Ammonium chloride absorbs thermal energy as it dissolves in water. Rodrigo designed an airtight, watertight pouch. He put a carefully measured amount of ammonium chloride in it. He added a measured amount of water to the ammonium chloride, sealed the pouch tightly, and then wrapped the pouch around a small bottle of water. Rodrigo's device is intended to bottled drinks. He can test how well his device works by measuring the total change in temperature of the Next, Rodrigo should see if he can use the results of his test to improve the of his design.

3 hours because it is a decent distance.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
