Does the number of particles change as the substance changes its state?
Answer:
no
Explanation:
No, the number of particles does not change as the substance changes its state. Change of state from one phase to another is achieved by providing or absorbing heat or pressure. For instance, liquid water if heated becomes vapour steam and if cooled becomes solid ice.

What are three ways that waves are measured, and which of these
measurements is associated with the energy and strength of a wave?
Crest - The highest point on the wave above the still-water line. Trough - The lowest point on the wave below the still-water line. Wave Height - The vertical distance between crest and trough. Wavelength - The horizontal distance between successive crests or troughs.
Scientists use the terms amplitude, wavelength, and frequency to refer to some commonly measured properties of waves.
How do light waves and sound waves compare ( CHOOSE 2 ANSWERS )

B Light waves are transverse and oscillate perpendicular to the direction of motion
C Light waves are longitudinal and oscillate perpendicular to the direction of motion
D Sound waves are transverse and oscillate in the same direction as the direction of motion.

where would the oldest rock be found
l m n o (science)
(includes cute drawing)
Answer:
O
Explanation:
Older rocks are usually found deep into one side of a formation.
Cute drawing btw :3
Based on the geologic column (diagram), the oldest rock would be found in: Layer O.
A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in an ascending order, usually from the youngest layer to the oldest.
In a geologic column, the youngest layer is usually at the top while the oldest layer is at the bottom.
Hence, each lower layer of a rock is older than the rock layers above it.
Based on the geologic column (diagram), the rock layer which is most likely to be the oldest rock is layer O because the youngest rock is at layer L i.e it sits on top (far left).

Why was it hard for the United States to avoid other nations’ problems?
due by 11:59pm helppp :''(
Answer:
Only a third of Americans are thought to hold passports -- compared to about 50 percent in Australia, more than 60 percent in Canada and some 80 percent in the United Kingdom. "
First of all, in order to travel even 500 miles from home in Europe, you need a passport, or at least you did until the EU got started.
In America, you can travel 500 miles from home for vacation very easily without one. And in Europe, it also doesn't cost an arm and a leg to take an international flight to visit a foreign country. You can hop a train or even drive. The average American faces hours of expensive plane or boat travel in order to go somewhere where a passport is required. I guess if you're made out of money you should have a passport, but millions of Americans don't live the kind of lifestyle where they can afford long-distance travel. (For some reason, this fact is really hard for jet-setting academics to get their minds around.)
For that matter, why would the average American want to go overseas, where they'll just be derided as a tourist? Sure, I would love to visit darkest Burma and hang out with some hill tribes, but pretty much the best that the average American can hope for, with the small amount of vacation time and money that they have for these things, is to not even get to Burma, and spend a weekend in Patpong.
Secondly...
"When they get wherever they are going, it is crucial that they live and study not just with other Americans, but also with local people of their own generation."
So basically they can go to Florence or London and party with other similarly entitled kids? You forgot "local people of a class other than their own."

Mike and Mariah are in the same science class. Mike wants to know how the water cycle transports energy and matter. Which of the following examples in Mariah's notebook should she share as the best example of how the water cycle transports both energy and matter?
Water transforms from a solid to a liquid to a gas.
Water transported through the water cycle is never created or lost.
Water vapor precipitates back into the ocean or the land after heating.
Water vapor rises into the air where colder temperatures cause it to condense and form clouds.
Answer:
Water vapor precipitates back into the ocean or the land after heating.
Explanation:
The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.
The statement which describes the matter and energy transport during water cycle is option c, water vapor precipitates back into the ocean or the land after heating.
What is water cycle ?Water cycle is a geological phenomenon through which the water content in the atmosphere and hydrosphere is balanced. The heat radiated from sun warm up the water bodies make the convection currents that evaporates water.
The water vapor rise to the atmosphere and maintain the air moisture. When this vapor cools down they condense and precipitates as rain, snow or sleek.
This process involves the transfer of heat energy and matter. Here, the matter is water itself with its three phases. Therefore, the statement which describes the matter and energy transfer is option c.
