How ‘Heat’ Moves  Define “ Heat ”: Heat is the movement of thermal energy from a substance at a higher temperature to another substance at a lower temperature.

Heat is Transferred 3 Ways

CONVECTION: THE TRANSFER OF THERMAL ENERGY BY THE MOVEMENT OF THE PARTICLES FROM ONE PART OF A MATERIAL TO ANOTHER; TRANSFER OF THERMAL ENERGY IN A FLUID.

Heat Transfer. Energy transfer from a HOTTER object to a COOLER one.

 Thermal conductor – a material through which thermal energy flows easily  EX: metals  Thermal Insulator – a material through which thermal energy.

Radiation – the transfer of energy through space. Heat transfer by radiation takes place with no direct contact between a heat source and an object. Example.

Transfer of Energy Energy Transfer Energy is transferred from hotter object to colder object Examples? –Cooking pasta –Making ice –Making popcorn –Roasting.

Heat Transfer. Heat is the transfer of thermal energy between substances that are at different temperatures.

How many ways are there to transfer heat? How can thermal energy (heat) be transferred?

METHODS OF HEAT TRANSFER.

What processes heat the atmosphere?

Conduction The transfer of energy as heat between particles collide within a substance or between two objects in contact Two objects of unequal temperature.

 Particles are always moving and always have energy.  When an object is hot… the molecules are moving_____________.  When an object is cold…the molecules.

Chapter 7 Heat Transfer. Convection Currents and the Mantle What will we learn: 1.How is heat transferred? 2.What causes convection currents?

Types of HEAT Energy Transfers CONDUCTION Objects are in direct contact. Heat energy transfers when particles collide or objects in contact are TOUCHING.

Energy Transfer Methods of energy Transfer Three ways energy is transferred: 1. Conduction- occurs between objects in direct contact. a. Objects.

Standards 3: Thermal Energy How Heat Moves  How heat energy transfers through solid.  By direct contact from HOT objects to COLD objects.

Thermal energy, temperature & heat Different objects at the same temperature can have different energies. You may be used to thinking about thermal energy.

Transfer of Thermal Energy

I. WHAT IS TEMPERATURE? We don’t use the terms hot and cold often in science because they are relative terms: They could mean different things depending.
