Does gravity increase or decrease when heat increases?
No. You don't weigh more or less on a hot or cold day.
Is conduction of heat is a physical property?
Temperature is a physical property and it determines how hot or cold an object is. Heat flow is always from hot to cold.
Heat flows from cold to hot?
It's simple thermodynamics. In the case of conduction (where two objects are touching each other), the molecules of the hot object contact the molecules of the cold object, and energy is transferred from the hot molecule to the colder one (remember, the hot object is hot because its molecules have more energy). This process continues until all of the molecules have the same energy (are the same temperature).
Does Astronomers believe that the universe began as an enclosed cold object?
No. The origin of the Universe is believed to have been very HOT, not cold.
Is statch more soluble in hot or cold water?
hot water
What is more dense a cold object or a hot object?
A cold object is more dense.
When does an object have more thermal energy when it is hot or cold?
Hot.
Does a hot or cold object give off more radiation?
hot
Does heat travel from a hot object or cold object?
heat travel from a hot object first then to cold object!
What term describes how hot or cold an object is?
What term describes how hot or cold an object is?
What makes an object hot or cold?
We perceive an object as hot or cold according to how fast its particles are moving. The faster they move, the hotter the object.
In order for heat to be transferred by conduction which of the following must occur A cold object must be heated with hot air. A hot object must be directly touching a cold object. The Sun must heat t?
A hot object must be directly touching a cold object.
What is transferred from a hot object to a cold object?
Thermal energy.
Does gravity increase or decrease when heat increases?
No. You don't weigh more or less on a hot or cold day.
How does hot and cold affect an objects size?
Heat(Hot) makes a object expand or get bigger. Cold makes a object shrink or get smaller.
Why does hot coffee weigh more than cold coffee?
sugar dissolves faster in hot coffee because the temperature makes it melt quicker than the process of cold coffee.
How do you know that an object is hot or cold?
Touch it
