1 HEAT AND HEAT TRANSFER
2 What is the difference between temperature and heat? Temperature is a measure of the average kinetic energy of atoms. This means: the higher the temperature, the faster the atoms move the lower the temperature, the slower the atoms move Less Heat Thermometers are used to measure temperature More Heat
3 If energy is added to atoms, they move faster. The faster they move, the further apart they move. This spreading out of atoms happens in solids, liquids and gases. The term for this type of expansion is called THERMAL EXPANSION. Thermal expansion is why running a tight jar lid under warm water loosens the lid. *pg 154
4 THERMAL EXPANSION The spreading of particles or increased volume when an object is heated is known as THERMAL EXPANSION
5 WHAT IS HEAT? Heat=transfer of energy between objects that are different temperatures (atoms rubbing together). pg. 155
6 Another word for heat is THERMAL ENERGY. Hot objects contain more thermal energy than cold objects Heat Transfer= Heat (thermal energy) is transferred from warmer objects to cooler objects.
7 How cold is cold? There is no such thing as coldness. What we call cold is really absence of heat or slow atoms. Even when it is 15 degrees outside, that is 15 degrees of HEAT, NOT 15 degrees of COLD.
8 Can a balanced temperature ever be reached? YES, IT S CALLED THERMAL EQUILIBRIUM No energy transfer occurs Pg. 156
9 THERMAL EQUILIBRIUM The point at which two objects reach the same temperature.
10 HEAT IS TRANSFERRED IN THREE WAYS BY CONDUCTION CONVECTION RADIATION
11 CONDUCTION ØTransfer of heat from one substance to another by direct contact. ØHappens within and between objects that touch each other ØBest conduction happens in solids ØExamples: Sauce pan on a stove top, metal spoon in a bowl of soup, ice melting in a warm hand, hot shower, walking on hot coals
12 Objects that heat up easily are called CONDUCTORS. Metals are the best conductors Metal objects feel cold because they conduct heat AWAY from your hand Objects that DO NOT heat up easily are called INSULATORS. Things like glass,wood, plastic and rubber are good insulators
13 Which parts of the pan are conductors and which are insulators?
14 CONVECTION Transfer of heat in liquids and gases ONLY Heat moves up and down in a circular motion called a CONVECTION CURRENT Heated liquids and gases are less dense & rise carrying heat with them Examples: hang gliders, soaring birds, home furnace heating & circulating air
15 Convection currents cause the Earth s tectonic plates to move about.
16 RADIATION v transfer of heat through empty space in form of infrared radiation waves (what we think of as heat waves) vexamples: blacktop heats up on a sunny day, hot sand on a beach, electric heaters.
17 Explain how each of these uses radiant heat.
18 BELLRINGER 1. Describe how heat is created. 2. Give 2 examples of thermal expansion. 3. What is the difference between hot and cold? 4. How does heat move? 5. Describe all the heat transfers in the diagram.
19 How does heat affect matter? Physically: heat changes the state in which matter exists i.e. melting, freezing, evaporating, condensing
20 Chemically: for chemical reactions to occur, chemical bonds must be broken and new compounds formed. Requires energy to be absorbed or released
21 HEAT ON EARTH WATER AND LAND Heat comes to the Earth from the Sun by radiation. ØLight passes through the atmosphere ØLand and water absorb the light and become warm ØLand and water reflect infrared waves (also radiant energy) back into space BUT NOT ALL OF IT. ØWater vapor, CO2 and other gases block these waves and the Earth gets hotter. Called the Greenhouse Effect
22 HEAT ON EARTH
23 HEAT ON EARTH THE ATMOSPHERE Because of the Earth s curved shape, its surface and atmosphere are NOT heated evenly. ØIf Earth was flat, all surfaces would be heated evenly ØConvection causes air to move between warm regions and cold ones. ØThis redistributes the sun s energy all over the Earth. ØWind is caused from these convection patterns
24 HEAT ON EARTH THE ATMOSPHERE
25 HEAT ON EARTH THE ATMOSPHERE
26 HEAT ON EARTH THE OCEAN vone interesting property of water is that it can absorb large amounts of heat. vsince most of Earth s surface is covered by water, it is able to store much more heat than land. vthe climate of the entire Earth is much more moderate than it would be if the oceans did not exist. vthe oceans act like vast heat storage tanks.
27 The convection patterns in the atmosphere, the heat stored in the oceans and the evaporation caused by the sun s rays striking the Earth all cause the WEATHER. HEAT ON EARTH THE WEATHER
28 KATRINA APPROACHES HEAT ON EARTH THE WEATHER
29 HEAT ON EARTH UNDERGROUND Interior heat left over from when the Earth was formed 4.5 billion years ago. Convection currents carry heat to the crust but extremely slowly. Rock is a poor conductor. Evidence of interior heat: volcanoes, geysers, bubbling hot springs.
