Unless it were to suddenly go up in flames..... Definitely a physical. Just take a breath and think about it! These are easy points!

Physical sciences are an umbrella field of disciplines. The physical sciences include chemistry and physics for example. Therefore, physics is an example of one of the physical sciences.
Chemistry is the center and serves as the interface for many other sciences. Chemistry is such a broad subject. Please view the related source link at the bottom of the answer box.It is the study of matter and energy at the subatomic, atomic, and molecular levels.Chemistry is the study of the composition, structure, properties, and chemical reactions of matter.
a unified field theory is a type of field theory that allows all that is usually thought of as fundamental forces and elementary particles to be written in terms of a pair of physical and virtual fields.
Lewis, particularly referring to Gilbert N. Lewis, significantly impacted the field of science through his contributions to physical chemistry and chemical bonding. He introduced the concept of the covalent bond and the Lewis dot structures, which illustrate how atoms share electrons to form molecules. His work helped lay the foundation for modern theories of chemical bonding and molecular structure, influencing both theoretical and practical applications in chemistry. Additionally, his insights into acid-base theory and thermodynamics have had lasting effects on various scientific disciplines.
physical change
Magnets are a result of physical changes, as they are created by aligning the magnetic domains of certain materials (such as iron) through processes like magnetization. This alignment creates a magnetic field without altering the chemical composition of the material.
Yes, magnetizing iron is a physical change because it does not alter the chemical composition of the iron. When iron is magnetized, its magnetic domains align to create a magnetic field, but the iron itself remains unchanged chemically.
The force exerted by bullocks ploughing in a field depends on factors such as the weight of the bullocks, the friction between the plough and the soil, and the depth of the ploughing. Generally, it is a combination of the force required to pull the plough through the soil and the force needed to overcome the resistance of the soil.
To make an iron bar into a magnet you need to get a bar magnet and stroke the iron one way when you get to the end of iron take the magnet off and jump it back to the start and stroke repeat this several times and your bar will soon become magnetic. This is only temporary, therefore the iron will become normal after the magnetic field rubs off. This means that making iron into a magnet is indeed a physical change.
they are different because a chemical change is a change in which you apply heat to a object to change it in form physical change is when you change a form it size or shape but do not apply heat.So you will know the differnce because when you add heat to any object its a chemical change but expccpt boiling water
Magnetism is a physical property that is mediated by magnetic fields.The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.
It is a physical property >.<
No, magnetization is not a chemical reaction. Magnetic iron and non-magnetic iron are chemically the same substance. Magnetization is a process of alignment of atomic magnetic fields, which is a purely physical change, not a chemical change.
Ploughing, or plowing, is a verb that refers to tilling up dirt in straight rows in order to plant seeds or sprouts. An example of this word in a sentence would be, "The farmer began plowing up the field right before Spring came, that way he would be able to harvest the corn by September."
Planking is usually done after ploughing a field. It help to prepare a levelled seedbed suitable for a normal crop stand.
NO!They are attracted to the North and South Poles.
