When does freezing occur in the water cycle?
Water doesn't spontaneously freeze (thank goodness). It freezes because heat is being removed from it (by a fridge, for instance). As heat is gradually removed the molecules of water vibrate less and less as they lose energy. Eventually the random vibration almost stops and the molecules form into a fixed array like an army on parade. This lattice structure is so much stronger than individual water molecules flying about hither and thither and is called ice.
Why can't -5K exist?
0K is absolute zero, meaning that the system contains zero thermal energy. Temperatures below absolute zero are impossible.
What states that the two system which are in thermal equilibrium with a third system are in thermal equilibrium with each other?
Zeroth law of thermodynamics: If two systems are in thermal equilibrium with a third system, they must be in thermal equilibrium with each other. This law helps define the notion of temperature.
Ice at 0 degree celsius is more effective in cooling than water at 0 degree celsius?
In theory, the effectiveness of the cooling process depends on the ability/capacity of the cooling element (in this case, water and ice) to absorb energy from the system, until the system goes to equilibrium.Ice is more effective than water in cooling liquids because ice needs additional energy to convert itself to water at 0ºC. Thus, it absorbs more heat from the liquid system it is in, making the liquid system cooler. In other words, ice at 0ºC is simply a "level" higher than water at 0ºC. The additional energy requirement is called "enthalpy of fusion.Simple mathematical illustration:X = Y + cwhere:X = energy that ice at 0ºC can absorb until equilibriumY = energy that water at 0ºC can absorb until equilibriumc = constant (enthalpy of fusion)Step by step mechanism is:1. Ice at negative degrees Celsius absorbs energy to make the ice temperature 0ºC2. Ice at 0ºC abosrbs energy to convert the ice to water (still at 0ºC)3. Water at 0ºC absorbs energy until the system reaches equilibriumIce at 0ºC starts on step 2 while water at 0ºC starts on step 3.. Hope it can be of help..
Is the average kinetic energy of particle in a block of ice at 0 degrees the same as or different from the average kinetic energy of the particle in a gas-filles container at 0 degrees Celsius?
the same
How much energy is needed to freeze 1 Gramme of water at 10 Celsius to 0 Kelvin or Absolute Zero?
First of all, energy needs to be removed from the system to cool it towards Absolute Zero. Second, reaching Absolute Zero is not possible.
How much energy must be removed from a 200 G block of ice to cool it from 0 degrees to -30 degrees?
12kJ
The temperature at which no more energy can be removed from a substance?
The temperature at which no more energy can be removed from a substance is absolute zero, which is 0 Kelvins or -273.15 degrees Celsius.
What is the temperature called at no more energy can be removed from matter?
-273.15 degrees Celsius (-459.67 degrees Fahrenheit) is the temperature at which no more energy can be removed from matter.It is called Absolute Zero and marks the 0 for the Kelvin and Rankine scale.

How much energy is generated from freezing 2.5g water?
0
What is the temperature at which no more energy can be removed from matter?
Absolute zero. On the Kelvin scale of heat measurement, 0K is the point at which no more energy can be removed or −273.15°C / −459.67°F. There is not enough energy there at 0K to transfer any movement from the substance to another substance.
How does kenetic energy stop and go by friction?
Let's get started! An object in motion possesses kinetic energy and to bring the object to a stop this kinetic energy must be removed. ... A mechanical brake applies a friction force to convert the kinetic energy of the vehicle into thermal energy which then dissipates into the atmosphere.
How much heat must be removed from 7.50 kg of water to freeze it at its melting point?
2500
How much energy does it take to cook a hot dog?
0 J, Eat it raw :)
How much energy is required to transform solid water at 0 degrees Celsius to liquid at 0 degrees Celsius?
80cal/g
What is meant by the term absolute zero Why can't an object actually be that cold?
Absolute zero is the theoretical temperature of an object that has no kinetic energy. This is 0 on the Kelvin scale which relates to -273.15oC. Nothing can actually reach this temperature as to achieve a kinetic energy of 0 Joules, the object would have to be removed from the universe entirely.
