Question

Question 1 You combine a solid unknown salt-like substance to water in a beaker. You pick up the beaker and observe that the beaker has gotten very cold to the touch. The reaction is ( endothermic ). If we define the unknown substance and the water as the system and the surroundings as the beaker and your hand, then heat flows Question 2 is the kinetic energy associated with the random motion of atoms. is the quantitative measure of hot and cold. A) is the transfer of thermal energy between two objects. Question 3 A 15.2 g piece of an unknown metal loses 351 J of energy when it cools from 95.0°c to 35.0 °C. What is the specific heat of the metal? Question 4 Use this Specific Heats of Common Substances to identify the possible identity of the metal from the previous question.

Answer 1

0 in endothermic reach the system from the heat flows from the heat ix absorbed by surrounding ie the surrounding to system. @ associated The -mal energy is the kinetic the random motion of energy atoms with quantitative measure of Temperature is the hot & cold. Conduction is the transfer of thermal energy between two objects. | ③ heat capacity - mars (To-To -351) 15.29 (35-95)°C = + 0.384 I T-ve sign is due to I the loss of energy. - ☺ According Unknown it seems the value of specific heat of the substance że .ogg 0.384 I that this is copper NIB. The specific this is a heat of a substance is constant and characenistic value. You can see
