Yes when it is very hot
It is an example of change in the state of matter.
Yes, it's a physical change because melting ice or Bowling water isn't changing the fact that it is water in different states of matter.
Due to their varying melting points (ice 32 and sugar 366°)
Because melting sugar turns color to form caramel. i.e. it has changed and specifically it has undergone a CHEMICAL CHANGE (Or chemical reaction). When melting ice, no chemical reaction occurs, and so it is just a PHYSICAL CHANGE.
Yes, the mass of the ice cube remains the same after melting. This is because mass is conserved during a phase change, so the total amount of matter remains constant even though the state of the matter changes from solid to liquid.
Yes, it's a physical change because melting ice or bowling water isn't changing the fact that it is water in different states of matter.
A melting ice cube is a physical change, because the ice cube is only changing size, shape, volume and state of matter.It's not a chemical change, because it's not changing into a different kind of matter with different properties.
Sawdust can help insulate the ice cube and slow down the melting process, but it won't completely prevent the ice cube from melting. The insulating properties of the sawdust reduce the transfer of heat to the ice cube, which can help keep it colder for longer.
The size doesn't matter. What will matter is the shape. The more contact the outer layer has the faster heat can be transferred into the ice.
Melting of an ice cube mainly depends on the temperature of surrounding. If the larger ice cube is put at 50 degrees Celsius and small one at 25 degree Celsius the large ice cube will melt faster than the smaller one. Ice cube draws energy from the surrounding which causes it to melt and so temperature of surrounding is very important
UV light can contribute to the melting of an ice cube by transferring energy to the ice cube, causing it to absorb the energy and melt faster. The UV light can increase the temperature of the ice cube, accelerating the melting process compared to no exposure to UV light.
Cotton balls will not keep an ice cube from melting. While they may insulate the ice cube slightly, they are not effective at preventing the ice from melting due to their low heat conductivity. Placing the ice cube in a well-insulated container or using a more effective insulating material would be more effective in preventing the ice from melting.
