To find the heat of vaporization, we need to plug in the values for slope, temperature, and gas constant into the equation. The given temperature is in Kelvin, so we do not need to convert it. However, we need to convert the slope from K to Kelvin^-1 by dividing...
Answer to: How do you find the number of moles of a gas if the pressure is 1.00 atm, the volume is 800 L, the temperature is 325 K, and KE = 4.05...
Find the molar enthalpy of vaporization for a substance, given that 3.21 mol of the substance absorbs 28.4 kJ of energy as heat when the substance changes from a liquid to a gas. Why is it that for calculating enthalpy of formation, you subtract the reactants from the products, but when...
For a quick definition dew point is the temperature at which air becomes saturated with respect to a plane surface of water. If you're a bit interested in meteorology, environmental science, or agriculture you may find this interesting.
With a ruler, you can match the scales across the chart. Step 8: Find the second set of diagonal lines which identify wet bulb temperature. Though these lines are close to the enthalpy lines, they’re not actually parallel. When using Airtable’s PDF psychrometric chart, there are some...
However, hcv is the maximum heat energy that the complete combustion releases on the burning of the fuel. We refer to it as the gcv of the fuel. We can subtract from the hcv, an amount of heat required to evaporate the water formed, we can easily find Lower Calorific Value (LCV). Be...
Room for More.When I'm not sure if I'll run out of space in my luggage for bottles I'll find at my destination, I put a zipper-closed canvas bag in my luggage. That way if I bring home a ton of booze, I can put the extra dirty clothes and toiletries into the zipper bag and...
How do you convert the pressure 0.250 Atm to kPa? How do I find the change in temperature? The pressure of a gas is 25 atm at 475 K. Find its temperature at standard pressure. (STP = 1 atm.) If both temperature and volume of an ideal gas are halved, how does the pressu...
Calculate the energy needed to bring a cup of water (about 250 g) from 10 C to the boiling point. Then find the time it takes to heat this water A kettle draws power of 2000 W and has an efficiency of 85%. You fill the...
Heat is a form of energy that is transferred when there is an appreciable temperature difference. The same is stated by the zeroth law of thermodynamics. Heat absorbed by the system is positive and heat released out of the system is always considered negative....
