During the winter, after a hot bath, is it more efficient to drain the tub immediately or let it sit? Explain. page 3 WS PS U2

4 Problem Solving. Answer the following questions. Show work or receive no credit. Use proper units. 30. If you warm a 35-kg pile of sand from 300 K to 350 K, and the specific heat of sand is 664 [J/(kg K)], what is the change in thermal energy? 31. If you warm a 35-kg substance from 300 K to 350 K and find the thermal energy change is J, what is the specific heat in J/(kg K)? 32. If you cool the same pile of sand from problem #9 from a temperature of 350 K to 300 K, will you have the same thermal change? Explain showing work. True/False. Determine whether the italicized and underlined term makes each statement true or false. If the statement is true, write True in the blank. If the statement is false, write in the blank the term that makes the statement true. Not following these directions will result in no credit Particles that make up matter are in constant motion. The faster particles move the less kinetic energy they have. Temperature is the measure of the average kinetic energy of the particles in an object. When temperature increases, the kinetic energy of the particles decreases. The thermal energy of an object is the total energy of the particles in a material. A 5-kg chunk of aluminum and a 5-kg block of silver that are at the same temperature have the same thermal energy. Heat flows from a higher temperature to a lower temperature. Heat is measured in newtons. Different materials need the same amounts of heat to have similar changes in temperature. page 4 WS PS U2

5 The amount of energy it takes to raise the temperature of 1 kg of a material 1 kelvin is the specific heat of the material. Water has a relatively low specific heat. Materials with a high specific heat can absorb a lot of energy and show little change in temperature. Section 6.2 Crossword Puzzle. Complete the crossword puzzle with the words that best fit the descriptions. Across: 2. Transfer of energy in the form of electromagnetic waves 7. A measure of the average kinetic energy of all the particles in an object Down: 1.

(A) solids and liquids (C) solids (B) solids and gases (D) liquids and gases Of the following, the best insulator would be. (A) silver (B) copper (C) air (D) iron Fluids expand as the temperature of the fluid. (A) increases (B) decreases (C) stays the same The density of a fluids increases as the fluid. (A) expands (B) contracts (C) stays the same Determine whether the italicized and underlined term makes each statement true or false. If the statement is true, write True in the blank. If the statement is false, write in the blank the term that makes the statement true. Not following these directions will result in no credit Materials that are poor conductors are poor insulators. The transfer of energy through matter by direct contact of its particles is convection. The transfer of energy in the form of invisible waves is conduction. Solids usually conduct heat better than liquids and gases. Air is a poor heat conductor. Energy is usually transferred in fluids by radiation. As water is heated, it expands, becomes less dense, and rises. Dark-colored materials absorb less radiant energy than light-colored materials. Only radiant energy that is reflected is changed to thermal energy. page 6 WS PS U2

Determine whether the italicized and underlined term makes each statement true or false. If the statement is true, write True in the blank. If the statement is false, write in the blank the term that makes the statement true. Not following these directions will result in no credit Waves transfer matter as they travel. A wave will travel only as long as it has energy to carry. Anything that moves up and down or back and forth in a rhythmic way is vibrating. All waves need a medium in order to travel. Transverse and congressional waves are the two types of mechanical waves. In a compressional wave, the matter in the medium moves back and forth at right angles to the direction that the wave travels. In a transverse wave, the matter in the medium moves back and forth in the same direction that the wave travels. In a transverse wave, the peak of the wave is the crest and the lowest spot is the trough. The refraction of a wave is how many wavelengths pass a fixed point each second. The speed of a wave is determined by multiplying the wavelength by the frequency. In a compressional wave, the denser the medium is at the compressions, the smaller its amplitude. In a transverse wave, the higher the amplitude, the more energy it carries. page 12 WS PS U2
