Quide Questions? 1. What are the properties of ice cubes before letting them sit for 3-5 minutea in a room temperature? (Room temperature is higher than the temperature in the refrigerator. Thus, heat is absorbed by ice cu bes) 2. What happened to the ice cubes when they are exposed to heat? 3. What change in phase happened when ice cubes are heated? Describe the changes that happen in ice cubes when they are heat- ed? 5. What do you call this process of changing solid into liquid? 6. Are there new products formed when ice cubes melt? 7. Draw your observations before and after heating

Answer:
1. What are the properties of ice cubes before letting them sit for 3 5 minutes? The solid ice particles absorb heat energy from the warmer air, giving the particles energy and enabling them to move away from one another. Liquid particles still touch each other, but they are further apart than solid particles
2.The solid ice particles absorb heat energy from the warmer air, giving the particles energy and enabling them to move away from one another. ... This is what happens when the ice cube (a solid) turns into water (a liquid)
3.The ice cubes are at the melting temperature of 0ºC. Heat is transferred from the soda to the ice for melting. Melting of ice occurs in two steps: first the phase change occurs and solid (ice) transforms into liquid water at the melting temperature, then the temperature of this water rises
5.The process of a solid becoming a liquid is called melting (an older term that you may see sometimes is fusion). ... For any pure substance, the temperature at which melting occurs — known as the melting point — is a characteristic of that substance. It requires energy for a solid to melt into a liquid.
6.As an ice cube melts, its shape changes as it acquires the ability to flow. However, its composition does not change. A physical change is a change to a sample of matter in which some properties of the material change, but the identity of the matter does not.

Answer:
1.The weight does not melt the ice, it's the heat from inside the weight that melts the ice. Ice is 0 degrees farenheit, anything that touches it has a higher temperature. Water has a higher temperature, and the weight has a temperature of the room it is in.
