Interpretation:
The units of 70.5 and 8.27×10-7 should be calculated.
Concept introduction:
The density of a fluid is given by the empirical equation,
It is assumed that the given equation is valid and therefore dimensionally homogeneous. So, the dimension of the left hand side and right hand side of the equation is equal.

- The beach ball’s volume will increase when Molly goes to the beach. Charles Law can be used to verify this because the pressure inside the beach ball is constant. V1=8.0 L, T1=19 °C, T2= 33 °C. For our Celsius numbers, we must convert them to Kelvin. The temperature can be converted from Celsius to Kelvin just by adding the number 273 to it. T1= (19 °C+273) K, T1= 292 K. T2= (33 °C+273) =, T2=306 K. According to Charles Law, V1/T1=V2/T2. Therefore, 8.0 L/292 K=V2/306 K, V2*292 K=8.0 L*306 K. V2-292 K/292 K=2448 L/292 K. The 292 K cancels out. So, V2= ? L. Since, the volume of the beach ball has increased from 8.0 L to 8.4 L it is fair to say that the beach ball has expanded. When the temperature of the object containing gas increases, it has to expand so the pressure is kept constant. The gas law used to solve this problem is Charles’s Law which states that the volume of a gas is directly proportional to its absolute temperature of the gas when pressure is kept constant. By applying…arrow_forwardThe density of mercury changes approximately linearly with temperature as p=851.5-0.086T in Ibm/ft^3 (T in degrees F), so the same pressure difference will result in a manometer reading that is influenced by temperature. If a pressure difference of 14.7 Ibf/in^2 is measured in the summer at 95F and in the winter at 5F, what is the difference in column height between the two measurements? 273.488 in O 1.899 ft O 273.488 ft O 8.493 ftarrow_forwardNitrogen gas in a cylinder has a pressure of 1.85x10^3 psi.

- High-pressure liquid chromatography (HPLC) is a method used in chemistry and biochemistry to purify chemical substances. The pressures used in this procedure range from around 500 kilopascals (500,000 PaPa) to about 60,000 kPakPa (60,000,000 PaPa). It is often convenient to know the pressure in torr. If an HPLC procedure is running at a pressure of 5.50×108 Pa, what is its running pressure in torr? Express the pressure numerically in torr.arrow_forwardWhat Celsius temperature, T2T2T_2, is required to change the volume of the gas sample in Part A (T1T1T_1 = 15 ∘C∘C , V1V1V_1= 1.70×103 L ) to a volume of 3.40×103 L? Assume no change in pressure or the amount of gas in the balloon. Express your answer with the appropriate units. A sample of gas in a balloon has an initial temperature of 15 ∘C and a volume of 1.70×103 L . If the temperature changes to 91 ∘C , and there is no change of pressure or amount of gas, what is the new volume, V2V2V_2, of the gas? Express your answer with the appropriate units. A gas has a volume of 10 LL at 0 ∘C. What is the final temperature of the gas (in ∘C) if its volume increases to 39 LL ? Assume that the amount of the gas and its pressure remain unchanged.arrow_forwardA student breaks a thermometer and spills most of the mercury (Hg) onto the floor of a laboratory that measures 15.2 m long, 6.6 m wide, and 2.4 m high. The vapor pressure of mercury at 20°C is 1.7 x 10-7 atm. Calculate the mass of mercury vapor (in grams) in the room at 20°C. MW of Hg=200.6 g/mol; 1atm =101325 Pa; R=8.314 J/K mol;arrow_forward

Express you answer as three significant digits in moles (enter: mol).arrow_forwardIn 1783, Jacques Charles launched his first balloon filled with hydrogen gas, which he chose because it was lighter than air. The balloon, which had a volume of 31 000 L at STP, reached an altitude of 1000 m, where the pressure was 663 mmHg and the temperature was -3 ∘C.
