Question

physical properties of matter practice ---use the list above to help answer the questions below. 1. a spoon is placed in hot soup, and the handle quickly becomes warm. which physical property of matter is being demonstrated in this scenario? 2. a scientist heats ice until it changes into liquid water. which physical property of matter is being demonstrated in this scenario? 3. a student connects a wire to a light - bulb and battery. the bulb lights when a metal strip is added, but not when a rubber strip is used. which physical property of matter is being demonstrated in this scenario? 4. two unknown powders are tested. one sinks in oil, while the other floats. which physical property of matter is being demonstrated in this scenario?

Explanation:

1. Heat conduction is the transfer of heat through a material. When a spoon in hot soup warms up, it shows the physical property of heat - conduction.
2. Changing a solid (ice) into a liquid (water) by heating demonstrates the physical property of melting or change of state.
3. Conductivity is the ability of a material to conduct electricity. Since the metal strip allows the bulb to light up and the rubber strip does not, it shows the difference in electrical conductivity between the two materials.
4. Density is the mass per unit volume of a substance. The fact that one powder sinks and the other floats in oil shows a difference in density between the two powders.

Answer:

1. Heat - conduction
2. Change of state (melting)
3. Electrical conductivity
4. Density
