What has more energy something hot or something cold?
Hot things have more energy than cold one.
Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
Which form of energy moves spontaneously from hot objects to cold objects?
Thermal energy moves spontaneously from hot to cold objects.
When does an object have more thermal energy when it is hot or cold?
Hot.
What is the difference between cold and hot lasers?
Cold lasers are safer and deal less pain than hot lasers. Cold lasers are usually used for repairing skin damage and treating pain and inflammation. Hot lasers are simply used for burning things.
What has more energy something hot or something cold?
Hot things have more energy than cold one.
Wikipedia is ice hot or cold?
Ice is neither hot or cold. Technically, nothing is cold. Everythin is based on energy. The more energy something has, the more "heat" it puts off. Ice feels cold against our skin because it has less energy than we do.
Why water evaporates quicker on a hot day than a cold day?
Hot water need less energy to be evaporated than cold water.
What experiment could see if hot water evaporates faster than cold water?
Hot water need less energy to be evaporated than cold water.
What tells you that cold things cold and hot things hot?
A thermometer
How does a tema keep hot things hot and cold things cold?
Turtle
Do both hot and cold have energy?
Yes (with the exception of absolute zero) but the energy in hot and cold is always heat energy. (Cold is defined as the absence of heat)
Which has a higher entropy a hot water or a cold water?
Entropy is the measure of disorderness. Hot water --> more energy --> less stable --> more disorderness (than Cold water). Therefore, Entropy of Hot water is greater than that of Cold water.
What happens to thermal energy when you mix hot and cool water together?
Since hot water is less dense that cold air the hot water will rise and the cold would sink then it keeps doing this in a circular motion 'till the thermal energy reaches to thermal equilibrium.
How does temperature increase or decrease?
Temperature is the average Kinetic energy of molecules in an object. A hot object has more kinetic energy and a cold object has less kinetic energy.
Which form of energy moves spontaneously from hot objects to cold objects?
Thermal energy moves spontaneously from hot to cold objects.
Why is it better too wash things in hot or warm water rather then cold?
Hot or warm water will frequently do a better job is dissolving dirt- but it is not always "better". Some things are damaged by hot water, and should be washed in cold water. Colors tend to fade less in cold water.
