Chapter 7 & 8 TEST
Give two examples of ways in which animals keep themselves warm or cool ?
many birds fly south when it gets cold in northern regions snakes and lizards basks in the sun to keep their bodies warm.
an example on how keep themselves cold in the summer in the summer in the summer building can be cooled by fans window air conditioner or central air conditioners air conditioners use much more energy than fans do keeping interiors comfortable all year long is important to consider in the constructions and maintenance of all buildings
The particle theory matter are theory that explains what matters made of and how it behaves all matters made out of tiny particles
particles have spaces between them
particles moving all the time
particles move faster when they are heated
and particles attract to each other
HEAT when an object it's particles move faster when an object is cold it's particles more slow When an object comes into contact with a cold object the faster moving particles of a warm object bumps into the slower moving particles of the cold object as a result energy is transferred this causes particles of the cold object to speed up and the particles of the warm object to slow down
heat the transfer of energy from the particles of a warmer object to the particles of a cooler object
thermal expansion and increase in the volume of substance caused by the heating
thermal contraction a decrease in the volume of substance caused by the cooling
conduction the transfer of thermal energy through a substance or between substances and contact by the collusion of particles
geothermal energy energy contained below or the surface
metamorphic rock rock that is formed when heat and pressure change existing rock
indigenous rock rock form from magma that is cooled and solidified
convection the transfer of thermal energy from one part of a fluid to another by circulating current of faster moving and slower moving particles
when the sun goes down in the evening the land cools more quickly than the water The warm water heats the air above it making the air less dense The cool air air over the land moves down and out towards the water This pushes the less dance lighter air over the water Higher into the atmosphere a land breeze found moors from the land towards the water
the temperature of the Earth Mental increases as you go deeper So the top of the mental is cooler than the bottom. Over millions of years cooler mental rock sinks as warmer mental rock rises closer to the Earth's crust This creates very slow convection currents figure 5 these convection currents transfer energy and make cause whole chronic eruptions
radiant rich energy energy that travels in the form of electromagic waves through empty space includes visible lights on violence race and inferred race
radiation the transfer of radiant energy by means electromagnetic waves
