7 m/s
Explanation:
Acceleration,
Where v and u are the final and initial velocities of the Justine respectively, t is the time taken for Justin to attain final velocity.
Making v the subject then
v=at+u
Taking u as zero then
Substituting 3.5 for t, 2 as a then
v=3.5*2=7 m/s
Answer: The correct answer is-
liquid to solid.
The term exo in exothermic means outside the system whereas thermic means heat.
Exothermic process can be described as any chemical reaction that liberates energy in the surrounding in the form of heat.
In other words, when heat is liberated in the environment in a chemical reaction, it is said to be an exothermic reaction/process.
When liquid phase changes to solid phase (such as water to ice), heat is released/liberated in the surrounding.
Thus, it is an example of exothermic process.
