for function f(x)
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em> [Function f(x)]: f(2.5) = 6(2.5) + 1.5
- Multiply: f(2.5) = 15 + 1.5
- Add: f(2.5) = 16.5
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.
