Answer:
Both are incorrect.
Explanation:
PCV valve opening is dependent on amount of manifold vacuum value. The opening cannot decrease due to part throttle operation. The PCV system is a tampered valve whose opening depend upon intake manifold vacuum. PCV valve is supported by a spring and is initially in a closed position.

I believe this is what ur looking for
C. seems like the best answer. i may be wrong so don’t quote me on that
Answer:
Check the explanation
Explanation:
The transferred energy calculations can be done using the equation:
This is when:
• power is calculated in watts (W)
• energy is calculated in joules (J)
• time is calculated in seconds (s)
it can also be calculated by utilizing the same equation but with different units:
• when energy is measured in kilowatt-hours (kWh)
• when power is measured in kilowatts (kW)
• and when time is measured in hours (h)
kindly check the comprehensive step by step calculation to the question in the attached images below
Answer:
b). False
Explanation:
Thermodynamic property are of two types
1. Intensive property
2.Extensive property
Intensive properties are those properties that do not depend on mass. For example, Specific volume, temperature, specific heat capacity,density etc
Extensive properties are those properties which depends on mass.
For example, volume, heat capacity, etc.
Now when a specific property (intensive property) is multiplied with mass of the system, we get extensive property .
We know that density is an extensive property having unit of kg per meter cube.
Now the reciprocal of density is specific volume which is also an extensive property having unit of meter cube per kg.
Now if we multiply the specific volume with the mass we get volume which is an extensive property and not an intensive property.
Thus, we get extensive property when we multiply mass to any specific or intensive property.
