5.1 The Nature of Heat
This Scottish Botanist is responsible for the first recorded observations and theory that eventually became known as Thermal Energy.
Robert Brown
Heat always flows from...
Hot to Cold
A microwave heats food up via this form of heat transfer.
Radiation
The rising of warm air and sinking of cold air forms these types of currents.
Convection Currents
The higher the heat capacity of an object is, the ______ it takes to change its temperature.
Longer
As we introduce heat to a liquid, the particles that make up that liquid do what?
Increase in motion/vibrate faster.
This form of energy is associated with the measure of motion particles have.
Kinetic Energy
This term describes the transfer of heat through direct contact of two objects.
Conduction
The amount of thermal energy required to raise the temperature of a substance by one degree Celsius is this property
Heat Capacity
This is the reason many handles of pots and other cooking utensils are generally made of woods and plastics because they have a ____________ than the metal that touches the heat source.
This American Count, was the first engineer who's observations served as the basis to describing friction.
Count Rumford
If two objects are the same temperature but object A is twice as large as object B, this object will have more Thermal Energy.
Object A
This transfer of heat can only occur in liquids and Gasses.
Convection
The warmer wind on cold nights that flows from the land towards the water is called this.
This fluid is pumped through a refrigerator and into a compressor to transfer the heat from inside the fridge to outside of it.
Coolant
Friction
This term describes the sum of all kinetic energies of all particles present in an object.
Heat (Thermal Energy)
This form of heat transfer involves vibrating electrons that travel in a wave.
Radiation
The cooling wind on hot days that flows from the water toward the land is called this.
Sea Breezes
This is the primary form of heat transfer used in oven to heat food.
Convection
This term describes the vibrating motion of particles that increases as temperature increases.
Brownian Motion
This term describes the average of all kinetic energies of all particles in an object.
Temperature
Warm molecules are farther apart than colder ones, this means they are less dense than colder ones. This phenomenon causes those warmer molecules to do move in what direction?
Rise Up
Large bodies of water are capable of regulating climates due to this property.
Its high Heat Capacity.
This is the primary form of heat transfer is utilized in radiators to cool a combustion engine.
