What is basic difference between melting and fusion?
Melting point is the temperature at which something melts. Like ice has a melting point of 0 Celsius. The heat of fusion is the heat energy that is absorbed (or released) when a substance melts (or freezes) an is measured in energy units, either calories or joules. Ex. One gram of ice must absorb 80 calories of heat energy to change into liquid water.
How much heat is released when 250 g of water at 10 degrees Celsius freezes into ice and cools to -10 degrees Celsius?
250g of water at 10C needs to lose 1 cal/g/C or 2500 calories to drop temperature to zero. The latent heat of fusion of water is 80 calories per gram at 0C so, the water needs to lose 20,000 calories to turn to ice at 0C Finally, the ice needs to lose 0.316 cal/g/C or 790 calories to drop to -10C The total heat released is then 2500 + 20,000 + 790 = 23,290 calories
If 405.0 ml of water had its temperature raised by 17.2 degrees celsius how many calories would have been put into the water?
I don't think you actually put calories into the water. You would dissipate thermal energy that could be measured in kCal or calories to heat the water. You may be thinking of the stored thermal energy from the heated water.
Does water freezes at -0c?
Yes, water freezes at 0°C
What happens to the volume of a water balloon when it freezes?
As the water freezes, it will expand.
When liquid water freezes into ice energy is absorbed or released or not involved?
Energy is released.
When the lake surface freezes in the winter how many calories of heat are released by each gram of water?
334
How do you get the energy released when 150 grams of water freezes?
You need to get the energy OUT of the water; otherwise it won't freeze. This is usually done by putting the water in contact with something colder.
The molar heat of fusion for water is 6.008 kJmol What quantity of heat energy is released when 253 g of liquid water freezes?
When the molar enthalpy of fusion for water is 6.008 kJ/mol, there is 84.4 kJ released when 253 grams of liquid water freezes. 84.4 kJ
How much energy is released when 65.8g of water freezes?
Hfus of water is 333.55 (333.55j/g)(65.8g)=21947.59J 21947.59/1000= 21.947kJ I think
When water freezes has energy been added?
Yes, energy has been added
What energy changes occur when water freezes?
When water freezes, it will go through an exothermic reaction, which is a chemical reaction that releases energy in the form of light or heat. It is expressed in a chemical equation as: reactants --> products + energy
What happens to the energy that is lost when water freezes?
It goes to the environment.
Water must contain calories not Calories which is 1000 calories otherwise Einstein is wrong about matter and energy being the same So how many calories in water?
There aren't any calories in pure water. Water doesn't give you energy, so therefore it doesn't have any calories.
Why does drinking milk supply your body with energy but water does not?
Milk contains calories which give you energy. Water doesn't contain calories.
