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.
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
Oh, dude, the manipulated variable in that scenario would be the shape of the ice cube. So, like, if you're testing how different shapes of ice cubes melt, you're basically playing with the shape to see how it affects the melting process. It's like science, but with ice cubes. Cool, right?
Forever if you leave them in the freezer! But it melts in hours.
Simply, the melting point. Think of an ice cube. The melting point is the temperature at which the ice cube MELTS into a liquid.
One catchy science fair project about melting ice could be investigating the effects of different substances, such as salt, sugar, or sand, on the rate of ice melting. Another idea could be studying how the shape or size of ice cubes affects their melting time. Additionally, you could explore how environmental factors, like temperature or humidity, impact the melting rate of ice. These projects would allow for hands-on experimentation and the opportunity to analyze and interpret data.
Due to their varying melting points (ice 32 and sugar 366°)
yes
Because when you add sugar to ice it is no longer ice it is 'sugar ice' and therefore has a different melting point from pure ice.
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.
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.
Yes, you can lift an ice cube with a string and sugar by creating a temporary bond between the sugar and the ice cube. When the sugar is poured onto the ice cube, it will partially dissolve and re-crystallize, forming a sticky bond with the string, allowing you to lift the ice cube.
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.
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.
Melting of ice is at 0 oC.
It depends how long the juice ice cube has been in the freezer or fridge, and it depends on how long the sugar ice cube has been sitting out
Temperature affects an ice cube by either melting it or freezing it. If the temperature is warmer than the ice cube's melting point, the ice will melt into water. If the temperature is colder than the ice cube's freezing point, the water will freeze and the ice cube will grow.
Because the melting temperature of the ice is 32°F and the melting temperature of the salt is 1,474°F.
