1.How Does Heat Affect A System?
it makes the system work and makes it work faster.

did you hear about that guy that got frozen to absolute zero?
he's OK now
200
The increase in the volume of a substance when the temperature of a substance increases.
What is Thermal expansion
200
the total kinetic energy of the particles that make up a substance.
What is Thermal energy?
200
what kind of change is a change in state
physical

2.What Forms Of Energy Are Related To Particles?
All forms of energy are related to particles. In thermal and kinetic energy particles are affected by heat. the particles are always moving.
200
a thermometer reads 77 degrees Fahrenheit. what is this in Celsius
25 degrees Celsius
300
what does temperature tell you?
the average kinetic energy of the particles in an object
300
3 ways thermal energy is transferred
conduction, convection, and radiation
300
the amount of energy and heat in our food is measured by...
Calorimeter
300
3.How Is Energy Conserved During A Transformation?
In a physical change of state energy is conserved because only enough energy is used to change the state, not it's temperature. In a chemical change energy is given off and needed when new bonds are formed.
300
2grams of water is heated. before you heat the temp is 40 degrees Celsius and after is 100 degrees Celsius. how much heat was transferred to the water. ( specific heat of water is 4,184 J/kg
502,080 J
400
particles with more kinetic energy have a higher...
Temperature
400
explain what happens to the energy when two objects with different temperatures come into contact
energy moves from warmer object to cooler object until they are the same temp
400
what kind of change happens when one or substances combine to make new ones
chemical change
400
4.What Determines The Temperature Of An Object?
the amount of kinetic energy that the object has. the more energy the higher the temperature
400
What is the energy content of a food that releases 523,000J of heat
125 calories
500
name 3 objects that require of thermal expansion
hot air balloons, thermostat, expansion joints on cars
500
what is the difference between a thermal conductor and thermal insulator
a conductor transfers energy easily and an insulator does not
500
during a change of state, why doesn't the temperature of the substance change
energy is being used to change the state not the temperature
500
5. How Is Thermal Energy Different From Temperature?? 6. How Is Heat Transferred?
1. temperature is an average of the kinetic energy of an object. thermal energy is measured in joules and is the total kinetic energy in an object 2. conduction- when two objects touch energy is transferred convection- transferred by the movement of liquid or gas conductors( easily transferred)and insulators (not easily transferred) radiation- transferred by electromagnetic waves.
