PHYS 205 Winter 2019 Lab 1 Homework NAME 6. Two identical glasses contain equal samples of water, however the water in glass A has twice the thermal energy as the water in glass B. Compare the temperature of the water in Glass A to that of Glass B, explain your reasoning. Glass A Glass B 7. Two identical glasses contain different amounts of water. Glass A contains 500 mL of water and Glass B...
1) The amount of energy transferred between two objects is considered a. heat b. specific heat c. thermal energy d. temperature 2) Temperature of land rises more quickly than that of the sea because ? a. soil is solid whereas water is liquid b. specific heat of soil is higher c. specific heat of soul is lower than that of water
Two objects, with different sizes, masses, and temperatures, are placed in thermal contact. Energy travels (a) from the larger object to the smaller object (b) from the object with more mass to the one with less (c) from the object at higher temperature to the object at lower temperature.
Problem 2 Suppose that the heat capacities CA and CB of two objects A and B are measured at constant pressure and they are found to be temperature-independent. Initially, TB > TA. Suppose the two objects are brought into thermal contact but are isolated from the surroundings. What is the equilibrium temperature of the combined objects?
A and B are two unknown elemental gases in two separate containers. A has a higher molar mass than B . Which of the following statements is true? a) The average kinetic energy of A is greater than B b) If A and B are at the same temperature, urms,A = urms,B c) If A and B are at the same temperature, urms,A > urms,B d) If A and B are at the same temperature, the average kinetic energy of...
What happens when two objects are in thermal equilibrium? A. The two objects reach the average of their two temperatures. B. The two objects contain the same number of atoms but have different temperatures. C. The temperatures of the two objects have stopped changing even though they are at different temperatures. D. Heat no longer flows between the two objects when they are both at the same temperature.
When two objects are in thermal contact heat energy is transferred from the hot to the cold object until the temperature of both becomes equal (i.e., the objects are in thermal equilibrium). Suppose you pour 20-gram milk at 200C into a cup of 80-gram tea at 920C. Assume the specific heat of tea is 4.2 J/gram.0K and that of milk is 3.9 J/gram.0K Assuming no heat is lost into the surrounding air what is the temperature of the tea and...
Two identical objects are in thermal contact. One is at a high temperature (T-hot) and the other is at a cool temperature (T-cool). Assume that this system is isolated, i.e. there is no interaction with the surroundings. Using the thermodynamic definition of entropy, explain why heat always flows from T-hot to T-cool, and never the other way around.
Two substances, A and B, have the same mass. Substance A is at a higher temperature than B, and heat transfers between them until equilibrium is reached. The decrease in the temperature of A is less than the increase in temperature of B. Which substance has the larger specific heat?
Two objects of different material have the same mass and temperature. When adding them equal amount of heat, the final temperature of each one can be different since they have different? Specific heat Density Expansion Coefficient Thermal conductivity Volume
