The density of water that is at 0°C is very nearly 1000 kg/m³ (it is actually 999.84 kg/m³), whereas the density of ice that is at 0°C is 917 kg/m³. Calculate the pressure necessary to keep 4.6 m³ of water from expanding when it freezes, neglecting the effect such a large pressure would have on the freezing temperature. (This problem gives you only an indication of how large the forces associated with freezing water might be.) The bulk modulus of ice is 2.20 x 109 N/m². How is density related to the mass and volume of a substance? How is the change in volume due to expansion or contraction related to the thermal stress? N/m²

- A 7.97 m3 tank contains 10.5 g of chlorine gas (Cl2) and an absolute pressure of 5.50 × 105 Pa. The mass per mole of Cl2 is 70.9 g/mol. (a) Determine the temperature of the tank in Celsius. (b) Later, the temperature of the tank has dropped to 33 °C and, due to a leak, the pressure has dropped to 3.30 × 105 Pa. How many grams of chlorine gas have leaked out of the tank?Scientists experiment with a balloon near a Himalayan fresh water lake at an altitude of 5000 m where atmospheric pressure is half of that at sea level. The temperature of the lake is uniform with depth and identical to the air at the surface of the lake. To what depth should a balloon be taken under the lake to reduce its volume by a factor of 4? answer: 20mStep 1 (a) The ideal-gas equation describes each condition of the air in the tire. We will set up ratios in order to describe these changes. Dividing the equations PV = nRT in the initial and final states, we have PfVf Tf P¡Vi Ti Solving for the final pressure in the tire, gives Pf = = = which gives I Tf P(V)() P₁ Vf T₁ = (1.013 x 105 Pa) x 105 Pa. Note that the volume V¡ cancels out of the equation. = Vf Po = Pr (V ( ) ( ) Pd Pf Vi V₁ Step 2 (b) After the car is driven, the temperature and volume of air in the tire have changed. Let Td be the temperature and Vd be the volume of air in the tire. We have PdVd Td PfVf Tf' x 105 Pa 273 + 273 + Vf Vf Again we see that the volume Vf cancels out of the equation. °C K °℃ K = x 105 Pa.
- The absolute pressure in your car tires is 3.7 × 105 Pa at a temperature of 35.0°C when you drive it onto a ferry boat to Alaska a. What is the absolute pressure of the tires, in pascals, later when the temperature has dropped to -40.0°C? Assume the volume of each tire does not change.Suppose you have a large hot air balloon, open at the bottom but filled with air that is heated to 50 °C while the outside air is 10 °C. What can you say about the air inside the balloon and how much it can lift? The density of air is surprisingly high: 1.23 kg/m3, an average hot air balloon has a volume of 3000 m3 , and the acceleration of gravity is 9.8 m/s2. The density is higher by the factor (273 + 50)/(273+10) = 1.14 and therefore will not have a buoyant force and will not lift off the ground with any load. The density is lower by the factor (273 + 10)/(273+50) = 0.88 and therefore will have a buoyant force of 0.88 times the weight of the air it replaced, or about 32,000 N. The density is lower by the factor (273 + 10)/(273+50) = 0.88 and therefore will have a buoyant force of 0.12 times the weight of the air it replaced, or about 4300 N. The density is the same but the pressure of the hot air is higher by (273 + 50)/(273+10) =…In everyday experience, the measures of temperature most often used are Fahrenheit F and Celsius C. Recall that the relationship between them is given by the following formula. F = 1.8C + 32 Physicists and chemists often use the Kelvin temperature scale. You can get kelvins K from degrees Celsius by using the following formula. K = C + 273.15 (a) Calculate that value.K(25) = (b) Find a formula expressing the temperature C in degrees Celsius as a function of the temperature K in kelvins.

F = (d) What is the temperature in degrees Fahrenheit of an object that is 272 kelvins?

We increase the temperature of the container to 77, leaving it closed, and read a pressure gauge attached to the container. Initially the reading was 101 KPa (kilopascals, or 1000 N/m2). What is the new reading? Give your answer in KPa.
