- Rubbing your hands together warms them by converting work into thermal energy. If a woman rubs her hands back and forth for a total of 20 rubs, at a distance of 7.50 cm per rub, and with an average frictional force of 40.0 N, what is the temperature increase? The mass of tissues warmed is only 0.100 kg mostly in the palms and fingers. Your answer must have three significant figures and the temperature change in centigrade.arrow_forwardYou stand on top of a skyscraper and drop a rubber ball from a height of 163 m. As the ball bounces off the floor it converts some of its energy into thermal energy -- it becomes warmer. Eventually, it stops bouncing and it has converted all the energy it initially had into thermal energy. How much has its temperature risen? (The specific heat of rubber is 2005 J/(kg*K).)arrow_forwardHi! I have a question :) By adding 25 kJ to solid material A, 4.0 kg will melt. By adding 50 kJ to solid material B, 6.0 kg will melt. Solid material C requires 30 kJ to melt 3.0 kg. Which of these materials, if any, has the largest value for the heat of fusion? (A) A, (B) B, (C) C, (D) A=B, (E) None of the above.

At normal skin temperatures (37° C) the latent heat of vaporization of water is L, = 2.4 × 106 J/kg and density of water p = 998.2 kg/m³.arrow_forwardWhat is the role of “loose” electrons in heat conductors? (A) Loose electrons move quickly away from hot locations, making it impossible for energy to move and making the object a good insulator. (B) Loose electrons absorb energy, giving materials a high specific heat capacity. (C) Loose electrons vibrate and emit radiation that carries energy through the material at the speed of light. (D) Loose electrons transfer energy rapidly through a solid.arrow_forwardRubbing your hands together warms them by converting work into thermal energy.

If only some of the water ends up as steam, what percentage ends up as steam? Explain.arrow_forwardRadioactive decay of granite and other rocks in Earth's interior provides sufficient energy to keep the interior molten, to heat lava, and to provide warmth to natural hot springs. This is due to the average release of about 0.03 J per kilogram each year. Find an increase in temperature for a thermally insulated chunk of granite that takes about 12.6 million years to change temperature.

Use the equation Q=cmATQ=cmAT.)arrow_forwardWhen you turn your hot water on in the shower, it takes a bit for the water to get warm. Some of this is because the water in the pipe is cold but some of it is because the water from the hot water heater must heat the copper plumbing pipe itself. Copper has a specific heat of 0.39R. How much energy does it take to heat 2 kilograms of copper pipe from 70°F to 130°F? Report your answer in Joules. (Hint: Note that you'll need to convert kJ to J and F to K.)arrow_forward
