A copper rod of 30 kg initially at the temperature of 300 °C needs to be immersed and fitted tightly into a ABA alloy ring with inner diameter 30.0015 mm found in tank of 100 liters water of 25 °C. (i) Determine the diameter copper when it is 300 °C. (ii) In your opinion, does the copper rod will still fit tightly into the ABA alloy ring inner diameter 30.0015 in the ambient air condition of 25 °C. Provide your answer in 4 decimal places.

Citrus fruits are very susceptible to cold weather as extended exposure to subfreezingtemperatures can destroy them. Consider an 8-cm-diameter orange, that is initially at 10°C. A cold front moves inand the temperature drops to -2°C, with a heat transfer coefficient of 25 W/m2K. Using the properties of water for theorange, and given the ambient conditions remain constant for 7 hours, to what depth r will the orange freeze, if itdoes at all. Ignore any latent heat of solidification effects as the orange freezes.
