|
how does a magnetic field form when current travels through a wire
|
goes in a circle around a wire
|
|
|
state relationship btw magnetic field and current that travels through a wire
|
directly related
|
|
|
explain what magnetic domains are
|
smallest piece a magnet can be broken into , still has a "N" and "S" pole
|
|
|
how are domains positioned if there is a magnetic field present and if the magnetic field is not present
|
the domains in the temp may align with the present magnetic field
|
|
|
if a magnet is cut into its smallest piece, how many magnetic poles are present
|
2 (N&S)
NO MONOPOLES EVER! |
|
|
when an iron rod is inserted into a solenoid , what is produced?
|
an electromagnet
|
|
|
what is the direction of force on a current carrying wire in an external magnetic field
|
perpindicular
|
|
|
a current-carrying conductor in and perpindicular to a magnetic field experiences a force that is what?
|
coming out
|
|
|
what happens to the internal energy of an ideal gas when it is heated from 8 degrees celcius to 3 degrees celcius
|
decreases also
|
|
|
how does heat flow between two bodies in thermal contact?
|
high temp to low temp
|
|
|
a substance registers a temp change from 60 degrees celsius to 100 degrees celsius. this corresponds to an incremental change of what?
|
internal thermal energy
|
|
|
if a temp is 296k what is the temp in celsius
|
Tc=T-273.15
Tc=296-273.15 Tc=22.85 degrees celsius |
|
|
how does energy transfer as heat moves?
|
high temp to low temp
|
|
|
how does energy move btw particles if there is a temp difference btw two substances?
|
high temp to low temp
|
|
|
explain the relationship btw temp and ke
|
directly related------temp is a measure of how much KE and object has
|
|
|
explain the difference btw conduction, convection and radiation
|
conduction: heat transfer through solid objs touching
convection: fluids are warmed and cause currents (warm fluids are less dense than cool and become more dense) radiation: emits waves and gives off heat |
