The handle of a spoon in a bowl of hot soup becomes warm due to heat transfer by the process of Conduction

When you rub a piece of sandpaper against a wooden board, ___________ causes some of the kinetic energy to be transformed into thermal energy. Friction

True or False A student lists three temperature measurements: 100°F, 100°C, and 100 K. Of the three measurements, 100 K is the highest temperature. False . . .100° C

True or False If heat is removed from a system, the temperatures of substances in the system increase. False . . . . Decrease

True or False Chemical energy is potential energy stored in bonds between atoms.

True or False The more particles a substance has at a given temperature, the more thermal energy it has. True

True or False If heat is transferred from Object A to Object B, the temperature of Object B decreases. False . . . Increases

Beaker C has the most thermal energy because it has the highest temperature and as much water as any other beaker.

Heat will be transferred from the warm air to the cold soda. Short Answer Suppose you leave a glass of ice-cold soda on a table in a warm room. In what direction(s) will heat be transferred in this system? When does the heat transfer stop? Heat will be transferred from the warm air to the cold soda. Heat transfer stops when the air and soda all have the same temperature.

Short Answer Identify three temperature scales that people use. The three temperature scales are Fahrenheit, Celsius, and Kelvin.

Short Answer Describe the energy transfer that takes place in a battery powered flashlight. The chemical energy in the battery is transformed into electrical energy that flows through the wires and finally transforms into electrical and heat energy in the light bulb.

Short Answer Describe the energy transformations in each picture . A music player changes chemical energy (battery) into electrical energy and then into sound energy

Short Answer Describe the energy transformations in each picture . A hot plate changes electrical energy into thermal energy. Some electrical energy also changes into EM energy (light)

Short Answer Describe the energy transformations in each picture . Solar panels change EM energy from the sun into electrical energy

Short Answer Describe the energy transformations in each picture . A fan changes electrical energy into mechanical energy.
