ice cube melts in 10 seconds

However it also gets very, very cold at night, this may keep the ice cube from melting. Try the experiment with one normal ice cube and one colored ice cube, both in salt water and in tap water. Initially, the surface area of ice melting in air and ice melting in water is the same, but as the ice melts in air, a thin layer of water results. Record the results. The dashes will start to light up one at a time. One wonders if it is really worthwhile to spend time addressing a question that is phrased without any specified conditions, and is therefore impossible to answer. The second page of the recording sheet has some follow up questions to answer. Try adding solids of your own choice and record that data too. - Greg Baxley (age 31) Bakersfield College, CA Procedure. It is like asking: How far is up? Hi, your answer for why ice melts faster in salt water vs. tap water is not correct. The ice cube in the cup containing the fresh water will melt faster, because the (fresh) melt water is colder than the room-temperature fresh water in the cup. EXTENSION: Use a timer and record how long it took each material to melt the ice. If you place water and an ice cube in a cup so that the cup is entirely full to the brim, what happens to the level of water as the ice melts? the sun is so hot in the desert therefore they can melt within 30 seconds. However, here is a comment. yes they do. You will find the results interesting. Then draw your conclusions. This is why an ice cube melts more quickly on the outside and retains its coldness and solidity longer at the center: melting is a cooling process. The melting of ice is complicated by several things. 3: Set the timer to check back on the ice cubes every 10 minutes over 1/2 hour and record your results. The control ice cube … What caused the ice to melt fastest? This layer absorbs some of the heat from the air and has a slight insulating effect on the remaining ice. Kids will need to touch them some to observe them, but excessive handling will melt them, obviously! Ice melts when heat energy causes the molecules to move faster, breaking the hydrogen bonds between molecules to form liquid water. Thus, larger ice blocks melt at a much slower rate than cubed ice. Our longest lasting ice cube (in styrofoam) lasted for 3 hours and 20 minutes! Please push that big button holding it down for 10 seconds. Into each drinking glass place one ice cube. In the melting process, the water molecules actually absorb energy. It does have to do with density, but not in how high something floats. An advantage of using large ice blocks is that they have less surface area exposed to warmer outside air than smaller ice cubes. Hence its density is higher and it sinks to the bottom of the cup, being replaced by warmer waters at the ice cube. The volume remains the same when the ice cube melts. Make sure the ice cube is oriented the same way in each glass.
