Answer the following question given this paragraph: Conduction is the transfer of thermal energy between particles of matter that are touching. Thermal conduction occurs when particles of warmer matter bump into particles of cooler matter and transfer some of their thermal energy to the cooler particles. Conduction is usually faster in certain solids and liquids than in gases. Materials that are good conductors of thermal energy are called thermal conductors . Metals are especially good thermal conductors because they have freely moving electrons that can transfer thermal energy quickly and easily. Q: What is the name for the transfer of thermal energy between particles of matter that are touching? Choices: - activation - induction - convection - conduction A:
(Answer)
conduction
Ques: Answer the following question given this paragraph: The model of an atom in Figure below has six energy levels. The level with the least energy is the one closest to the nucleus. As you go farther from the nucleus, the levels have more and more energy. Electrons can jump from one energy level to another. If an atom absorbs energy, some of its electrons can jump to a higher energy level. If electrons jump to a lower energy level, the atom emits, or gives off, energy. You can see an animation at this happening at the URL below. Q: In a model of an atom, the level with the least energy is the one closest to what? Choices: - center - surface - protons - nucleus A:
Ans: nucleus
(Q).
Answer the following question given this paragraph: The ability of a particular electrochemical cell to generate an electric current is called its electrical potential. Reduction potentials measure the tendency of a substance to be reduced in a redox reaction. Q: What do you call the ability of a particular electrochemical cell to generate an electric current? Choices: - momentum - kinetic energy - electromagnetism - electrical potential A:
(A).
electrical potential
Ques:Answer the following question given this paragraph: Solid carbon dioxide is also called dry ice. That's because when it gets warmer and changes state, it doesn't change to a liquid by melting. Instead, it changes directly to a gas without going through the liquid state. The process in which a solid changes directly to a gas is called sublimation . It occurs when energy is added to a solid such as dry ice. You can watch dry ice changing directly to a gas in the video at this URL: http://www. youtube. com/watch?v=J8mDGwf-5x0 . Q: What is another term for dry ice? Choices: - liquid nitrogen - ice crystals - carbonated ice - solid carbon dioxide A:

Ans:solid carbon dioxide
Ques:Answer the following question given this paragraph: ocean zone in the top 200 meters of water that receives enough sunlight for photosynthesis. Q: What is the top 200 meters of water in the ocean called? Choices: - over zone - thymic zone - organelle zone - photic zone A:

Ans:
photic zone
