Phases of matter
This is the most dense phase of matter with the least amount of energy
Solid
The flat portion of a heating curve represents a..
Phase change or phase equilibrium
This type of energy is associated with temperature and the random movement of particles
Kinetic energy
An ideal gas exists only under these conditions
High temperature and low pressure
Using the information on your reference tables; The mass of a boiling sample of water is 1g, what is the heat of a sample?
2260 J/g
This phase of matter has just enough energy so that molecules or particles can 'roll' over each other.
Liquid
The incline on a heating curve represents..
This type of energy is associated with the molecular position and links(bonds) between molecules in the sample
Potential energy
A solid exists under these conditions
low temperature and high pressure
Using the information on you reference table; The mass of a freezing sample of water is 1g. What is the heat associated with the sample?
334 J/g
This phase of matter takes both the volume and shape of the container its in.
Gas
This type of energy increases on a heating curve during a plateau
Potential energy
This type of change does not change the chemical makeup of the substance. Through the correct processes you would be able to retrieve the original substance.
Physical change
This theory describes the relationships of pressure, volume, temperature among two samples or situations of gases
ideal gas law
At constant temperature the volume of a container is 5 L at 1 atm. If the pressure what increased to 2 atm, what is the volume of the container
2.5 L
This molecule breaks this rule; the solid form of a substance is the most compact (dense) phase
Water
This type of energy decreases on a cooling curve during a decline
Kinetic energy
This type of change occurs during a chemical reaction and will change the makeup of a substance.
chemical change
This theory states that gases are in random, constant, straight-line motion, are separated by great distances relative to their size; the volume of the gas particles is considered negligible, have no attractive forces between them
Kinetic molecular theory
A sample of 5 g of water increases from 10 to 20 degrees Celsius. What is the heat?
209 J
This phase of matter takes the shape of it's container but cannot be compressed
liquid
Phase equilibrium will happen to water at what two temperatures?
0 and 100 degrees Celsius
Heat always goes from a body with a higher temperature to a body with a__________
Lower temperature
What theory says that gases have collisions that may result in a transfer of energy between gas particles, but the total energy of the system remains constant.
Kinetic molecular theory
The temperature of a 10 L sample at 1 atm changes from 273 K to 373 K. If the pressure remains constant what is the new volume?
13.66 L
