Why do your feet feel colder when you get into a pool using second law of thermodynamics?
The basic principle here is that heat tends to flow from hotter objects to colder objects - in this case, from your feet to the cold water.
First and second laws of thermodynamics?
First Law of Thermodynamics: Energy can be converted from one form to another, but cannot be created or destroyed.Second Law of Thermodynamics: The second law of thermodynamics states that for any process occurring in a closed system, the entropy increases for an irreversible system and remains constant for a reversible system, but never decreases.
Why does cold water heat up when hot water is added?
When hot water is added to cold water, heat energy is transferred from the hot water to the cold water through a process called conduction. This causes the temperature of the cold water to increase as it absorbs the heat energy from the hot water. The two temperatures eventually reach an equilibrium where they are at the same temperature.
Why does a cold shower cool you down?
Thermodynamics.
What temperature will a 150ml of water freeze?
That depends. Ask not: 'How long does it take 150ml of water to freeze?' Rather ask: 'How cold is the temperature surrounding the water?' and: 'What is the heat conductivity of the vessel containing the water?' According to the second law of thermodynamics, an object hotter than its surroundings will tend to cool and vice versa. So, the cooler the surrounding temperature, the faster the water will freeze.
How would you describe the water of rivers stream and lakes?
cold and worst than the beach
What law of thermodynamics state the fact that heat flows from hot to cold?
geometric shape
Describe what would happen to a cold empty glass if it was suddenly placed in a hot humid room?
Water vapors are condensed on the cold surface.
Describe the method of heat transfer involved when you mix hot water with cold water to make lukewarm water?
conduction and convection
Does hot cold or salt water freeze faster?
Cold water, being the closest to freezing point, will obviously freeze the fastest. Hot water will freeze the second fastest, and salt water barely ever freezes, except in very cold conditions.
Why the room cannot be cooled by opening the doors of refregerator?
Because of the second law of thermodynamics. A fridge is essentially moving hot air from the inside of the fridge to the outside environment. By opening the door you are connecting the hot and cold reservoir.
According to the second law of thermodynamics which is a requirement for thermal energy to flow from colder objects to hotter objects?
The second law of thermodynamics states "energy systems have a tendency to increase their entropy rather than decrease it." This can also be stated as "heat can spontaneously flow from a higher-temperature region to a lower-temperature region, but not the other way around." Heat can appear to flow from cold to hot, for example, when a warm object is cooled in a refrigerator, but the transfer of energy is still from hot to cold. The heat from the object warms the surrounding air, which in turn heats and expands the refrigerant. The refrigerant is then compressed, expending electrical energy. so the second law of thermodynamics is your answer I believe.... there are 3 proper laws of thermodynamics with a possible fourth, fifth and sixth still being postulated.
