Which best compares freezing and condensation?

2 answers:

4 0

Condensation is a change of state from vapour to liquid while freezing is also a change of state, from liquid to solid. Both are change of states.

Additionally, condensation requires much more energy to change the state of vapor to liquid than it does it change the state of liquid to solid.

Answer:

C. Both involve the release of heat.

Explanation:

The change in state from liquid to solid (freezing) changes to a state of matter where atoms slow down. This also happens in the change in state from gas to liquid (condensation). The change in this movement is released as heat.

Gennadij [26K]

Answer:

15.2 s

Explanation:

Convert hp to W:

55.0 hp × 746 W/hp = 41,030 W

Power = energy / time

41030 W = 6.22×10⁵ J / t

t = 15.2 s

Here when car in front of us applied brakes then it is slowing down due to frictional force on it

So here we can say that friction force on the car front of our car is given as

$F_f = \mu m g$

So the acceleration of car due to friction is given as

$F_{net} = - \mu mg$

$a = \frac{F_{net}}{m}$

$a = -\mu g$

now it is given that

$\mu = 0.868$

$g = 9.81 m/s^2$

so here we have

$a = -0.868 * 9.81$

$a = -8.52 m/s^2$

so the car will accelerate due to brakes by a = - 8.52 m/s^2

How long will it take the ball to reach the height of 35m?

Verizon [17]

Ahhh... hello! I’ve done a science experiment that has asked this sort of question. Not as easy as it sounds... I know. I’ll tell you what I learned from that experiment. The answer will depend on the materials the ball is made of and then also your drop length. After these two things are determined, you can get a pretty close time and measurement. I hope this information helps. Have a great night!
