What is 218.00 'C in kelvins? A 491.15 K B 100.00 K C 473.15 K D 373.15 K The temperature difference of 1 K is the same as - A 1 0 c B 1 OF C 273.15 C D 273.15 OF 11 | THERMAL ENERGY, HEAT, AND WORK A glass of water has a temperature of 218 K. What state of matter is it in? Solid B Liquid 27.5 55 10 C Gas 20 50 D Plasma What is the difference between mal energy and internal energy? The thermal energy of the system is the average kinetic energy of the system's constituent particles due to their motion. The total internal energy of the system is the sum of the kinetic an tential energies of its constituent particles. B The thermal energy of the system is the average potential energy of the system's constituent particles due to their motion. The total internal energy of the system is the sum of kinetic and pot ntial energies of its constituent particles. C The thermal energy of the system is the average kinetic energy of the system's constituent particles due to their motion. The total internal energy of the system is the sum of the kinetic en constituent particles. The thermal energy of the system is the average potential energy of the systems' constituent particles due to their motion. The total internal energy of the system is the sum of the kinetic energies of its constituent particles. What is radiation? A It is the transfer of energy through emission and absorption of electromagnetic waves. It is the transfer of energy without any direct physical contact between any two substances. It is the transfer of energy through direct physical contact between any two substances. D It is the transfer of energy by means of the motion of fluids at different temperatures and with different densities.Essay Question: You must show your work to receive full credit! Q=mcAT Q = met Q = mLy A 334 kg sample of material is heated from 30.0 .C to 50 C. In the process, it absorbs 540 J of energy as heat. What is the specific heat of the sample? When 334 kg of a substance is completely melted at its melting point, 1700 J are absorbed. What is the heat of fusion of this substance? A hot piece of metal needs to be cooled. If you were to put the metal in ice or in cold water, such that the ice did not melt and the temperature of either changed by the same amount, which one would reduce the metal's temperature more? Why? A Water would reduce the metal's temperature more because water has a greater specific heat than ice. B Water would reduce the metal's temperature more because water has a smaller specific heat than ice. C Ice would reduce the metal's temperature more because ice has a smaller specific heat than water. Ice would reduce the metal's temperature more because ice has a greater specific heat than water. s vi the substance only What do latent heats, L and Lv, depend on? A Lf and Ly depend on the forces between the particles in the substance. B LF and Ly depend on the mass of the substance. C Lf and Lv depend on the volume of the substance. D) Lf and Ly depend on the temperature of the substance. How much energy is required to melt 218.00 g of a block of aluminum that is at its melting point?
