Temperature
The measure of how hot or cold something is?
What is temperature?
It is the total kinetic energy of the particles in a substance.
What is thermal energy?
It is the process of transferring energy from one object or system to another.
What is energy transfer?
Kinetic, potential, thermal, chemical, electrical, nuclear, and mechanical energy.
What are the different forms of energy?
A thermal system is a collection of matter that can exchange thermal energy with its surroundings.
What is a thermal system?
The tool do we use to measure temperature?
What is a thermometer?
Thermal energy refers to the total energy of all the particles in a substance, while temperature measures the average kinetic energy of those particles.
How does thermal energy differ from temperature?
Conduction, convection, or radiation.
What is Name one method of energy transfer?
What is to Identify the type of energy stored in food?
Changes in thermal energy can cause matter to change states, such as solid to liquid (melting) or liquid to gas (evaporation).
How does thermal energy affect the state of matter
Celsius is a metric scale where water freezes at 0°C and boils at 100°C, while Fahrenheit is a scale where water freezes at 32°F and boils at 212°F.
How to explain the difference between Celsius and Fahrenheit.
Name a real-life example where thermal energy is important.
What is Cooking food?
Conduction transfers energy through direct contact between materials, where faster-moving particles collide with slower-moving particles
How does conduction transfer energy?
Kinetic energy
What type of energy is associated with an object's motion?
Thermal energy drives weather patterns by causing air movement and influencing temperature and moisture levels.
What role does thermal energy play in weather systems?
: The temperature increases.
What happens to the temperature of a substance when it absorbs heat?
More mass generally means more thermal energy because there are more particles contributing to the total energy.
What is the relationship between mass and thermal energy?
In convection, warmer water rises while cooler water sinks, creating a circulation pattern that distributes heat.
How convection works in heating water?
What is to explain potential energy?
Insulation slows down the transfer of thermal energy, keeping heat in or out of a system.
What is to describe how insulation works in a thermal system.
Absolute zero is the theoretical temperature at which a substance has minimum thermal energy, defined as 0 Kelvin or -273.15°C.
What is to describe absolute zero.
During a phase change, thermal energy is absorbed or released without a change in temperature, such as when ice melts to water.
What is to explain how thermal energy is transferred in a phase change?
Radiation is the transfer of energy through electromagnetic waves, such as sunlight warming the Earth.
What Explains radiation in terms of energy transfer?
Kinetic energy is the energy of motion; for example, a moving car has kinetic energy.
What is to describe kinetic energy and provide an example.
Engines convert thermal energy from fuel combustion into mechanical energy to perform work.
What is to explain how thermal energy is involved in engines.
