- A 5-mmdiameter hailstone has a terminal velocity of10.0m/s. Assuming its mass is6.031025 kg and all of its kinetic energy turns into heat, calculate the temperaturechangeof the hailstone when it hits the ground and stops. The heat capacity of ice is 2.06J/g.K.In the equation w = P V, why is there a negative sign?The Dieterici equation of state for one mole of gas is p=RTe-aVRTV-b Where a and b are constants determined experimentally. For NH3g, a = 10.91 atm. L2 and b = 0.0401 L. Plot the pressure of the gas as the volume of 1.00 mol of NH3g expands from 22.4 L to 50.0 L at 273 K, and numerically determine the work done by the gas by measuring the area under the curve.

If the air temperature in your area is 107ºF with a relative humidity of 8%, how hot does your body feel? b. If the air temperature and relative humidity is known to be increasing at a rate of 2°F per sec and 1% per sec, resp., how fast is the heat index changing at the moment when the air temperature in your area is 107°F with a relative humidity of 8%?Industries use both open and closed systems. Which of the following is an example of a closed system? In the core of a nuclear reactor, water is heated by the nuclear reaction and changes state to steam. The steam runs through pipes into a vat of fresh water, and the heat flows out of the steam into the fresh water. The steam condenses into liquid water, and is pumped back into the core of the reactor. In a fractional distillation tower, crude oil is heated, and separated using the boiling points of the various components. The components are pumped to different sections of the plant to undergo further reactions. A boiler burns methane gas to heat water into steam, which is then pumped into a reaction vessel where it reacts with organic feedstock to produce hexanol. Sulfur dioxide gas is reacted with oxygen gas to produce sulfur trioxide. This gas is then bubbled through water to produce sulfuric acid, which is pumped out of the reaction vessel.
