A flask is filled with 1.52 L (L = liter) of a liquid at 95.6 °C. When the liquid is cooled to 12.2 °C, its volume is only 1.38 L, however. Neglect the contraction of the flask. What is the coefficient of volume expansion of the liquid? Number Units the tolerance is +/-2%

A cylindrical glass flask with a diameter of 8 cm and the height of 20 cm is fully filled with water at 20°C. When the temperature of the water (and consequently the inner surface of the flask) is raised to 100° C, determine the volume of the water that overflows? HINT 1: Don't forget to calculate the initial volume of the water and flask HINT 2: The volume expansion coefficient for ordinary glass and water can be found in the table of Week 4 (Slide #20). HINT 3: Calculate the volume expansions for both water and the flask HINT 4: The difference between the final volume of water and the final volume of the flask is the amount of overflow.

You happen to come across a piece of metal that has a density of p 8.12 g/cm3 when the temperature is To = 42.5 °C. If the metal is cooled to a temperature of T1 0.00 °C, does the density change? Yes, the density will decrease since the volume changes. Yes, since the metal contracts and the mass is constant, the density will increase. No, because as the volume changes so does the mass. No, density does not depend on temperature. Calculate the density of the piece of metal at this temperature, P1. The coefficient of volume expansion for this piece of metal is B = 7.62 x 10-5 1/°C. -0.0263 Pi = g/cm3 Incorrect

The volume of a gas at 20°C is 100cm3 at normal pressure. If it is heated to 100°C, its volume becomes 125cm3 at the same pressure, then volume coefficients of the gas (at normal pressure) is? a) 0.0033/°C b) 0.0025/°C c) 0.0030/°C d) 0.0021/°C

A pot of water is boiling under one atmosphere of pressure. Assume that heat enters the pot only through its bottom, which is copper and rests on a heating element. In two minutes, the mass of water boiled away is m = 2.5 kg. The radius of the pot bottom is R = 8.0 cm and the thickness is L = 1.0 mm. What is the temperature of the heating element in contact with the pot? TE = Number i Units

If 23.5 moles of an ideal gas occupies 0.0465 cubic meters at 14.5 °C, what is the pressure of the gas? pressure: Pa

A gas under constant pressure has a volume of 30.57m^3 and a temperature of 59.0 K. A change in temperature caused the volume to change to 121.14m^3. Based on the relationship between volume and temperature, what must have happened to the temperature? A- Temperature decreased B- Temperature increased C- Temperature stayed the same D- Temperature trend can not be determined

A hot air balloon uses the principle of buoyancy to create lift. By making the air inside the balloon less dense then the surrounding air, the balloon is able to lift objects many times its own weight. A large hot air balloon has a maximum balloon volume of 2090 m3. a.  If the air temperature in the balloon is 54 °C, how much additional mass, in kilograms, can the balloon lift? Assume the molar mass of air is 28.97 g/mol, the air density is 1.20 kg/m3, and the air pressure is 1 atm.

Large helium-filled balloons are used to lift scientific equipment to high altitudes. (a)What is the pressure inside such a balloon (in atm) if it starts out at sea level with a temperature of 24.8°C and rises to an altitude where its volume is sixteen times the original volume and its temperature is  −41.7°C?  (Enter your answer to at least 3 decimal places) _______________ atm   (b)What is the gauge pressure? (Enter your answer in atm and to at least 3 decimal places. Assume atmospheric pressure is constant.) ________________ atm
