Answer:
This is a chemical property. If iron does rust, this is a slow chemical change since rust is an iron oxide with different properties than iron metal.

Answer:
11.4 m
Explanation:
We are given that
Total distance traveled by cab,d=214 m
Maximum speed of cab=v=315 m/min=
1 min =60 s
Acceleration of cab=
We have to find the distance traveled by the cab while accelerating to full speed from rest.
Initial speed o f cab=u=0
Substitute the values in the formula
Hence, the cab travel 11.4 m from rest to full speed.
I believe the answer is C
<span>1.the higher the temperature of something, the greater its thermal energy.
2. the change in state from gas to liquid is called evaporation.
3. energy that comes from bonds within matter is called chemical energy.
4. the change in state from liquid to gas is called vaporization.
5. gas bubbles forming throughout the liquid is called boiling.
6. liquid changing to gas only at the surface is called evaporation.
7. the change in state from solid to liquid is called melting.
8. the change in state from liquid to solid is called freezing.
9. the law of conservation states that during any change, the amount of energy stays the same
10. another term for a chemical change is a chemical reaction
11. in sublimation, particles pass directly from solid to gas</span>
There ya go, Champ. Now you have all the answers and you haven't
