Readers ask: Why Does Water Behave In This Unusual Fashion?

What is the property of fluids which enables ships and balloons to float?

The principle that is behind floating objects is Archimedes’ principle: A fluid (liquid or gas) exerts a buoyant force, opposite apparent gravity (i.e. gravity + acceleration of fluid) on an immersed object that is equal to the weight of the displaced fluid.

Which term states that matter is made up of small particles that are in constant motion?

The kinetic theory of matter (particle theory) says that all matter consists of many, very small particles which are constantly moving or in a continual state of motion. The degree to which the particles move is determined by the amount of energy they have and their relationship to other particles.

Is the spreading of particles throughout a given volume?

the particles of this spread out and fill container. Particles require energy to overcome this force. Diffusion. the spreading of particles throughout a given volume until they are evenly distributed.

What is high temperature gas and positively and negatively charged?

A plasma is generally a mix of these positively charged ions and negatively charged electrons. Most plasmas are created when extra energy is added to a gas, knocking electrons free from atoms. High temperatures often cause plasmas to form.

What is a fluid that flows very slowly?

Viscosity. A liquid that flows very slowly is said to be more viscous than a liquid that flows easily and quickly. A substance with low viscosity is considered to be thinner than a substance with higher viscosity, which is usually thought of as being thicker. For example, honey is more viscous than water.

What is required for an object to float in water?

An object floats when the weight force on the object is balanced by the upward push of the water on the object. If the weight force down is larger than the upward push of the water on the object then the object will sink.

What is called Brownian motion?

Brownian motion, also called Brownian movement, any of various physical phenomena in which some quantity is constantly undergoing small, random fluctuations. It was named for the Scottish botanist Robert Brown, the first to study such fluctuations (1827).

What are 3 basic properties of matter?

1. The three basic properties of matter are volume, mass, and shape. 2. All matter is made up of tiny particles called atoms.

What is the most common state of matter in the universe?

The most common state in the Universe is plasma. This is because most of the atomic matter in the Universe is found in stars and stars are massive, extremely hot balls of ionised gas or plasma.

What are 3 examples of a gas?

Examples of Gases

  • Hydrogen.
  • Nitrogen.
  • Oxygen.
  • Carbon Dioxide.
  • Carbon Monoxide.
  • Water Vapour.
  • Helium.
  • Neon.

Do liquids assume the volume of their container?

A liquid has a distinct volume but assumes the shape of its container. A solid has definite shape and volume, regardless of its container. In the case of H20 steam is a gas, water is a liquid and ice is a solid. So in a smaller container it can be compressed, if the container is larger then it will expand.

Why do gases expand to fill the container?

Gases are in rapid motion, and they undergo elastic collisions with each other and the walls of the container; that is, momentum and energy is transfered not lost during collisions. Gases expand spontaneously to fill any container (rapid motion).

What is it called when gas turns into plasma?

Ionization (Gas → Plasma)

What is the 5th state of matter?

There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago.

Which best explains why a crystal is incompressible?

Particles in the plasma move randomly, but particles in a solid vibrate in one place. Which best explains why a crystal is incompressible? Its molecules remain in position without vibrating. The molecules of a crystal behave like those of a gas.
