- 1.46 (a) For an ideal gas, use an equation like (1.30) to show that dP = P(n¯¹ dn + T¹¹ dT - V¹ dV) (which can be written as d ln P = d ln n + dln T - d ln V). (b) Suppose 1.0000 mol of ideal gas at 300.00 K in a 30.000-L vessel has its tempera- ture increased by 1.00 K and its volume increased by 0.050 L. Use the result of (a) to estimate the change in pressure, AP.

X Incorrect; Try Again; 5 attempts remaining Use the equation Fel = K(Q₁ Q₂/d²) to find the electrostatic force between the two particles. Q₁ and Q2 are the charges on the particles (charge of a proton here), and d is the distance of separation. The constant is given in the introduction and has the units Nm²/C². This means that the distance must be converted from picometers to meters using the relation 1 pm = 1 × 10¯ m. -12High fructose corn syrup is a sweetener found in everyday food items especially carbonated beverages. It is derived from the "fruit" of corn using a bioprocess that degrades corn starch into its constituent sugars. Given the quantity of corn syrup (d = 1.4 kg L^-1) needed for many industries. It should be no surprise that this product is often transported from place to place in tank cars (via railway) where the typical transport mass is 2.290 x 10^5lbs. In the space provided below, calculated the diameter in (meters) of such a tank car's 11.12m long-cylindrical transport container. Recall that 1 gal =3.785 L, kg= 2.205lbs, and 1cm^3 =exactly 1mL
