Instructions: Find Chapter M section 1 on page 177 in the magenta Science Explorer textbook. Answer the following questions as you read.
1- Energy of motion is ______energy, so since all particles of matter are ______, they all have kinetic energy.
2- What is temperature?
3- Make an inference, which has greater average kinetic energy, ice cream or cold milk? Why?
5- Why does the liquid inside a thermometer rise when it contacts warm substances?

12- Make an inference, which has greater thermal energy, a large ice burg or a burning match?
13- True or FalseAn object has heat if it feels warm to the touch.
14- Explain why an ice cube will melt in your hand.
15- What is specific heat?
16- Analyze the graph to the right. About how much heat is required to raise 1 Kg of water from 300oK to 301oK?
17- According to the graph, which will feel “hotter”, sand at the beach or a quarter (which contains iron) left on the same beach?
18- What is the equation to calculate the change in energy of a material?
19- Locate your yellow reference sheet on page 2 in your notebook and find the equation labeled as “Heat transferred” on the upper right side. Write that equation below.
20- What is the relationship between “change in energy” and “heat transferred” in the two equations?
21- What does the little triangle in front of the T mean?
22- If heat is a form of energy, what units do we measure it in? (same as all energy units)
22- How much energy is required to raise the temperature of 5 Kg of water by 10 Kelvins? (show your work – 2 pts)
24- How much more energy is required to raise the temperature of 1 Kg of iron by 1 K than to raise the temperature of 1 Kg of copper by 1K. Use the table on p. 181. Show your work for both substances. (4 pts)
