Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

When determining the specific heat of a metal specimen, what would happen to your experimental results if too much cold water were placed in the inner calorimeter cup with the metal specimen? Why?
A 2.54-cm. steel bolt is used to clamp two aluminum (2014-T6, HT aged) plates together as shown by Fig. Problem 5. The aluminum plates have a total thickness of 08 cm. and an equivalent diameter of 5.08 cm. The bolt is heated to a temperature of 93.33 oC, the inserted in the aluminum plates, which are at 26.7 oC, and tightened so as to have a tensile tightening stress of 207 MPa in the unthreaded shank while steel at 93.33 oC. What is the tensile stress in the bolt after assembly has cooled to 26.7 oC? The deformations are elastic.
A 30.14 g stainless steel ball bearing at 117.82°C is placed in a constant-pressure calorimeter containing 120 mL of water at 18.44°C. If the specific heat of the ball bearing is 0.474 J/g-°C, calculate the final temperature of the water. Assume the calorimeter to have negligible heat capacity. Specific heat of water is 4.184 J/g-°C .

14. A commonly used method of fastening one part to another part iscalled “shrink fi tting.” A steel rod has a diameter of 2.0026 cm, and afl at plate contains a hole whose diameter is 2.0000 cm. The rod is cooledso that it just fi ts into the hole. When the rod warms up, the enormousthermal stress exerted by the plate holds the rod securely to the plate. Byhow many Celsius degrees should the rod be cooled?
The 8-mm-thick bottom of a 220-mm-diameter pan may be made from aluminum (k = 240 W/m · K) or copper (k = 390 W/m · K). When used to boil water, the surface of the bottom exposed to the water is nominally at 110°C. If heat is transferred from the stove to the pan at a rate of 600 W, what is the temperature of the surface in contact with the stove for each of the two materials?
Q4. Two long rods of the same diameter, one of brass(k= 85 W/mK) and the other of copper (k=375 W/mK) have one of their ends inserted in a furnace and the other ends exposed to the same atmosphere. At a distance of 105mm away from the furnace, the temperature of the brass rod is 120' C. Find the distance from the furnace in which the copper rod have the same temperature.
A square high-density polyethylene [α = 158×10–6/°C] plate has a width of 250 mm. A 150 mm diameter circular hole is located at the center of the plate. If the temperature of the plate increases by 37°C, determine:

To ensure a tight fit, the aluminum rivet used in airplane construction are made slightly larger than the rivet holes and cooled by dry ice (solid CO2) before being driven. If the diameter of a hole is 0.500 cm, what should be the diameter of a rive at 20 degree Celsius if its diameter is equal that of a hole when the rivet is cooled to -78 degree Celsius, the temperature of dry ice? Assume the coefficient of expansion to remain constant. (Given and solutions)
The 5-mm-thick bottom of a 200-mm-diameter pan may be made from aluminum (k= 240 W/m·K) or copper (k= 390 W/m·K). When used to boil water, the surface of the bottom exposed to the water is nominally at 110°C and heat is transferred from the stove to the pan at a rate of 1200 W. What is the temperature of the surface in contact with the stove for each of the two materials?Aluminum:T= _____ °CCopper:T= _____ °C
1. The boiling temperature of water is 100 °C. If you put boiling water in a mugplaced at the table top, you observed that after some time the water cools down,decreasing the temperature of water in the mug. Why is this so? Explain using theZeroth Law of Thermodynamics. What happens to objects when temperature increases? For instance, a jar cover an be removed by putting the cover in hot water. Why is this so?
