Which statement accurately describes what happens when water turns to steam in terms of energy?
The water absorbs energy which causes the water molecules to have more kinetic and potential energy, changing their configuration from a liquid to a gas.
The water absorbs energy which causes chemical bonds to break, changing water to steam.
The water releases energy which causes chemical bonds to break, changing water to steam.
The water releases energy which causes the water molecules to have less kinetic and potential energy, changing their configuration from liquid to gas.
Answer:
The water absorbs energy which causes chemical bonds to break, changing water to steam.
Explanation:
In a heat engine, if 500 J of heat enters the system, and the piston does 300 J of work.
What is the final internal (thermal) energy of the system if the initial energy is 1,500 J?
200 J
800 J
1,300 J
1,700 J
Answer: The final answer is 1,700 J
Explanation: According to first law of thermodynamics:
=Final energy-initial energy=Change in internal energy
q = heat absorbed or released
w = work done by or on the system
w = work done by the system= {Work done by the system is negative as the final volume is greater than initial volume}
q = +500J {Heat absorbed by the system is positive}
w = work done by the system = -300J
U2- 1500J= + 500J --300J
U2= 1700J
If the thermal energy of the system increases by 400 J, and 1,100 J of heat were added to the system, how much work did the system do?
400 J
700 J
1,100 J
1,500 J
Answer:
700 j

Darwin observed fossils of glyptodonts, which are now extinct. Living armadillos are the only animals remaining on Earth that are similar to glyptodonts. Armadillos live in the same places that glyptodonts lived.
What did Darwin most likely conclude about the two types of animals?
Glyptodonts were better adapted to the environment.
Glyptodonts outcompeted armadillos for food.
Glyptodonts were early relatives of armadillos.
Glyptodonts had the exact same adaptations as armadillos.
Answer:
3. Glyptodons were early relatives of armadillos.
Explanation:
Darwin would have come to this conclusion because glyptodons over time became armadillos, which you can tell by evolution that they were better evolved to survive than glyptodons. Due to this, they outlived the glyptodons.
Answer:
C Glyptodons were early relatives of armadillos.
Explanation:
Darwin would have come to this conclusion because glyptodons over time became armadillos, which you can tell by evolution that they were better evolved to survive than glyptodons. Due to this, they outlived the glyptodons.

during a full moon.
Where on the diagram should the student place the moon to accurately show its
position relative to the Earth and the sun during a full moon? A.1 B.2 C.3 D.4
To depict the positions of the Earth, the Moon, and the Sun during a full moon, a student is creating a diagram. The moon should be placed before earth. The correct option is D.4
What is a full moon day?A natural satellite is a moon. The moon orbits the planets. On each planet, there are a variable number of moons, ranging from only one on Jupiter to numerous on Earth.
The moon's various phases are visible in various parts of Earth as it orbits the planet. There are many shapes like the moon is full, C-shaped or crescent moon and no moon.
Full moon day is when the moon is fully visible to the earth. The round moon. It happens every 28 days.
Therefore, in the diagram, the moon will be placed at the number 4, before, the earth. The correct option is D.4

This question is about light transmission.
Answer:
When light hits an object, it is transmitted, absorbed, and/or reflected. The light on the left is reflected, the light in the middle is absorbed and the light on the right is transmitted. Any object you can see must at least partially reflect light to your eyes. Objects can ALSO absorb and/or transmit light.

Answer:
What happens: The copper wire will spin around. When the wire touches the top of the battery and the magnet, it is making a circuit, which allows electrons to flow – this is the current. ... This force, which is called a Lorentz Force, acts on the wire and causes it to move, which makes the wire spin around.
