Temperature, Thermal Energy, Heat
This is the measure of the average kinetic energy of a substance.
What is Temperature?
This is the temperature in Kelvin at 0 degrees Celsius.
What is 273 K?
This is the transfer of thermal energy that occurs between two objects in contact. (Why a metal spoon gets hot in boiling water)
What is conduction?
This is a device that transforms radiant energy from the sun into thermal energy.
What is a solar collector?
This is the instrument we use to measure the kinetic energy of a substance.
What is a thermometer?
True or False: A substance with a high specific heat will get hot very quickly with little energy.
What is False?
This is the temperature in Fahrenheit at 0 degrees Celsius.
What is 32 degrees Fahrenheit?
This is the transfer of thermal energy via fluid like water or air.
What is convection?
This is the study of the relationships between thermal energy, heat, and work (an engineers best friend)
This is the direction a convection current will go when you heat an object.
What is upward? (Heat rises)
This is the energy that is transferred between objects due to a temperature difference between those objects.
What is heat?
This the change in thermal energy of air in a room when it has a mass of 50 kg, a specific heat of 1000 J/(kg*C), and is warmed from 20-30 degrees Celsius.
What is 500,000 Joules?
This is the transfer of thermal energy that comes from the sun or flames.
What is radiation?
This is a device that transforms thermal energy into mechanical energy.
What is a heat engine?
What is high specific heat?
This property of water makes it a good coolant.
What is high specific heat?
This is the specific heat of a substance that weighs 1 kg has been heated with 46,046 Joules of thermal energy and increased in temperature 11 degrees Celsius.
Bonus points if you identify the substance.
What is 4186 J/kgC
Water
An object which thermal energy moves slowly is known as this.
This is a device that does work to transfer thermal energy from a cooler area to a warmer area.
What is a refridgerator?
This is the primary form of heat transfer a radiator uses to heat your home.
What is convection?
Explain which greater amount of thermal energy: one liter of water at 25 degrees Celsius or two liters of water at 25 degrees Celsius.
What is two liters of water? (greater mass)
This is the final temperature of a wooden block that was heated from an initial temperature of 20 degrees Celsius with 2130 Joules of thermal energy, has a mass of 0.2 kg, and a specific heat of 710 J/kgC.
What is 35 degrees Celsius?
Explain how radiation, conduction, and convection work together to create climates and weather. Hint: It they work in the order I've presented them.
Can be a verbal explanation.
Radiation heats the Earth's surface
Conduction from the ground heats the air above it.
Warm air rises through convection, and cools back to the ground, creating weather patterns.
This is the law that states energy will spontaneously flow from high concentration to low concentration.
What is the 2nd law of thermodynamics?
After several days of snowfall, a home with no snow on the roof is considered __________ insulated for thermal energy.
What is poorly?
