What are the physical changes that occur during the recycling of aluminium cans?
magnets are used to pull out any accidental iron or steel cans in the mixthe cans are crushed together to form an aluminum baleseveral bales are placed in a crucible and meltedmelted aluminum is poured into a mold and solidified into an ingotthe ingot is rolled or extruded to form the desired shapeif cans are desired rolled sheet aluminum is stamped to form the bases and lids
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
How do the particles that make up matter compare during physical and chemical changes?
During physical changes, the particles that make up matter remain the same and only their arrangement or state changes. In contrast, during chemical changes, the particles undergo a rearrangement or bonding at the atomic level, resulting in the formation of new substances with different properties.
What are changes happen to the food?
Food undergoes physical, chemical, and biological changes during storage and preparation. Physical changes may include freezing, heating, or grinding. Chemical changes involve oxidation, browning, or fermentation. Biological changes occur when microbes grow and spoil the food.
Is baking a cake physical or chemical changes?
Baking a cake involves both physical and chemical changes. The physical changes include mixing the ingredients, changing the shape and texture of the batter, and the evaporation of water during baking. The chemical changes occur when the heat causes the baking powder to react, creating bubbles that make the cake rise, and when proteins and starches denature and coagulate during baking.
What are the physical changes that take place during the recycling of aluminium cans?
During the recycling of aluminum cans, the cans are collected, shredded, melted, and purified. The molten aluminum is then cooled and solidified into ingots or sheets that can be used to manufacture new aluminum products. This process saves energy and reduces the need for mining new aluminum ore.
How can you tell if a physical reaction is occuring?
During a physical change the chemical molecule is not affected; physical changes are changes of phase or form.

At what age does the penis typically undergo physical changes during puberty?
The penis typically undergoes physical changes during puberty around the ages of 12 to 16.
Which property of matter changes during a chemical change but does not changes during a physical change?
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
What are some physical changes during puberty?
Boy: deeper
Can new compounds form during a physical change?
no because in a physical change it does not change the chemical make up, however, it does during a chemical change
Can a substance produced during a physical change easily change back?
Yes. Chemical changes are irreversible, but physical changes can easily be changed back
What physical changes happens during evaporation?
The transformation of a liquid to a gas.
What property stays the same during physical or chemical changes?
The mass.
Are state changes physical or chemical changes?
State changes are physical changes because they involve a change in the physical properties of a substance, such as its form or state of matter (solid, liquid, gas). No new substances are formed during a state change, making it a physical change rather than a chemical change.
Will a north pole magnet attract to a piece of aluminium foil?
Neither. Aluminum Foil has no magnetic properties.
