1. SPECIFIC HEAT

2. AIM: DO NOW: HW:

3. AIM: Could you be more specific. DO NOW: HEY……
AIM: Could you be more specific??? DO NOW: HEY……. IT’S JUNE 21, BUT THE WATER IS COLD!!!!!!! WHAT GIVES????? HW: 1. WIZARD QUIZ DUE FRIDAY 2. Lab # 21 due TUESDAY 1/8

4. What is Specific Heat?
How fast a substance heats up and cools down
The JOULES (NRG) required to heat 1 gram of a substance by 1o Celsius

5. AIM: WHAT ARE THE TYPES OF HEAT. DO NOW: 1. TAKE OUT MIDTERM REVIEW
AIM: WHAT ARE THE TYPES OF HEAT? DO NOW: 1. TAKE OUT MIDTERM REVIEW. IF IT IS NOT FINISHED IT IS A DOT FOR EVERY DAY IT IS INCOMPLETE. DO NOT HAND IT IN UNLESS IT IS COMPLETE. HW: 1. INSOLATION WIZARD DUE TOMORROW AT 8AM 2. LAB # 21 DUE TUESDAY 1/8

10. What do the numbers tell us?
The higher the number, the longer it takes to heat up and cool down.
The lower the number, the faster it will heat up and cool down.

11. Specific Heats of Common Materials
Which substance has the highest specific heat?
Which substance has the lowest?
Which one will heat up and cool down fastest?

12. So, how does this relate to the Earth?
The crust of our planet is made up of 2 kinds of rock: Basalt and Granite.
These rocks have low specific heat, and therefore heat up fast, and cool off fast.

13. What does the water feel like during the early day?
Water heats up very slowly due to its HIGH specific heat.
This is why the sand feels so hot in the day time, while the water still feels cold.
What will the water feel like later during the day??
