Why would sand heat and cool faster than water?@. Sand has a lower specific heat capacity than water.a. Water has a higher specific heat capacity than sand.b. Water has a lower specific heat capacity than sand.c. Sand has a higher specific heat capacity than water.*d. Sand has a lower specific heat capacity than water.3. Consider heating a beaker of water. If you want to add 5 calories of heat to 1 gram of water, how will the temperature change?@ Heat calories are proportional to the temperature. So, if you add 5 calories of heat to 1 gram of water, you’ll raise the temperature of the glass by 5?C. *a. It will increase to 5?C. b. It will decrease to 5?C. c. It will increase to 1?C. d. It will increase to 1?C. **This is also a quiz question. 4. What happens to energy when you hold a cube of ice in your hand?@ When you hold the ice, thermal energy flows from you hand to the ice. a. Cold flows from ice to your hand.b. Simultaneously, cold flows from the ice to your hand, and eat flows from your hand to the ice.*c. Thermal energy flows from your hand to the iced. None of the above.5. When a liquid or gas is heated, it expands and becomes less dense. The less dense material then rises, while cooler, more dense material sinks to take its place. This is known as:@This is the definition of convection.a. Conductionb. Radiationc. Condensation*d. Convection6. Let’s say you are drinking a hot cup of tea. The cup is full and acts as an insulator for the tea. In addition, you are using a spoon to stir your sugar. While in the glass, the spoon is acting as what?@ Conduction occurs when two substances are in contact with each other, and the heat energy is transferred directly. The mechanism which this is occurs is a conductor. The spoon is acting as a conductor from the hot tea to your hand.*a. Conductorb. Radiatorc. Condensord. Convector7. On a cold winter day, someone knocks on the door and you open it to see who it is. When the door opens, the house becomes cooler. How does this heat transfer occur?@ Heat is transferred from hotter materials to cooler materials. *a. The warmer air from inside is transferred outside.b. The cooler air from outside is transferred inside.c. The warmer air from inside is not affected by the outside. 8. What is defined as “the change of state of matter directly from solid to gas, bypassing the liquid phase?@ This is defined as sublimation.a. Subluxation*b. Sublimationc. Suxtationd. Sedation9. When an object is heated, how will its volume change?@ When heated, objects expanda. It will dissolveb. It will contractc. It will explode*d. It will expand10. Which of the following are changes in states of matter? Select all that apply. @ These are all changes in states of matter.*a. Melting*b. Vaporization*c. Condensation*d. Sublimation. ................
