For many years, drinking water has been cooled in hot climates by evaporating it from the surfaces of canvas bags or porous clay pots. How many grams of water can be cooled from 35°C to 25°C by the evaporation of 38 g of water? (The heat of vaporization of water in this temperature range is 2.4 kJ/g. The specific heat of water is 4.18 J/g·K.) Answer should be in KJ.

We purchased an alleged 10,000 gallon water tank.Yet we have had water delivered by a tanker that can only hold 4,400 gallons and the tank is 75% full.We talked to the builder,and all he quoted were some metric measurements(5.1metres diameter and 2.65 metres in height) which is the correct dimensions of our physical tank.So,what is going on?Any thoughts on this problem?Thank you to everyone who takes this on board.

Its replacement the James Webb Space Telescope; Will it be built as a one shot project or will it be designed to be serviced from time to time?

Well considering the trials that were learned servicing the Hubble, wouldn't it stand to reason that if the JWST were designed to be serviceable, wouldn't it be practical to simplify certain aspects of its components so that servicing & replacement could be preformed by a robotic service drone?

NASA it appears won't have the capacity to do the maintenance when and if the need is required. Which leaves the Astronomy Interests of those concerned pretty much up the proverbial "creek" with the rapids on the horizon (lets pray it isn't the crest of a waterfall).

Perhaps where servicing capacity is required, would NASA consider building a Mini Shuttle for a crew of 2 or 3, for the exclusive purpose of servicing orbital platforms?

Either Crewed by Humanoids or an elaborate robot, a servicing capability is definitely needed.
