Topic 4

thermal energy

• the total kinetic and potential energy of all the particles in a substance.
• bridge joints
• the expansion of matter when it is heated
• not typically
• paper, gas, wood, fiberglass, blankets

What factors affect energy?

• temperature, amount of matter, state of matter
• the total kinetic and potential energy of all the particles in a substance.
• bridge joints
• the expansion of matter when it is heated
• not typically

What affects the relationship between the temperature and the total energy of a system?

• types, phases (states), and amounts of matter present
• temperature, amount of matter, state of matter
• the total kinetic and potential energy of all the particles in a substance.
• bridge joints
• the expansion of matter when it is heated

heat

• The transfer of thermal energy from a warmer object to a cooler object.
• types, phases (states), and amounts of matter present
• temperature, amount of matter, state of matter
• the total kinetic and potential energy of all the particles in a substance.
• bridge joints

How can the addition or removal of heat affect matter?

• It can make it change states.
• The transfer of thermal energy from a warmer object to a cooler object.
• types, phases (states), and amounts of matter present
• temperature, amount of matter, state of matter
• the total kinetic and potential energy of all the particles in a substance.

What's one example of heat transfer?

• coffee to mug to hand
• It can make it change states.
• The transfer of thermal energy from a warmer object to a cooler object.
• types, phases (states), and amounts of matter present
• temperature, amount of matter, state of matter

temperature

• A measure of how hot or cold something is, average kinetic energy of a substance
• coffee to mug to hand
• It can make it change states.
• The transfer of thermal energy from a warmer object to a cooler object.
• types, phases (states), and amounts of matter present

What units measure temperature?

• Celsius, Kelvin, Fahrenheit
• A measure of how hot or cold something is, average kinetic energy of a substance
• coffee to mug to hand
• It can make it change states.
• The transfer of thermal energy from a warmer object to a cooler object.

What affects the amount of energy needed to change the temperature of a sample?

• nature of the matter, mass of the sample, environment
• Celsius, Kelvin, Fahrenheit
• A measure of how hot or cold something is, average kinetic energy of a substance
• coffee to mug to hand
• It can make it change states.

Example of the amount of thermal energy

• If a cup and a kettle of tea are at the exact same temperature, the kettle has more thermal energy because it has more mass.
• nature of the matter, mass of the sample, environment
• Celsius, Kelvin, Fahrenheit
• A measure of how hot or cold something is, average kinetic energy of a substance
• coffee to mug to hand
