What’s the difference between kinetic and potential energy? Energy transformation What’s the difference between kinetic and potential energy? Give a real-life example of each.

WATER FLOWING IN A RIVER Kinetic Energy energy in motion EXAMPLES SKIING DOWNHILL WATER FLOWING IN A RIVER EROSION

Potential Energy stored energy EXAMPLES AT THE TOP OF A SKI SLOPE WATER BEHIND A DAM DEPOSITION

What is the relationship between Potential Energy and height? Veruckt!

As Height of an object INCREASES, The potential energy INCREASES Direct relationship

Measuring temperature

Temperature Conversions Fill in the chart below using Page 13 Earth Science Reference Tables. Fahrenheit (°F) Celsius (°C) Kelvin (K) 30 330 -1 272 86 303 135 57

Describe the word TEMPERATURE in relation to molecular motion. Temperature Conversion Describe the word TEMPERATURE in relation to molecular motion. Cold Hot

At absolute zero, all molecular motion stops. 0K -273°C -459°F Temperature Conversion What happens to molecular motion at absolute zero? What temperature is this in all temperature scales? At absolute zero, all molecular motion stops. 0K -273°C -459°F

???Why do we here on Long Island not have many snow days??? Something to think about….. ???Why do we here on Long Island not have many snow days???

the amount of energy required to raise the temperature of Specific Heat the amount of energy required to raise the temperature of 1 gram of a substance 1°C Please go to Page 1 of the Earth Science Reference Tables.

Why does water heat up and cool down more slowly than land? Specific Heat Why does water heat up and cool down more slowly than land? Water has a higher specific heat

the lead because it has a lower specific heat If you heated equal masses of basalt and lead, which one would record a faster increase in temperature? Explain how you know. the lead because it has a lower specific heat

Which Earth material has the greatest specific heat? liquid water

How does the high specific heat of water affect us here on Long Island every day??? Let’s find out…….. Absorption and Radiation Lab

Where is the air warmer? cooler? Draw Draw the convective cell

Where is the air warmer? Cooler?

How does water’s high specific heat affect our climate? Patchogue, NY Lincoln NE

January 39⁰ 35⁰ July 83⁰ 89⁰ Avg. Temperature Patchogue, NY Lincoln, NE January 39⁰ 35⁰ July 83⁰ 89⁰

high specific heat Long Island has cooler summers and warmer winters than Nebraska because of water’s _____ ______ ________! high specific heat

Something to think about….. World climate data

Properties of Water

required to cause water to Something to think about….. How much energy is required to cause water to boil????

PROPERTIES OF WATER Look on page 1 of your ESRT’s

2260 2260 334 334 How many Joules are gained or lost by water for each of the following processes? Process Joules Gained Joules Lost Condensation Evaporation Melting Solidification 2260 2260 334 334

Heating Curve for Water Draw the graph of water heating. Label the following terms in their correct places: condensation, vaporization, solidification, melting. Heat lost vaporization (+2260 J) gas 100 condensation ( -2260 J) melting (+334 J) liquid Temperature (oC) solidification (-334 J) solid Heat added

Phase Changes At certain temperatures, materials will change phase Solid, liquid, or gas As the material changes phase, the temperature will REMAIN CONSTANT until … the entire substance has changed phase. Known as Latent heat

a burn from boiling water. Something to think about….. A burn from steam can be more severe than a burn from boiling water. Why?? video
