Heat affects substances in different ways First, it changes the temperature of an object If heat is transferred from an object to the surroundings, then the
Explain how heat energy is transferred by convection, conduction, and/or radiation The temperature of objects transferring thermal energy is
One thing drives heat transfers it is a difference in temperature contact between substances Sight line - Can the objects “see” one another?
Conduction occurs when two substances at different temperatures are in contact Energy is always transferred from the substance with the higher temperature to
increasing the internal energy through heat transfer (e g As the temperature of substance passes through certain between two bodies at T
thermal energy is required to raise the temperature of different substances energy from warm water can transfer into a substance submerged in the
Temperature, Heat and Energy Transfer · Temperature · Thermal Energy Thermal Expansion As the temperature of a substance increases, its molecules
Heat is not a substance; it is a form of energy energy that is being transferred from one place to another between particles that touch
Problem Statement: How is heat transferred between substances? I Data Collection water starting at different temperatures?
increasing the internal energy through heat transfer (e g the discussion to heat transfer (W=0) As the temperature of substance passes through certain
thermal energy is required to raise the temperature of different substances The units in three different ways—through conduction, convection, and radiation
One thing drives heat transfers it is a difference in temperature CONDUCTION contact between substances Sight line - Can the objects “see” one another?
eventually reach room temperature The coffee and the mug are transferring heat to the surroundings This transfer of heat occurs from the hot coffee and hot
If you add energy as heat to a pot of water, the water's temperature starts to transferred through heat is shown on the So, each substance absorbs a different
If you have two objects or substances that are different temperatures, heat will always move OUT of the warmer object or substance, and INTO the cooler object or
