Answer:
 joules
 joules
 joules
 joules
Explanation:
Let us convert the time in hours into seconds 

Change in internal energy 

where E is the internal energy in Joules
p is the power in watts 
and t is the time in seconds 

 Joules
 Joules
Amount of work done by the system

where P is the pressure and V is the volume
Substituting the given values in above equation, we get - 

 liter-atmospheres
 liter-atmospheres 
Work done in Joules 

 Joules
Joules

Substituting the given values we get - 

Thus

The capacitive reactance is reduced by a factor of 2.
<h3>Calculation:</h3>
We know the capacitive reactance is given as,

where,
 = capacitive reactance
 = capacitive reactance
f = frequency
C = capacitance
It is given that frequency is doubled, i.e.,
f' = 2f
To find,
 =?
 =?

       
       

Therefore, the capacitive reactance is reduced by a factor of 2.
I understand the question you are looking for is this:
A capacitor is connected across an AC source. Suppose the frequency of the source is doubled. What happens to the capacitive reactant of the inductor?
- The capacitive reactance is doubled.
- The capacitive reactance is traduced by a factor of 4.
- The capacitive reactance remains constant.
- The capacitive reactance is quadrupled.
- The capacitive reactance is reduced by a factor of 2.

Answer:
Heat has accelerated water atoms enough to break the surface tension which leads the liquid to turn into a gas 
Explanation:
The state of a substance depends on the distribution of its atoms, therefore any atmosphere change (in this case heat) enough to change the atoms Distribution results in a change of state.

Answer:
A. fuel mileage and longevity           
Explanation:
            For a person purchasing a car, car longevity is one of the main concern. They are also interested in many things such as maximum mileage and service life. 
            By properly monitoring and assessing few measures one can maintain the efficiency and longevity of the car. One such thing is by monitoring the liquid levels of the car. Certain liquids like the coolant or radiator water level should be well maintain in proper level in order to run the car economically.
Thus by doing this, one can optimize the car's longevity and the fuel mileage.
Hence the correct option is (A).
