How It Happens and the Different Types ©Copyright 2014 – all rights reserved

* What happens to the temperature if I add ice cubes to a glass of soda? * Write your answer down in your notes. Image Source: mbler_of_cola_with_ice.jpg

* How many of you wrote that the ice cubes make the soda cold? Image Source: cubes_openphoto.jpg/640px-Ice_cubes_openphoto.jpg

* What if I told you that ice cubes do not make soda cold? * In fact, it is the soda that warms up the ice cube! Image Source:

* When will the heat transfer between the soda and the ice cubes stop? Why? * Write your answer down in your notes. Image Source:

* How many of you wrote, “When the ice has finished melting?” * Please share your answers. Image Source:

* When the ice has finished melting, the temperature has increased. * When the ice was added to the soda, the temperature of the soda decreased. * The ice continued to melt until the soda and the ice reached the same temperature. * This is because heat transfer continues until both objects have reached the same temperature. * When the two objects have reached the same temperature, this is called Thermodynamic Equilibrium.

* In your notes, number a set of lines 1-5. * You will be shown a series of pictures. The pictures will show objects between which heat transfer will occur. * On your paper, draw an arrow showing which direction the heat will transfer in.

Cool Air Image Source: /?no_redirect Warm Skin Image Source: d_hair.jpg  Since the skin has a higher temperature than the air, the skin transfers heat to the air around it, making itself cooler.

When the two come into contact, heat transfers from the student to the chair. That’s why the chair feels cool.

* Step 1: Partner A looks at question one and shares the answer with partner B. * Step 2: Partner B either approves of the answer, or guides partner A to the correct answer. * Step 3: Once an answer is agreed upon, Partner A asks, "May I write it down?" * Step 4: Partner B either agrees or provides further coaching until a correct answer is agreed upon. * Step 5: Partner A picks up the writing utensil and writes down the answer. Then Partner A hands the writing utensil to Partner B, and the steps repeat. * If these instructions are not followed, you will complete the work by yourself.
