76.6 litres is the volume of the gas if pressure and temperature changes to STP.
Explanation:
Data given:
Volume of the gas V1 = 15.9 litres
pressure of the gas P1 = 589 kPa or 5.81 atm.
temperature T1 = 56.5 degrees or 329.3 K
Final pressure P2 = 101.3 kPa
Final temperature T2 = 273 K
At STP the pressure is 1 atm or 101.3 kPa and the temperature is 273 K. So from the question the final temperature and pressure is at STP.
from Gas Law:
=
V2 =
Putting the values in the above rearranged equation of Gas Law:
V2 =
= 76.6 Litres
Answer:
The electrons are attracted to the nuclei of both atoms.
Explanation:
Electrons are attracted to nuclei because nuclei are positively charged and electrons are negatively charged. Opposites attract
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.
