How is it possible for a heat pump to remove thermal energy from cold objects and add it to a hotter object?
Basic trick is to make a transfer fluid that is (much) hotter than the "hotter object" at one point in the cycle. Heat still flows from hot to cold ... but note that the system is not overly efficient.
A measure of how hot or cold somthing is?
temperature!A good thermometer, a thermocouple, a thermoresistance, a pyrometer, etc.
What happens when something gets cold?
When something gets cold, its molecules slow down and move closer together, causing the material to contract and become more dense. The decrease in temperature can also affect the electrical conductivity and chemical reactions of the material.
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.
What determines whether something will feel cold or hot?
The sensation of hot or cold is determined by the temperature difference between the object and our skin. When an object is colder than our skin temperature, it feels cold as it absorbs heat from our skin. When an object is hotter than our skin temperature, it feels hot as it transfers heat to our skin. Temperature perception can also be influenced by factors like humidity and individual sensitivity.
Does hot water melt cold things faster than cold water?
Of course. When something is hotter than something else, it means it has more energy, which also means it's particles are moving more. The particles of the water will bump into whatever your trying to melt and give it some of the particle's energy, which hopefully will be enough make it become a liquid as well. The hotter the water the more energy it has, and the more quickly it can melt "things".
How could something that is cold become warm?
By the application of energy.
What would cause downstairs radiators to be cold while upstairs are hot?
It's because heat travels upwards and cold downwards so naturally the upstairs will become hotter then the downstairs.
The process by which snow or ice change to water?
the process is called melting, and the hotter something cold like ice is the quicker it will milt. Hope this has helped
What is hot water?
hotter than cold water
How warm or cold is neptune?
hotter than hot
How cold is south pole's summer?
Just a bit hotter than your cold coffee
Why does density change when something gets warm or hotter?
density changes when something is heated or cooled because the tiny particles inside the object are either separating(with heat) or getting closer together(cold)
How hot should gravy be when served?
It should be warm or if people like it hotter then hotter but never cold yuk..
What happens to air when it gets hotter and denser?
When air gets hotter, its particles move faster and spread out, causing the air to expand and become less dense. Conversely, when air cools down, its particles slow down and move closer together, causing the air to contract and become denser.
When it is hot and it rains is it the same temp as when it is cold and it rains?
No it is hotter
Why will the sun get hotter and hotter?
It wont, as the sun expands over time, the sun will become cooler and cooler.
