What is more dense a cold object or a hot object?
A cold object is more dense.
When a hot object touches a cool object the particles in the hot object cause the particles in the cool object to?
It causes it to vibrate which causes it to heat up
When is one object hotter than another?
When one object is hotter than another, heat will be transferred from the hot object to the cold object. The hot object will cool down, and the cold object will heat up, until they are the same temperature.
Why do hot liquids rise in convection?
Hot liquid is less dense. After it has released heat at the top it is more dense. Its a continious cycle of rising and falling.
When does an object have more thermal energy when it is hot or cold?
Hot.
What is more dense a cold object or a hot object?
A cold object is more dense.
Is cool air dense?
No it is more dense than hot air
Is cool air less dense?
No it is more dense than hot air
Does dense air move from hot air to cool air?
No. Dense air is cool air.
When a hot object touches a cool object the particles in the hot object cause the particles in the cool object to?
It causes it to vibrate which causes it to heat up
Why does a hot air baloon rise?
They rise because the hot air from the fire in the balloon art weighs less then the cool air around the balloon. so it floats up and rises. It uses convection energy. Hot air is less dense and rises and cool air is more dense and sinks.
Match each body to its best description A. black hole an old very dense hot star that is cooling B. red giant a large star that is relatively cool C. white dwarf a an object so dense that even light c?
Black hole- an object so dense that even light cannot escape its gravity Red Giant - a large star that is relatively cool White Dwarf - an old, very dense hot star that is cooling Nebula - A mass if gas and dust
Is the air on a hot humid day less dense or more dense than on a hot dry day?
it is less dense
How does heating affect an object?
The hotter an object is, the more vigorously its atoms or molecules vibrate, and in doing so generally they take up more space (the object expands). This implies that a hot object is less dense than when it is cooler (because of its volume increase)
What is something cool?
An object that is not hot or warm, but not cold either.
Why does hot water ries?
In general, hot means the substance is less dense. Less dense things tend to rise when they are in more dense things.
What is more dense hot tea or iced tea?
hot tea
