When you heat an object up what happens to the atomsmolecules that it is made of?
when you heat an object up what happene to the atomsmolecules that it is made of?
When you add an object in water why does it take longer to heat up?
because the object needs also to heat up
How high above a burner should you place an object you want to heat?
Unless you want to limit the heat, it should be placed within a few centimeters of the flame, because the heat dissipates pretty quickly if the heated object is any higher.
Heat will flow from a hot object to a cold object until the objects reach what?
In a closed system, yes. Both objects will be at the same thermal energy level, and neither will be able to release any to the other. In the real world, this is not the case, heat would continue to dissipate until the object reaches the same thermal energy level as the air around it, approximately.
When heat is absorbed by an object the speed of the particles in the object is?
increased.

When you heat up an object the particles in the object move?
faster
An object can heat up if?
it has less heat than the surroundings
What energy is it when you rub an object on any object?
Heat - generated by friction.
Is density is a measure of how much heat there is in a volume of a substance?
"Any object, wholly or partially immersed in a stationary fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." (Archimedes) And this is independent on the heat.
Which absorbs heat which gives of heat?
Any object which is cooler than its surroundings absorbs heat and any that is warmer, gives off heat.
Why doesn't a plastic spoon get hot in a cup of tea?
It does. Any object will heat up (or cool down) to the ambient temperature.
Is the direct transfer of heat through a substance?
heat travels to any colder object
What will a cool object do when a warm object is brought near it?
The cool object will absorb heat from the warmer object, and warm up.
How is heat energy lost from an object?
There are three ways to transfer heat energy (conduction, convection, radiation); any of the three can occur, for an object to lose heat energy.
What happens when a drill is used to bore in an object?
Friction cause the object to heat up.
