After a quick visit to the local bakery you decide to cut the steaming hot loaf of bread. You then notice that the bread decrease in physical size when you try to cut it with a large knife. Your mother then advises you to allow the now 'slightly smaller' loaf to cool off for about 20 minutes before you attempt to cut it again... What happened to the density of the loaf of bread after you 1st attempted to cut it? O A. Not enough information is supplied to figure this one out! OB. The bread density most probably decreased a little. OC. The bread density most probably stayed the same. D. The bread density most probably increased a little. Reset Selection

The rectangular plate shown in Figure P16.60 has an area Ai equal to w. If the temperature increases by T, each dimension increases according to Equation 16.4, where is the average coefficient of linear expansion. (a) Show that the increase in area is A = 2Ai T. (b) What approximation does this expression assume?
(a) Use the ideal gas equation to estimate the temperature at which 1.00 kg of steam (molar mass M=18.0 g/mol) at a pressure of 1.50106 Pa occupies a volume of 0.220 m3. (b) The van der Waals constants for water are a=0.5537 Pa m6/mol2 and b=3.049105 m3/mol. Use the Van der Waals equation of state to estimate the temperature under the same conditions. (c) The actual temperature is 779 K. Which estimate is better? `
The measurement of the average coefficient of volume expansion for a liquid is complicated because the container also changes size with temperature. Figure P19.62 shows a simple means for measuring despite the expansion of the container. With this apparatus, one arm of a U-tube is maintained at 0C in a water-ice bath, and the other arm is maintained at a different temperature Tc in a constant-temperature bath. The connecting tube is horizontal. A difference in the length or diameter of the tube between the two arms of the U-tube has no effect on the pressure balance at the bottom of the tube because the pressure depends only on the depth of the liquid. Derive an expression for for the liquid in terms of h0, hi and Tc.
A hollow aluminum cylinder 20.0 cm deep has an internal capacity of 2.000 L at 20.0C. It is completely filled with turpentine at 20.0C. The turpentine and the aluminum cylinder are then slowly warmed together to 80.0C. (a) How much turpentine overflows? (b) What is the volume of the turpentine remaining in the cylinder at 80.0C? (c) If the combination with this amount of turpentine is then cooled back to 20.0C, how far below the cylinders rim does the turpentines surface recede?
The height of the Washington Monument is measured to be 170.00 m on a day when the temperature is 35.0 . What will its height be on a day when the temperature falls to -10.0 ? Although the monument is made of limestone, assume that its coefficient of thermal expansion is the same as that of marble. Give your answer to five significant figures.
An underground gasoline tank can hold 1.00 103 gallons of gasoline at 52.0F. If the tank is being filled on a day when the outdoor temperature (and the gasoline in a tanker truck) is 95.0F, how many gallons from the truck can be poured into the tank? Assume the temperature of the gasoline quickly cools from 95.0F to 52.0F upon entering the tank.
It is often possible to loosen the metal lid on a hard-to-open glass jar by running hot water over top of it for a few moments. Why does this happen and what does this tell you about the properties of metal and glass?
A scuba diver has his lungs filled to half capacity (3 liters) when 10 m below the surface. If the diver holds his breath while quietly rising to the surface, what will the volume of the lungs be (in liters) at the surface? Assume the temperature is the same at all depths. (The density of water is 1.0x103 kg/m3
A diving bell has an air space of 3.0 m3 when on the deck of a boat. What is the volume of the air space when the bell has been lowered to a depth of 50 m?Take the mean density of sea water to be 1.025 g em-3 and assume that the temperature is the same as on the surface.
A bubble having a diameter of 92 cm is released from a depth of 4.5 m from the bottomof a swimming pool. The temperature of thewater at the surface is 22◦C, whereas it is 16◦Cat the point of release.What will the diameter of the bubble bewhen it reaches the surface? The accelerationof gravity is 9.8 m/s2and the density of wateris 1000 kg/m3.Answer in units of cm.
Hi! I have a question. Unsatisfied with the Celsius and Fahrenheit temperature scales, you decide to create your own. On your temperature scale, the ice point is 77°M and the steam point is at 437°M, where "°M" stands for "my scale." What temperature on your scale corresponds to 68°F? (A) 154°M, (B) 168°M, (C) 140°M, (D) 136°M, (E) 149°MMy answer below, is this correct?68°F = (E) 149°M
