Answer:
Heating is the best method
Explanation:
When a mass of crystals containing Water of crystallization is heated sufiiciently to a high temperature, water vapor may be driven off the crystals by the action of heat alone.
The easiest way to approximate ph level is through the ph paper measurement system because using pH paper would be best for doing a quick measurement in the field. It does not essentially need to be calibrated or standardized and the papers make available an instant estimate.
Personally, I would chose #1-Long chains of carbon molecules
Eukaryotes are multicellular organisms. So, just about every ant, bee, and termite you can think of qualifies. Also, if you consider herds applicable, you can add elephants, zebras, and lions.
It will occupy 18 L volume when the pressure is changed to 0. 5 atm and the temperature remain constant.
Calculation,
According to Boyle law, the pressure of a given quantity of gas varies inversely with its volume at constant temperature.
.....(i)
- is initial pressure = 3 atm
- is initial volume = 3L
- k is constant
(ii)
- is final pressure = ?
- is final volume = 0.5atm
- k is constant
Combining equation (i) and (ii). we get,
3 atm× 3L= × 0.5atm
= 3 atm× 3L/0.5atm = 18 L
Boyle law used during respiration or breathing.
