There are different techniques to reduce friction, similar to 1. Cleaning the surfaces 2. Including lubricants 3. expanding the temperature 4. wetting the surface 5. expelling polluting influences. Egyptian could have moved the square through water, which would be Fluid Friction, and makes it less demanding to move.
Answer : The pressure at this new altitude is, 364.2 mmHg
Explanation :
Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.
or,
where,
= initial pressure = 760 mmHg
= final pressure = ?
= initial volume = 62.3 L
= final volume = 130 L
Now put all the given values in the above equation, we get:
Thus, the pressure at this new altitude is, 364.2 mmHg
Answer: If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
hope it helps!!
The process of condensation it releases energy up into the atmosphere where the clouds form.
