A teacher listed the following two processes.• Process 1: water changing to ice in a refrigerator
• Process 2: steam coming out of a kettle filled with hot of water

Which table correctly identifies the change of state taking place in each example?
A)
Process Phase Change
1 Liquid to gas
2 Liquid to gas
B)
Process Phase Change
1 Liquid to gas
2 Liquid to solid
C)
Process Phase Change
1 Liquid to gas
2 Gas to Liquid
D)
Process Phase Change
1 Liquid to solid
2 Liquid to gas

Answers

Answer 1

Answer: The answer is D because water changing to ice is liquid to solid and water turning to gas is liquid to gas.

Answer 2

Answer: so we know that water is a liquid, ice is a solid (block) and steam is a gas. With this information, change out the process and see which is true (I will check your answer if you comment below)

PLEASE HELP!!!!! :D The Sun rotates faster at its center than at its poles. Which statement in this passage describes the reason for this behavior? Similar to Earth, the Sun rotates around an axis that passes through its center. But unlike Earth, the Sun rotates faster at its center than at its poles. That’s because Earth is a solid mass, while the Sun is a gaseous globe. The Sun’s poles take about 34 days to rotate completely, and the equator takes about 26 days to complete one rotation. i need to choose one please help me!!! :P

Explain why atmospheric pressure changes as atmospheric depth changes.

Answers

the lower you go in relation to the top of the atmosphere the larger the column of air is that is pressing down on you.

Answer:

The force of the collisions creates pressure on the container. ... Explain why atmospheric pressure changes as depth changes. Atmospheric pressure increases as depth increases because at lower levels of the atmosphere, there is more air above that is being pulled down by gravitational force.

A fighter bomber is making a bombing run flying horizontally at 500 knots (256m/s) at an altitude of 100.0m. a) How long will it take for the bomb to hit the ground after it is dropped from the plane?

b) How far will the bomb go over the ground (in the x direction) before it hits the target?

Answers

Answer:

(a) t = 4.52 sec

(b) X = 1,156.49 m

Explanation:

Horizontal Launching

If an object is launched horizontally, its initial speed is zero in the y-coordinate and the horizontal component of the velocity $v_o$ remains the same in time. The distance x is computed as.

$\displaystyle x=v_o.t$

(a)

The vertical component of the velocity $v_y$ starts from zero and gradually starts to increase due to the acceleration of gravity as follows

$v_y=gt$

This means the vertical height is computed by

$\displaystyle h=h_o-(gt^2)/(2)$

Where $h_o$ is the initial height. Our fighter bomber is 100 m high, so we can compute the time the bomb needs to reach the ground by solving the above equation for t knowing h=0
