What is the arrangement of water molecules in the gaseous liquid and solid?
In a solid state, particles vibrate because there's not a lot of space for them to move in. A solid has a definite shape and volume. In a liquid state, particles flow past one another because there is no definite shape but there's a definite volume. In a gas state, particles move really fast because there's no definite shape or volume.
Do temperatures mesure how fast the particles of a substance are moving around?
True... Technically, yes. The faster the particles move, the more heat they give off. So therefore, when we actually take a temperature, it is in theory, the measrue of the speed of the particles. Improvement: Temperature is defined as the average kinetic energy of the particles in a particular substance. Kinetic energy is associated with the speed of particles by KE=(1/2)mv2. Particles do not technically 'give off heat' when they move since by laws of thermodynamics heat is a transfer of energy between substances and the term does not apply in this circumstance.
Why does a substance change states?
A change of state is accompanied by a change in an energy level, so it can be caused when energy is put into a substance, or taken out. As an example, when changing state from liquid to gas, that means that the individual particles have so much energy (or equivalently, move so fast) that they can escape from the attractive forces of other particles.
What are the two properties that determine the state of a substance?
gases have no shape,volume water has volume but no shape solids have shape and volume gases have the most intermolecular space solids have least inter molecular space <><><><><> Temperature and pressure.
As sample of matter is heated it's particles do what?
As the individual atoms are warmed up, they move faster causing the substance to expand slightly. As a substance has energy added to it through heating, its Kinetic Energy becomes greater. Kinetic energy is the energy of Motion - the more the kinetic energy of the atoms of a substance means the faster the speed of motion of these same atoms.
What is the measurement of how fast particles move in a substance?
It is measured as the thermodynamic temperature - the temp on the Kelvin scale.
What is a measure of the average energy of the particles in a substance?
Temperature is a measure of the average energy of the particles in a substance. It indicates how fast the particles are moving within the substance.
What substance has the most fast moving particles?
Photons
Is a measure of the average kinetic energy of the particles of a substance?
temperature
What is the meaning of thermal velocity?
Thermal velocity can be defined as the speed at which particles move to make up a gas, liquid, or other such substance. Thermal velocity is a measurement of temperature. This is a common term used in medicine research.
A measure of how fast the particles in an object moving is the?
The measure of how fast the particles in an object are moving is known as its temperature. Temperature is a representation of the average kinetic energy of particles in a substance.
What is measure of average speed of particles of a substance?
The average speed of particles in a substance is determined by calculating the total distance traveled by all particles over a certain time period, and then dividing by the number of particles. This provides a measure of how fast, on average, the particles are moving within the substance.
Is it true that a high temperature has particles that move quickly?
Not precisely. A temperature can't have particles. A substance which is at a high temperature has particles which are moving fast.
What is a measure of the average energy of the paricles of a substance?
The measure of the average energy of particles in a substance is called temperature. It is a representation of the kinetic energy of the particles in a system, describing how fast the particles are moving on average.
Does temperature measure how fast the particles of a substance are moving around?
Yes, temperature is a measure of the average kinetic energy of particles in a substance. When temperature increases, the particles move faster, and when it decreases, they move slower.
What happens at the particle level as a given volume of air is warmed?
the particles, as they are heated start to vibrate faster giving the particles of air to heat up. the more heat put into the the volume of air the faster the particles will vibrate. The more they vibrate the more pressure the particles create by their fast vibrations. Because the particles vibrate so fast they will hit the edge of the volume container making so much pressure eventually they will break the container and go free in the air.
What is a measure of the energy of motion of particles in a substance?
Temperature is a measure of the energy of motion of particles in a substance. It provides information about how fast the particles are moving within the substance.
