What else can I help you with?
Is a magnetic force a noncontact force?
Yes, a magnetic force is a noncontact force because it can act on an object without physically touching it. Magnetic fields can exert forces on objects that have magnetic properties.
How do chemical and physical properties differ?
chemical properties cannot be determined just by viewing or touching the substance and physical properties can be observed or measured without changing the composition of matter.
What is a metal that can attract other materials without touching them?
Iron is a metal that can attract other materials without touching them due to its magnetic properties.
What are the properties of volume density and magnetism?
Volume density refers to the amount of mass present in a given volume of a substance, while magnetism is a property that allows an object to exert a force on other objects without physically touching them. Materials with higher volume density have more mass packed into a specific volume, while magnetic materials have domains of aligned magnetic moments that produce a magnetic field.
What is called the direct transfer of heat from one substance to another substance that it is touching is called?
the direct transfer of heat from one substance to another substance that it is touching is called
Magnetic forces can repel without touching True or false?
True. Magnetic forces can repel objects without them physically touching because the magnetic fields generated by the objects interact to create a repelling force.
A magnetic interaction only occurs if the interacting objects are touching?
False. Magnetic interactions can occur even when the interacting objects are not touching. Magnetic fields can exert forces on objects at a distance, such as between a magnet and a piece of metal.
Why is the direct transfer if heat from one substance to another substance that is touching?
The direct transfer of heat between two substances that are touching is conduction.
What is direct transfer of heat from one substance to another substance that is touching called?
conduction
What is the direct transfer of heat from one substance to another substance that is touching called?
Conduction.
Can magnets attract objects without touching them?
A magnet has a magnetic field around it. The magnetic field causes a magnetic force that can attract objects to the magnet.
What does a chemical property give a substance the ability to do?
A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
