Answer:
Conduction heat transfer is the transfer of <em>heat by means of molecular excitement within a material without bulk motion</em> of the matter.
Explanation:
Conduction heat transfer in gases and liquids is due to the collisions and diffusion of the molecules during heir random motion.
<h2>Answer:</h2>
The correct answer is option D. Which is "Over time, the lawn has naturally become disorderly".
<h3>Explanation:</h3>
- Entropy, the measure of a system's thermal energy per unit temperature that is unavailable for doing useful work.
- It is also a measure of the molecular disorder, or randomness, of a system.
- According to above definitions of entropy option D is correct.
- <u>So entropy of system is randomness/disorder that is increasing with time in case of lawn.</u>
Explanation:
Initial velocity: Vi = Vf - (a * t)
Understand what each symbol stands for.
Vi stands for “initial velocity”
Vf stands for “final velocity”
a stands for “acceleration”
t stands for “time”
