Two objects, with different sizes, masses, and temperatures, are placed in thermal contact. Energy travels 1 2 3 33% 33% 33% 1 2 3 4 5 1. from the larger object to the smaller object 2. from the object with more mass to the one with less 3. from the object at higher temperature to the object at lower temperature

The direction of the transfer of energy depends only on temperature and not on the size of the object or on which object has more mass.

Consider the following pairs of materials. Which pair represents two materials, one of which is twice as hot as the other? 1 2 3 4 25% 25% 25% 25% 1 2 3 4 5 1. boiling water at 100°C, a glass of water at 50°C 2. boiling water at 100°C, frozen methane at -50°C 3. an ice cube at -20°C, flames from a circus fire- eater at 233°C 4. No pair represents materials one of which is twice as hot as the other
