<h3><em>Answer:   Physical properties of a substance are characteristics that can be observed without altering the identity of the substance. Color, odor, density, melting temperature, boiling temperature, and solubility are examples of physical properties. Physical properties can be used to identify a pure substance.</em></h3><h3><em>A pure substance has a definite and constant composition — like salt or sugar. A pure substance can be either an element or a compound, but the composition of a pure substance doesn't vary.</em></h3>

The non-contact forces portfolio please help I'm just confused about what I'm supposed to do.
MatroZZZ [7]

The non-contact forces portfolio includes Gravitational force, Magnetic force and Electrostatic force.

<h3>What is non contact force?</h3>

Non contact forces are those forces which are applied on any object without any physical interference or contact.

Some non-contact forces are:

  • Gravitational force: It acts between two objects and depends on the masses of the object and distance between that objects.
  • Magnetic force: It acts due to the motion of the charged particles.
  • Electrostatic force: It is a type of induced force which is generated due to rubbing of two objects but when it is generated it remains even after removing the contact of previous objects.

Hence Gravitational force, Magnetic force and Electrostatic force are the non-contact forces.
