What else can I help you with?
Can you melt ice with a flashlight?
yes. if the flash light produces enough heat
How can I prevent my ice cream from melting quickly in the summer heat by using freezing ice?
To prevent ice cream from melting quickly in the summer heat, place the ice cream container in a larger container filled with ice. The cold temperature from the ice will help keep the ice cream cold and prevent it from melting too quickly.
How many joules of heat are necessary to melt 500g of ice at its freezing point?
The heat required to melt ice is called the heat of fusion, which is 334 J/g. To melt 500g of ice, you would need 334 J/g x 500g = 167000 joules of heat.
How many grams of ice are formed when 100 grams of steam turns to water then to ice?
To calculate the grams of ice formed from 100 grams of steam, we need to consider the heat exchange involved in the phase changes. First, the steam needs to lose heat to condense into water, then cool further to freeze into ice. Given the specific heat capacities and enthalpies of fusion/vaporization of water, you can determine the final mass of ice formed.
Does freezing gain thermal energy?
Yes. When ice is converted to water, thermal energy is required. When the water is converted back to ice, the same amount of thermal energy is released.
Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
How much heat is necessary to vaporize 500 grams of ice at its freezing point?
The heat required to vaporize 500 grams of ice at its freezing point is the sum of the heat required to raise the temperature of the ice to its melting point, the heat of fusion to melt the ice, the heat required to raise the temperature of water to its boiling point, and finally the heat of vaporization to vaporize the water. The specific heat capacity of ice, heat of fusion of ice, specific heat capacity of water, and heat of vaporization of water are all needed to perform the calculations.
Which phase or change involves a gain of 80 calories gram?
freezing, liquid to ice.
Is ice freezing endo or exothermic?
The process of ice freezing is exothermic. When water molecules lose energy and come together to form a solid structure, they release heat into the surroundings. This heat release is what we feel as the temperature decreases and the water turns into ice.
Why in ice cube at 0 degree Celsius is much effective in cooling a drink that the same mass of water at 0 degree Celsius what is the formula?
Latent heat of the ice, liquid water has no latent heat reserves. Perhaps at freezing we should call it "latent cold" but thermodynamics has always referred to it as latent heat whether at boiling or freezing. +++ It is latent heat because the water (liquid or ice) at freezing-point (0ºC) still contains heat energy as its temperature is at about 217ºK.
What determines if water is melting or freezing at 0 degrees Celsius?
At 0 degrees Celsius, whether water is melting or freezing depends on the direction of energy flow. Melting occurs when heat is added, while freezing occurs when heat is removed. If water is at exactly 0 degrees Celsius, adding heat will cause it to melt into liquid water, and removing heat will cause it to freeze into ice.
What makes ice melt?
When ice is kept at room temperature ( or above the freezing point ) heat from the environment interacts (goes inside it) with the molecules of ice.
What is it called when water turns into ice on the outside of a ice pop?
Freezing, if the ice pop hasn't got up to Oo C
What is the scientific name for ice forming and melting?
For forming it is Heat of (Fusion) and for melting its Heat of (Vaporization).
What is the difference between freezing and melting?
Melting is when you heat something up and it turns from a solid state into a liquid state, such as adding heat to ice (solid) melts it to water (liquid). Freezing is the opposite, so cooling a liquid until it becomes a solid.
When you are making ice cream do the changes of state is a release of heat or an absorption of heat?
Freezing is an exothermic phenomenon; the enthalpy of fsion is released.
How many joules of heat are necessary to melt 500 g of ice at it's freezing point?
Heat required to melt 1 g of ice at 0°C is approximately 80 cal . This is also called latent heat of fusion of ice.
