Hey there!
A phase change is an example of a physical change.
This is because no new substance is formed. Physical changes affect the form of a substance, and can usually be reversed.
In a chemical change, the substance is changed and one or more new substances are formed.
Hope this helps!
Answer:
8.8 seconds
Explanation:
Formula: acceleration = (v - u) /t where v = final velocity, u = initial velocity and t = time
a = 2.5 m/s²
u = 5.0
v = 27. 0
t =?
at = v - u
t = (v - u) /a
= (27- 5)/ 2.5
= 8.8 s
