Frost forming on a car window is a physical change because it is a reversible process where water vapor in the air solidifies into ice crystals when it comes into contact with the cold surface of the window. The chemical composition of the water molecules remains the same before and after the frost forms.

Why is a crashing car a physical change?
A crashing car is a physical change because the collision alters the car's shape and form, but the chemical composition of the materials remains the same. No new substances are produced as a result of the crash, so it is considered a physical change.
When rust forms on a car is that a physical change?
The formation of rust on a car is a chemical change, not a physical change. It occurs when the metal reacts with oxygen and moisture in the air to form iron oxide. This process alters the chemical composition of the metal, making it different from its original state.
What physical quantities discussed in this chapter change most when a junked car is neatly crushed into a compact cube?
Some of the physical quantities that change the most when a junked car is crushed into a compact cube include volume, density, and structural stability. The volume of the car decreases significantly as it is crushed, leading to a much higher density in the compact cube. The structural integrity of the car is also altered, with the transformation from a complex shape to a simple cube impacting its stability and strength.
When a car stop why are you tending to move forward?
When a car stops suddenly, inertia causes the passengers to continue moving forward due to their own momentum. This happens because the car decelerates faster than the passengers inside, causing them to lean or move forward until they are brought to a stop by the seatbelts or objects in the car.
If a car was crushed into a cube which would change mass or volume and why?
The mass of the car would remain the same because mass is a measure of the amount of matter in an object, which does not change during a physical transformation. However, the volume of the car would decrease significantly as it is compressed into a cube shape.
Wet in Lincoln LS?
Frost inside the car? With no car window left open.
Why are there lines at the back of the car?
If you are talking about the lines in the back window of a car, those are the heating elements for cleaning fog, frost and ice from the window. If that isn't what you meant, please clarify the quesiton.
What does you envy the de frost in the rear window of your car mean?
Do you mean defrost, as in a car window. Maybe some reference to defrosting the rear window with a button inside the car and not having to get out in the cold a scrape, scrape, scrape so you can see behind you while driving.
How do you fix a car window that has an air leak?
change the window seal / gasket.
Is a car crashing a physical or chemical change?
The key here is what happens to the matter. Does it change into a different material or just change shape? If the metal changes into a new substance like iron into rust then it would be chemical but this is definitely a physical change. - - - - - Car crashes can cause both physical and chemical changes. The bending of the car is a physical change, but if the wreck catches fire that's a chemical change.
Is washing a car a physical change?

What causes a car window to implode?
A car window might implode when it is exposed to a large change in pressure. For example, a pressure change during a tornado or while sinking into deep water could cause the window to implode.
Why is smashing a car a physical change?
Smashing a car is a physical change because it alters the physical form or shape of the car but does not change its chemical composition. The car can still be repaired or restored to its original state by reshaping the damaged parts.
