2 kg * 1000 g/kg * 1mol/18.02 * 6.03 kj/mol = 669kj apex :D
2 kg * 1000 g/kg * 1mol/18.02 * 6.03 kj/mol = 669kj apex :D
To melt 2kg of ice, you need to add 334,000 joules of energy. This is known as the latent heat of fusion for ice, which is 334,000 J/kg. So, for 2kg of ice, the total energy required would be 668,000 joules.
Q = ( m ) ( L sub fusion ) = ( 2 kg ) ( 63 kJ/kg ) = 126 kJ <-----------------------
It takes about 80 calories to melt a gram of ice, so melting 2 kg of ice would take about 160 kilocalories.
How much energy is required to melt 10g of ice?
The energy required to melt ice is known as the heat of fusion, which is about 334 joules per gram. Therefore, it would take approximately 3340 joules of energy to melt 10g of ice.
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
What is added to ice to make it melt and how does this affect the molecules in the ice?
Heat is added to ice to make it melt. When heat is applied, it increases the kinetic energy of the molecules in the ice, causing them to break free from their rigid structure and turn into liquid water.
Would ice cubes melt in hot water first or will the ice cubes freeze the water first?
The ice cubes will melt in the hot water first. The heat energy from the hot water will transfer to the ice cubes, causing them to melt.
Why will a hot spoon melt ice cream faster than a cold one?
A hot spoon heats the ice cream at a faster rate due to increased thermal energy transfer, causing the ice cream to melt quicker. The cold spoon, on the other hand, has lower thermal energy, resulting in a slower melting process.
How much energy is required to melt 10g of ice?
The energy required to melt ice is known as the heat of fusion, which is about 334 joules per gram. Therefore, it would take approximately 3340 joules of energy to melt 10g of ice.
How much energy does it take to melt a 16.87 g ice cube?
It takes about 334 J/g to melt ice. So, to melt a 16.87 g ice cube, you would need about 5635.58 J of energy.
How much energy is needed to melt g of ice at 0 Celsius?
To melt 1 gram of ice at 0Ā°C, it requires 334 joules of energy. So for g grams of ice, the energy needed would be g multiplied by 334 joules.
How much energy does it take to melt ice?
Heat because Ice and water would thaw out and begin to heat up
How much energy would be required to melt 32.0 g of ice?
The amount of energy required to melt ice can be calculated using the equation: energy = mass of ice * heat of fusion. The heat of fusion for ice is 334 J/g, so for 32.0 g of ice, the energy required would be 32.0 g * 334 J/g = 10,688 J.
How many photons at 660 nm must be absorbed to melt 5.0 x 10 x10 g of ice?
To calculate the number of photons needed to melt the ice, you would need to determine the energy required to melt the ice and then convert that energy into photons at 660 nm. This involves calculating the energy required to melt the ice using the heat of fusion of ice and then dividing that by the energy of a photon at 660 nm.
How much energy does it take to melt 2 kg of ice (Refer to table of constants for water.?
The specific heat capacity of ice is 2.09 J/gĀ°C and the heat of fusion of ice is 334 J/g. To melt 2 kg of ice, you first need to heat the ice from -30Ā°C to 0Ā°C, then provide energy to melt the ice at 0Ā°C. The total energy required is 9836 J + 66800 J = 76636 J.
How many calories are required to melt a 1.52 g ice cube?
To melt 1.52 g of ice, you need to provide 6.4 calories of heat energy per gram of ice. Therefore, to melt a 1.52 g ice cube, you would need 9.73 calories of heat energy.
If ice is place on wood how long will it take to melt?
It would take longer because wood is an insulator, but it all depends on how much energy is absorbed by it's surroundings. If it's warm out, more energy can be used to melt the ice, if it is colder, then vice versa. If it is below freezing outside, then obviously it won't melt.
An ice cube melts when mechanical energy increases?
An ice cube will melt when it is above the freezing point of water. At this point the individual molecules have enough energy to vibrate more causing the ice cube to melt.
How long does it take to melt ice cube with ice melt?
that depends on the size of the ice cube, how much salt, and the ambient temperature.
What can changes energy?
Energy can change state of matter. Heat can be used to melt ice.
