Starter 1) After playing outside on a cold day, Jaime went inside to wash his hands. Although the water was normal temperature, he noticed that it felt warmer than usual. What would explain this phenomenon? A His body had more kinetic energy than the water. B Heat flowed from a cooler substance to a warmer substance. C The water from the faucet had a higher temperature than his skin. D The thermal energy in the room was higher than the thermal energy outside. 2) The transfer of thermal energy from one object to another is known as A heat. B electricity. C magnetism. D temperature. 4) A science teacher filled one balloon with helium gas and a second balloon with carbon dioxide. The helium-filled balloon rose to the ceiling, and the balloon filled with carbon dioxide fell to the floor. Which statement is an inference based on this demonstration? A Each balloon behaved differently. B Helium gas has a lower density than air. C Carbon dioxide causes a balloon to expand. D Balloons can be filled with different gases. 3) Anita heats a beaker containing water. As the temperature of the water increases, which change to the water molecules occurs? A The molecules move at a faster rate. B The molecules become more massive. C The molecules expand and become wider. D The molecules separate into atoms of hydrogen
Starter 2) How does sound usually travel? A An object vibrates, and those vibrations travel through the air in one direction as transverse waves. B An object vibrates, and those vibrations carry air in one direction as longitudinal waves. C An object vibrates, and those vibrations carry air in all directions as transverse waves. D An object vibrates, and those vibrations travel through the air in all directions as longitudinal waves. 1) When a spoon hits a table, it makes a loud sound. When the spoon hits a soft cushion, it does not make a sound. What is the difference between the table and the cushion that accounts for the sound? A The table is more reactive than the cushion. B The table vibrates more than the cushion. C The table is more insulated than the cushion. D The table has more potential energy than the cushion. 4) Jake poured water into a pot. He put the pot on a stove and turned the stove on low. After a few minutes, the water in the pot began to boil. Which statement best describes why the water boiled? A The stove transferred light to the pot of water. B The stove transferred electricity to the pot of water. C The stove transferred heat energy to the pot of water. D The stove transferred mechanical energy to the pot of water. • 3) A block of ice is placed on a hot sidewalk. The ice melts because • A the energy from the ice flows to the sidewalk. • B the energy from the sidewalk flows to the ice. • C convection currents flow between the ice and the sidewalk. • D radiation flows between the ice and the sidewalk.
