What happens to the particles of an object as it heats up?
nothing
What happens to an object when it absorbs light energy?
heats up
What happens to speed of the particles if the size of the object gets bigger?
it blows up and down, up and down
Does the particles in water move faster when it heats up?
no it slows down!
What happens to a material when it absorbs light?
Normally, it heats up.
What happens to the particles of an object as it heats up?
nothing
What happens to an object when it absorbs light energy?
heats up
What happens to an object's density when it heats up and expands?
The density decreases.
Explain what happens when radiation heats up an object?
First radiation is the transmission of high energy particles. when you apply radiation to an object the energy from those particles is transmitted into the object. this additional energy is transmitted into the particle by "bumping" into the atoms or molecules that make up this object. by hitting those atoms with these fast moving particles you transmit that energy into the atoms of the object. this causes the atoms to move much faster than they were before. and the movement of these atoms contributes to the temperature of the object
What happens to the volume of a substance when it heats up?
it gains energy and particles start to move along in all directions.
What increases the temperature of a substance?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
What happens to speed of the particles if the size of the object gets bigger?
it blows up and down, up and down
How do ratdiation heat things?
heat radiation gives an object energy and it begins to vibrate (molecular level) which heats the object. Its like a person jumping around will heat up, works the same with particles in an object
When the temperature of a substance decreases increases what happens?
The temperature of a substance increases as the mean random kinetic energy of its particles increases. This is because temperature of an object is directly proportional to the kinetic energy of its particles. Thus when the particles move faster as a whole, such as when the object is put near a flame, the object heats up.
Does the particles in water move faster when it heats up?
no it slows down!
What do you think happens when some air heats up and other air is cool?

What does friction do to an object that is moving?
Slows it down, and heats it up.
