How do evaporation and condensation relate to heat

Answers

Answer 1
Answer: Both of them are phase changes that result from the flow of heat. Evaporation happens when heat is added to a substance. Condensation happens when heat comes out of a substance.

Which of the following substances are NOT formed by chemical bonds?A. mixture
B. molecule
C. compound
D. pure substance

Answers

Answer:

The answer is D. pure substance.

Explanation:

A pure substance is a particular class of homogeneous matter whose composition is fixed and chemically defined, that is, it has a stable chemical composition since it is a matter that remains chemically unaltered in its different states of aggregation, endowed with properties singular and characteristic. A pure substance is composed of entities such as molecules, formular units and atoms.

Pure substance becuase if it is pure it is not a bond

A train is accelerating at a rate of 2 km/hr/s.  If its initial velocity is 20 km/hr, what is its velocity after 30 seconds?

Answers

"2 km/hr/s" means that in each second, its engines can increase its speed by 2 km/hr.

If it keeps doing that for 30 seconds, its speed has increased by 60 km/hr.

On top of the initial speed of 20 km/hr, that's 80 km/hr at the end of the 30 seconds.

This whole discussion is of speed, not velocity. Surely, in high school physics,
you've learned the difference by now. There's no information in the question that
says anything about the train's direction, and it was wrong to mention velocity in
the question.  This whole thing could have been taking place on a curved section
of track. If that were the case, it would have taken a team of ace engineers, cranking
their Curtas, to describe what was happening to the velocity.  Better to just stick with
speed.

The effects of agriculture and industry can be more harmful with the further loss of wetlands.

Answers

Yes, it is true that the effects of agriculture and industry can be more harmful with the further loss of wetlands since industry usually requires large amounts of land.

Explanation:

What is the density of water?
gram/mL
(fill in the number)

Answers

Answer:

1.00 gram per milliliter (1 g/mL). In other words, 1 milliliter of water has a mass of 1 gram. A drop of water is 0.05 mL of water, so its mass would be 0.05 grams.

Explanation:

In a transverse wave that travels through a medium, the molecules of the medium vibrateA. at right angles to the direction in which the wave travels.
B. at twice the velocity of the molecules in a longitudinal wave.
C. with smaller amplitudes than the molecules in a longitudinal wave.
D. in the direction in which the wave travels

Answers

So we wan't to know how the molecules of the medium vibrate when a transverse wave propagates trough that medium. A transverse wave is a wave whos oscilations are perpendicular to the direction of it's propagation. So the molecules in a medium will vibrate perpendicular to the direction of propagation of the wave. So if the wave is moving in the x-direction, the molecules will vibrate in the y-z plane. The correct answer is A. at right angles to the direction in which the wave propagates.

When driving downhill, your vehicle will accelerate and start moving fast, due to _______________.a. kinetic energy
b. gravity
c. the amount of pressure you put on the accelerator pedal
d. wet pavement

Answers

Correct answer choice is:

B) Gravity


Explanation:


Gravity is a force of attraction that endures within any two bodies, any two groups, any two particles. Gravity is not just the attraction among objects and the Earth. It is because the Earth going around the Sun is in a magnetic stability. The speed of the Earth's action generates a centrifugal force which balances the gravitational force among the Sun and the Earth. Because there is no force to hold it.

B: Gravity.
The force of gravity will pull the car down the hill. The weight/mass of the car also helps this.
