What does an increase of temperature change do to the density of an object?

it makes the molecule vibrate and if there is not a strong bond, the molecules will break.

Most things expand when heated, but the mass stays the same. Greater volume, same mass= lesser density. That is why hot air baloons go up- hot air is less dense than cold air.

What will change the density of an object?
Either a decrease or increase in temperature will change the density of an object.
How do you change the density of any object?
Change the temperature.
What causes the buoyancy to increase or decrease?
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
Why does changing shape of an object dose not change the density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.
What are two ways to increase the density of an object?
Density = Mass / Volume To increase density, you could increase mass or reduce volume. To increase mass, you could use a different material (metal instead of plastic) to make the object. To decrease the volume, you could change its shape (square to round) or compress it (force all the air out if there is).
What will change the density of an object?
Either a decrease or increase in temperature will change the density of an object.
How can you change the overall density of an object?
In a simple way, since density = mass /volume, the density of an object can be changed by changing either mass or volume of an object .
How do you change the density of any object?
Change the temperature.
Does the shape of an object change its density?
Changing the shape CAN change the density. If you change it into a smaller shape, then you increase the density. However the mass will not change.

How does the temperature of an object change when its molecules collide?
increase
How can you increase density if mass is constant?
You can increase the density of an object with constant mass by decreasing the object's volume.
What are two ways to increase the density of an object?
Density = Mass / Volume To increase density, you could increase mass or reduce volume. To increase mass, you could use a different material (metal instead of plastic) to make the object. To decrease the volume, you could change its shape (square to round) or compress it (force all the air out if there is).
If the mass of an object cant be changed how do you increase the displacement of water?
change the density by altering the shape.
What happens to an object temperature when it gets more thermal energy?
Either the object's temperature will increase - or, the object will undergo a phase change (for example, from solid to liquid), in which case the temperature will stay the same.
Does a change in the mass affect the density of the object?
Adding mass may increase or decrease the density if the substance added is different. Merely changing the mass will not affect the density.
