**Graph Title: Effect of Acclimation Temperature on Metabolic Rate in Lizards** **Y-Axis: Rate of O₂ consumption (mL O₂/h) on log scale** - The Y-axis measures the rate of oxygen consumption, represented on a logarithmic scale from 0.8 to 8.0 mL O₂/h. **X-Axis: Body temperature (°C)** - The X-axis indicates the body temperature, ranging from 16°C to 33°C. **Data Series:** - **16°C-acclimated (Blue Line):** Represents lizards acclimated to a cooler ambient temperature. - Data Points: - ~1.0 mL O₂/h at 16°C - ~2.5 mL O₂/h at 28°C - ~6.0 mL O₂/h at 33°C - **33°C-acclimated (Red Line):** Represents lizards acclimated to a warmer ambient temperature. - Data Points: - ~0.9 mL O₂/h at 16°C - ~2.0 mL O₂/h at 28°C - ~4.5 mL O₂/h at 33°C **Key Observations:** - Lizards acclimated to a cooler ambient temperature exhibit a higher average metabolic rate at any given body temperature compared to those acclimated to a warmer ambient temperature. **Text Boxes:** - **Top Box:** "Lizards acclimated to the cooler ambient temperature have a higher average metabolic rate at any given body temperature..." - **Bottom Box:** "...than those acclimated to the warmer ambient temperature." **Illustration:** - An image of a lizard is present, emphasizing the subject of the study. **Background:** - The graph has a light green background, aiding in the differentiation of the data points and lines.

Your house has an electric water heater. Several friends are visiting you over the weekend and they are taking consecutive showers. Assume that at the maximum heating level, the heater uses 50 kW of electricity. The water use rate is a continuous 4 gallons per minute with the new water saving showerhead you recently installed. Your very old showerhead had used 7 gallons per minute. You replaced the showerhead because you learned that heating water was the second highest energy use in your home. By slowing the flow of water through the heater, the water temperature should increase to a higher temperature. (a) What is the change in temperature (T) for the old showerhead? (b) What is the change in temperature (T) for the new showerhead? Assume the system is at steady sate, and all of the 50 kW energy used is heating the water.

Conduction Heat Transfer X material (a) material (b) . both (a) and (b) have the same thermal conductivity the temperature distribution is independent of thermal conductivity it's not that simple 9. Fin efficiency is defined as: • tanh (mL) (hP/k Ac)1/2 (heat transfer with fin) / (heat transfer without fin) (actual heat transfer through fin) / (heat transfer assuming all fin is at T = Tb) (Tx=L-Tf)/(Tb-Tf) 10. For an infinite fin, the temperature distribution is given by: (T-Tf)/(Tb-Tf)= e-mx. The heat flow through the fin is therefore given by: k (Tb-Tf)/L ● zero, because the fin is infinite ● infinite because the fin is infinite ● (Tb-Tf) (hP/k Ac)1/2 ● (Tb – Tf) (h P / k Ac)1/2 tanh (mL) 11. The Biot number, Bi, is defined as: • Bi=hk/L • Bi=hL/k • Bi= k/LH • Bi=qL/k • Bi=p UL/k 12. For a plate of length L, thickness, t, and width, W, subjected to convection on the two faces of area L x W. What is the correct length scale for use in the Biot number? . L ● W ● t • t/2 • L/2 13. If Bi…

An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J).  It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).

A 370-g sample of an unknown (nongaseous) material experiences a 24.0°C increase in temperature after absorbing 1.24 x 103) of energy. (a) What is the specific heat of this material? 3400 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. J/(kg. °C)
