Write one example of a physical change and one example chemical change
mojhsa [17]
Physical change = changes the physical properties (more commonly known as it's look)
Chemical change = changes the chemical properties into an entire new chemical form
Examples of physical change would be melting ice cubes or sugar cubes.
Examples of chemical change would be cooking eggs or burning paper because you're changing its chemical properties.

netineya [11]
This statement is false.
The correct statement would be,
"W<span>hen you approach an intersection and see a truck ahead signaling a right turn, you should stay behind the truck, away from the curbside, until the turn is completed."

Larger vehicles require a larger space to turn, being next to the truck and close to the curbside will only make it more difficult for the truck driver to complete the turn. This in turn will waste more time or even block traffic while the truck driver tries to complete the turn in the difficult situation that could have easily been avoided.</span>
