Answer: The correct answer is option d.
Explanation: Energy stored into gasoline is converted into another form of energy. This was very well explained on the basis of Law of conservation of energy. This law states that energy is conserved in the system which means that energy is converted from one form to another form.
The energy stored into gasoline is converted into mechanical energy which helps the car to move and some of the energy is lost in the form of heat.
Hence, the correct answer is Option d.
Answer:
The answer is
<h2>0.95 atm</h2>
Explanation:
To solve the question we use the following conversion
That's
1 mmHg 
0.0013 atm
So we have
If 1 mmHg 0.0013 atm
Then 732 mmHg will be
732 × 0.0013 atm
We have the final answer as
<h3>0.95 atm</h3>

Answer:
4.9 x 10²²hockey pucks
Explanation:
Given parameters:
Number of moles of hockey = 0.0814moles
Unknown:
Number of pucks there = ?
Solution:
A mole of a substance is made up of Avogadro's number of particles.
Therefore;
1 mole of hockey pucks will contain 6.02 x 10²³ hockey pucks
0.0814 mole of hockey pucks will contain :
0.0814 x 6.02 x 10²³ = 4.9 x 10²²hockey pucks
1 mole ------------- 22.4 L ( at STP)
?? moles --------- 5.58 L
5.58 x 1 / 22.4 => 0.249 moles of N₂
