When an object is heated why it is demagnetized?
Heat increases the momentum of electrons and randomizes their spin orientation. Randomized orientation of spin reduces the magnetism.
What is the movement of heat called?
Convection is heat transfer by the movement of heated fluids. Heat transfer is the movement of energy from a warmer object to a cooler object.
How the thermal energy of an object changes when the objects temperature changes?
when abody is heated definitely its thermal energy increases so far that it can even cause a change in its physical appearance
Why do materials expand once heated?
This is called thermal expansion. When an object is heated, it's particles move faster. This causes greater separation between the particles and the object expands. The coefficient of thermal expansion describes how much an object will expand per degree with the same applied pressure.
What happens to particles as the temperature increases?
As the temperature of a substance increases, its molecules move faster and therefore take up more space. This generally causes a substance to increase in volume when heated.
Does the volume of an object change if heated?
The volume of a substance increases when heated
What happens to the light emitted by a heated object as its temperature increases?
Initially invisible infra red radiations. Then as temperature increases it becomes red. As still temperature increases it turns into yellow. When further increase happens, it starts giving out almost all colors including blue, violet and so it seems white hot. As an object is heated, it's maximum electromagnetic frequency increases. So you can measure the heat of an object by its emitted spectrum.
When you heat up an object does the average kinetic energy of its particles decrease?
No: Upon being heated, the average kinetic energy of the particles that compose the object increases.
What is an object that increases in velocity called?
Accelerated body
What is the movement of heated fluids called?
Convection is heat transfer by the movement of heated fluids. Heat transfer is the movement of energy from a warmer object to a cooler object.
When an object is heated why it is demagnetized?
Heat increases the momentum of electrons and randomizes their spin orientation. Randomized orientation of spin reduces the magnetism.
When a liquid is heated how does its volume change?
When a gas is heated, its' volume increases.
What happens to a particle in a liquid when heated?
The Particles Vibrate , Causing the liquid to evaporate leaving behind a gas. ! Sophie :)
What happens to the force of an object if the object increases?
The acceleration increases.
What increases as the speed of an object increases?
the kinetic energy of the object
If velocity increases this is called?
If speed increases, or if the moving object curves up or down or to the right or to the left, or if speed decreases, any of these events is called "acceleration".
Energy of an object increases when what is done on the object?
When force is done on the object
