A heat pump that is used to heat a house has a COP of 2.5. That is, the heat pump delivers 2.5 kWh of energy to the house for each 1 kWh of electricity it consumes. Is this a violation of the first law of thermodynamics? Explain.
The 2nd Law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system.True or False
Consider the human body performing a strenuous exercise, such as lifting weights or riding a bicycle. Work is being done by the body, and energy is leaving by conduction from the skin into the surrounding air. According to the first law of thermodynamics, the temperature of the body should be steadily decreasing during the exercise. That isn’t what happens, however. Is the first law invalid for this situation? Explain.

- When a gas undergoes an adiabatic expansion, which of the following statements is true? (a) The temperature of the gas does not change. (b) No work is done by the gas. (c) No energy is transferred to the gas by heat. (d) The internal energy of the gas does not change. (e) The pressure increases.arrow_forwardConsider the following statements about the Zero Law of Thermodynamics: 1. Two bodies are in thermal equilibrium if they both have the same temperature reading, even if they are not in contact. 2. This law states that, if two systems are in thermal equilibrium with a third system, they cannot be in thermal equilibrium with each other. 3. This law states that, when two systems are in contact, heat will be transferred from the colder system to the hotter one. 4. When two bodies in thermal equilibrium are in contact, there is no net heat transfer between them.

(b) in every physical process, the total amount of energy must remain unchanged. (c) non-thermal forms of energy cannot be entirely converted into thermal forms of energy. (d) in physical process in which heat is produced, the total amount of energy is reduced by an amount equal to amount of heat produced.

- Problem 1: Which of the following would violate the Second Law of Thermodynamics? Choose one that applies. OA 130 °F cup of hot coffee is placed on the table in a 75 °F room. Without any work being exerted and with no chemical reactions the cup of coffee heats up. O1,000 kJ of energy are available from a hot thermal reservoir. A heat engine converts 600 kJ to work and rejects 500 kJ to a lower temperature reservoir. A swinging pendulum gets lower and lower as friction takes energy out of the system. As a block slides down a rough incline heat is generated from friction. O Work is done and heat is made to go from a lower temperature reservoir to a higher temperature reservoir. O An inventor builds a device that is able to convert a specific amount of heat entirely to work in a thermodynamic cycle.arrow_forwardThe internal energy of a gaseous system is initially 63 J. A total of 71 J of energy is added to the system as heat while the system does 59 J of work. The system does not undergo a change of state. What is the system’s final internal energy? Does the system’s temperature increase, decrease, or stay unchanged? A student in a chemistry lab class prepares to do a test of Boyles Law. The student presses down rapidly on the piston of a gas filled syringe and causes adiabatic compression of the gas. The student did 75 J of work on the gas. What was the change in internal energy of the gas? Did the temperature of the gas increase, decrease, or not change?arrow_forwardYou observe a grasshopper eating a blade of grass. You know that each blade of grass contains 100 units of energy. You then measure the energy level of the grasshopper using a fancy device. You notice that the grasshopper only has 20 units of Energy after eating two blades of grass. Based on what you have learned about thermodynamics, where did the rest of the energy go?arrow_forward
- You are watching a new bridge being built near your house. You notice during the construction that two concrete spans of the bridge of total length L, = 280 m are placed end to end so that no room is allowed for expansion (figure (a)). In the opening storyline for the thermodynamics chapter, we talked about buckling sidevalks. The same thing will happen with spans on bridges if allowance is not made for expansion (figure (b)). You vwant to warn the construction crew about this dangerous situation, so you calculate the height y to which the spans will rise when they buckle in response to a temperature increase of AT = 21.0°c. T+ AT y =arrow_forwardThe first law of thermodynamics relates the heat transfer into or out of a system to the change of internal and the work done on the system. How much heat, in joules, is transferred into a system when its internal energy decreases by 165 J while it was performing 27.5 J of work?arrow_forwardA typical weather balloon is made of a thin latex envelope that takes very little force to stretch, so the pressure inside the balloon is approximately equal to atmospheric pressure. Suppose a weather balloon filled with 180 mol of helium is waiting for launch on a cold morning at a high-altitude station. The balloon warms in the sun, which raises the temperature of the gas from0°C to 30°C. As the balloon expands, how much work is done by the expanding gas?arrow_forward
