A piston cylinder system usually makes use of a gas as the substance that is expanded and contracted. Internal combustion engines are used in cars to convert fuel into mechanical energy. The continuous up and down motion of the piston causes the crankshaft to rotate, which also does work to power the car.

Joe is concerned about the carbon dioxide emissions from his daily commute and the impact that it is having on global warming In
Vesna [10]

Amount of CO₂ emission per day is 11,356.23 g.

<u>Explanation:</u>

Joe travelling distance per day = 60 miles

Carbon dioxide emission per day = 20 mpg

Now we have to find the amount of carbon dioxide emitted per day by dividing the distance by the emission per day given in gallons.

Amount of Carbon dioxide emission = $\frac{distance}{emission amount}

Amount of CO₂ emission in gallons  = $\frac{ 60 miles}{20 mpg}  

                                                            = 3 gallons

Now we have to convert the gallons to grams as,

1 gallon = 3,785.41 g

3 gallons = 3 × 3785.41 g = 11,356.23 g

So the emission of CO₂ per day is 11,356.23 g.

Why are ionic solids poor conductors of electricity
marshall27 [118]

Answer:

Ionic compounds don't conduct electricity very well because the charge carriers can't move through the crystal. They can conduct heat because the kinetic energy itself is the "heat carrier”.

Hope this helps :)
