What is matter made of?
What is tiny moving particles called atoms
100
What is the law of conservation of energy?
What is energy cannot be created or destroyed, it can only change forms.
100
What is the difference between thermal energy and temperature?
What is Thermal energy is the total amount of kinetic energy and temperature is the average amount of kinetic energy
100
What is temperature?
What is A measure of the average kinetic energy of all the particles in an object
100
What is sublimation?
What is Sublimation is when a solid converts into a gas
200
All matter has what two qualities / characteristics?
What is have mass and take up space (volume)
200
One _________ is the amount of energy needed to raise the temperature of 1 gram of water by 1*C.
What is a Calorie
200
What is heat?
What is a measure of the flow of energy from an object at a higher temperature to an object that is at a lower temperature.
200
What is the difference between a calorie and a Calorie?
What is A Calorie is equal to 1000 calories (kilocalorie)
200
How do you solve for density?
What is Density = mass / volume
300
What is the smallest basic unit of matter?
What is an atom
300
What is the difference between kinetic and potential energy?
What is kinetic energy is energy in motion, potential energy is stored energy either due to chemical composition or position.
300
What is the equation for solving for heat?
What is H = m∆TCp
300
What does the kinetic theory of matter state?
What is All of the particles that make up matter are constantly in motion
300
How do you measure the volume of irregularly shaped objects?
What is Water displacement method
400
What is the difference between matter and mass?
What is Matter makes up everything, and mass is the amount of matter in an object
400
How is an object's kinetic energy determined?
What is by knowing the object's mass and speed
400
What are the three types of heat transfer, and explain each type.
What is convection- heat transfer in a liquid or gas rising and falling in a circular pattern due to changes in density. Conduction - transfer of heat through touch, and radiation - transfer of heat through waves
400
Explain what thermal expansion is and how this concept applies to thermometers
What is This is how liquid in a thermometer shows the temperature by rising due to a decrease in density in the liquid
400
What is the difference between mass and weight?
What is Mass describes the amount of matter in an object, weight describes how strongly gravity is pulling down on that matter
500
What are the four states of matter, and how do particles behave in each state?
What is solid (particles are moving very slowly, vibrating in place), liquid (particles interact with each other and can flow), gas (particles move freely, may collide but barely interact), plasma (particles are charged and can interact with each other over large distances)
500
Describe the transfer of energy needed in order to turn on a light bulb. Be as specific as possible
What is potential to mechanical in the arm of a person reaching for the switch. There is stored potential energy in the wires, when the switch is on that energy is converted into light energy by the filament of the light bulb and to heat energy which is an unwanted form of energy in this system.
500
Describe how an insulator works.
What is Insulators slow energy transfer of energy from areas with different amounts of energy (like the insulation in the walls of a building keep warm air in and cold air out)
500
What is the difference between endothermic and exothermic reactions?
What is Exothermic reactions release energy, endothermic reactions gain energy
500
What are the signs of a chemical change?
What is Production of an odor, change in temperature, change in color, formation of bubbles, formation of a solid
