What else can I help you with?
Why is it cold when there are less people and warm when there are more people?
our bodies always releases heat. so, when there are less people in a room, there bodies release less heat and we feel cold but when there are more people in a room there bodies release more heat and we feel warm.
Is it true that heat can pass from cold bodies to hot bodies?
No, heat naturally flows from hot bodies to cold bodies in a process called heat transfer. This is described by the second law of thermodynamics, which states that heat flows spontaneously from higher temperature regions to lower temperature regions.
Why does the ice cream feel cooler to the teeth than the ice cold water?
Ice cream feels cooler to our teeth than ice cold water because during the change of state some amount of heat is absorbed which is known as Latent Heat. So in ice no hidden heat is absorbed while in cool water latent heat of fusion or melting is absorbed.
What is a reaction in which heat is involved?
A reaction in which heat is produced is called exothermic. A reaction in which heat is absorbed (or one that produces cold) is called endothermic.
Is cold a matter?
Cold is not a matter, but rather a description of the absence of heat energy. Cold is perceived when objects or substances have a lower temperature than our bodies, causing heat to flow from our bodies to the colder object, making us feel cold.
Will cold blooded animals survive without heat energy?
No, cold blooded animals cannot survive without heat energy because their bodies need to heat up so they can do things like moving and eating. If an animal didn't heat their bodies up, they would die.
Why is air cold?
because of nature !
Is sweating is a prof of heat absorbed or heat release?
heat release
Can a cold spoon transfer heat?
No. Heat can only be transferred to a cold spoon, not the other way round (as there is no heat in a cold spoon to transfer). A simple example is when a cold teaspoon is used to stir a hot cup of tea. When the spoon is withdrawn, it is hot.
Does heat energy release during evaporation?
Absorbs heat. Think of a spray can: as you spray the can feels cold. this is because heat is absorbed by the liquid that is evaporating in the spray can to drive out what is being sprayed.
Does heat travel from cold objects to hot objects?
No, heat naturally flows from hot objects to cold objects. This is based on the second law of thermodynamics, which states that heat always moves in the direction that increases the entropy of a system.
What can light convert to when absorbed?
heat">heatlight can convert to HEAT when absorbed.
